Einleitung

Diese Anleitung zeigt wie das SATA Kabel entfernt wird.

Bevor du am iMac arbeitest: Ziehe den Netzstecker und halte den Anschaltknopf für mindestens zehn Sekunden gedrückt, um die Kondensatoren der Stromversorgung zu entladen.

Sei sehr vorsichtig und berühre keine Leitungen der Kondensatoren oder freiliegende Lötstellen auf der Rückseite des Netzteils. Fasse die Platine nur an den Kanten an.

    • Reparaturen sind relativ schwierig, wenn der iMac aufrecht steht und man keine iMac Reparaturhilfe verwendet. Man kann den iMac zwar auch für Reparaturen hinlegen, jedoch ist es einfacher und schneller den iMac in aufgerichtetem Zustand zu reparieren.

    • Wenn du die Reparaturhilfe aus Karton von iFixit hast, dann baue sie erst mit Hilfe dieser Anleitung zusammen.

    This instruction page is not clear and is ambiguous if you have to do all the steps to just change the power supply please clarify another words do I have to remove the speaker and the hard drive to replace the power supply?

    This is a display removal guide not the power supply guide!Here’s the guide you need to follow for that iMac Intel 27" EMC 2546 Netzteil ersetzen

    Didn’t need the cardboard wedge to remove the display. Waste of money. Lay your Mac on its back.

    • Beginne an der linken Seite des Bildschirms, auf der Seite der Ein-/Aus-Taste, und schiebe das iMac Opening Tool zwischen Bildschirm und Gehäuse.

    • Die Achse am iMac Opening Tool verhindert, dass es zu tief in das Gerät gesteckt wird. Solltest du jedoch ein anderes Werkzeug benutzen, stelle sicher, dass du es nicht weiter als 9,5 mm in den iMac steckst. Es besteht sonst die Gefahr, Antennenkabel oder andere Komponenten zu beschädigen.

    Would a heat gun make this step easier? Or damage the iMac?

    Clark Green -

    A heat gun wouldn’t help you here as you still need to cut though the adhesive. You also risk damaging the display with the excessive heat.

    Dan -

    Removing the original adhesive is easier than removing newly applied adhesive (e.g., if you have to reopen iMac).  If you should happen to need to reopen the iMac, please use extreme caution and highly consider my suggestions below.

    When using the pizza cutter tool, do the first few steps in reverse starting with step 8.  Starting on the left side is better since this is where the adhesive is narrowest.  The right side has two antennas and the top right has one, see the pictures for step 18-21, they are the brass colored metal rectangles near the edges.  The adhesive on these pieces are wider and therefore have more holding power.  The thickness of the pizza cutter tool is enough to crack the glass.

    Walter Hayden -

    Continuing from my previous comment.  To remove the adhesive on the right side you’ll need to create a very slight gap to give the pizza cutter some more room.  Do this by cutting the adhesive on the left side up and around to the camera.  Before attempting to cut the right side. Carefully slide the plastic cards (I purchased two sets) to ensure the adhesive on the left top and side is completely free.  Now slowly move towards the right side.  After every inch or two of removing new adhesive, slide the card over to create this slight gap.  Be careful to not move the card too close to where the adhesive has not been cut.  You want to create a very slight gap without creating too much pressure.  Use extra caution with approaching the areas where the antenna are since the adhesive is stronger here and will need some additional cutting.  Follow this approach all the way around the right side.  Be careful to not create too much pressure at any one time.  Good Luck!.

    Walter Hayden -

    I can confirm with Walter - trying to remove freshly applied adhesive is WAAAAY harder! My pizza cutter didn’t work correctly (the circle became a rectangle!) and I ended up with a small crack on the left of my screen. Dang it!

    Benon Koebsch -

    I would highly, highly, highly recommend AGAINST doing this at home. I followed these instructions to a T, and still somehow managed to have the screen not be able to turn on after the hard drive replacement. Then, once you’ve opened your Mac yourself, Apple will refuse to fix anything on the computer, and even other third party, Apple-authorized repair facility will refuse to repair it for you, and you will have to locate a non-authorized Apple repair facility. There, I am having to pay ~$600 to fix things that got screwed up, even though I followed the instructions here to a T, step by step, and did everything slowly and methodically.

    Beware, if you’ve never done this before, that be locked out of ever being able to use an Apple repair facility, or Apple-authorized repair facility, if you mess things up here now.

    Luke Gibson -

    I performed this on a Late 2015 iMac and there weren’t any significant differences to these steps, but I did find the repair to be nerve-wracking. My model cost nearly $3,000 and about 10 steps into this guide (which I did fully read ahead of time) I was thinking, “what have I got myself into?” But I didn’t rush and happily I’m typing this on my repaired iMac! I found a video from OWC that was more useful than the photos in this guide for certain steps: https://vimeo.com/139364064

    Anthony Zimmerman -

    Don’t know if you are still around, but THANK YOU for posting this video! The video made it seem SO NOT SCARY and, in conjunction with the photos and comments and tips on this guide, was a lifesaver. Big thumbs up.

    Melissa Ortiz -

    First impressions so far: yes it can be a bit nerve wrecking if it is your first time doing this sort of thing and even with lots of experience with a 2011 model it’s still a bit unsettling haha (nervous laughter).

    What I recommend: use a guitar pick to start cutting the glue. You’ll need a bit of pressure so do just the tip.

    Once you’ve done the whole perimeter (minus bottom) do it again but now it should be easier to go deeper so go very slow and careful. Then get the old suction cups used to open older models and start lifting the display very carefully to see where it’s still glued and cut those as well.

    Then you should be done and now the real fun begins! :D

    Carlos Ferrari -

    It’s ridiculous. Apple should pay for doing this. Like glue parts together to block a repair / make difficult. I smashed my iMac. FU Apple. Seriously, every product I owned had hardware issues. For example, bad solder joints. Never again Apple. I’m happy with Windows and in 2018 / 2019 there are many other manufacturers with high quality stuff. Apple is dying, if they do not change …

    Depple -

    NOTE: I followed every step word for word, but the adhesive strips supplied are as bad as double sided tape. Within 48hours the screen had slipped off and cracked. Now I need to fork out for a new screen and try again.

    Not sure what to try next time with strips? Perhaps a bit of glue to help hold it??

    Dan Kelly -

    Where do i get the “iMac Opening Tool?” its neither in the list of tools nor could i find it on the tool page.

    Patrick Cella -

    Hi @snappadoodle! The opening tool is included in the adhesive kit included in the tool list, but you can purchase it separately here.

    Sam Goldheart -

    After disconnecting the power cord and before cutting the panel adhesive, push and hold the power button for 10 seconds. This will discharge the power supply capacitors. In case you accidentally touch the solder joints on the board, you won't be shocked and drop the panel.

    Paul Floro -

    Bottom line: This repair seems to have worked (so far no more intermittent shut-downs). Thanks iFixit!

    As a novice who fully expected to destroy the display or worse, I make the following recommendations: (1) Before you start, read the steps several (many) times; visualize doing them and imagine how things could go wrong; (2) Read all the comments—there were some really helpful tips—like simply displacing the left speaker rather than fully removing it; (3) Get the recommended tools*; and (4) take your time—if you start to feel frustrated—seriously, stop and take a calming breath. Time is your friend. Failure is not an option.

    *I would add a 3-prong parts puller to the tool list—it’s great for pulling and starting loose screws so you don’t drop them down into the chassis like I did. It’s also great for retrieving the screws you’ve dropped into the chassis.

    Brad Bauknecht -

    Hi brad, what exactly did you repair to stop the shutdowns? I’m having the same issue

    merinian -

    Merinian: I replaced the power supply and it’s still working fine at this late date. No more intermittent shut-downs. Fingers still crossed!

    Brad Bauknecht -

    Just completed the Core i5 to i7 CPU upgrade and can strongly recommend getting the “pizza tool” to cut the display adhesive. It worked flawlessly and was done in less than 5 minutes. No inadvertent cables cut. No display problems.

    John Fisk -

    Thank you very much for the instructive tutorial. I just successfully replaced the hard drive on my 2012 iMac 27. I used a disposable surgical scalpel 15 blade, and locked the blade extending 9 mm from the scalpel shaft using office tape. I used regular double sided tape to reattach the screen. I cut the strips using the scalpel. I have no previous computer experience and this is the first time I replaced a computer part. This was easy and fun.

    Filip Dolatowski - Friday 11th Dec 2020

    Filip Dolatowski -

    You are very lucky! I’ve had three systems come in which someone did the exact same thing! All three cut the display ribbon cables. Please don’t use surgical knifes or any other knife! Use the proper tool the special pizza cutter wheel designed for the task.

    .

    You likely spent more on the knifes than what the wheel cost with the correct tapes. You make the next time doubly hard to open not using the correct tapes! Hows the built in microphone? You may have messed it up.

    Dan -

    Thank you very much for the tutorial. You are the best!

    After reading all the post here I almost gave up doing this on my own. But I did it anyway and was succesful. I would recommend everyone to use the rollcutter. There is no risk of harming the screen if you use it. And in my case it was enough to open the imac. If you do not harm the screen connector or the screen the biggest part is done. It gets easier once you`ve stacked your screen somewhere safe. The parts inside are mostely not as delicate as the heavy and expensive screen!

    Take your time and work carefully. It is definitely doable!

    CONSULTINEL -

    I found the cutter tool that came with my kit to work just fine. The wheel is extremely thin and I had no problem inserting the wheel to begin cutting. I follow the guide for the most part but took my time and use the cutting wheel slowly and then repeated the process a few times. Once I was able to pry the screen back about an inch I used the other end of the tool to cut additional adhesive that was still clinging to the body of the iMac and the screen. Having just replaced the power supply, and having my iMac running again, I do not think I will use the adhesive strips to reattach the screen. The screen fit back in place no problem which I did to test my Mac. Because the iMac screen sits at an angle I am quite comfortable that the screen is not gonna fall off. Also while having a screen off I was able to clean the inside of the Mac of dust buildup. I think I will only use the adhesive strips down the road if I’m gonna sell the Mac, which means I can give it a good clean before securing the screen.

    James Orwin -

    If the screen falls off (which it will do!) it will damage the parts which would be a lot more expensive! PLEASE get the correct tapes and properly mount the screen back on.

    Think of it this way how many people have shot them selves with a gun not realizing it was loaded or set to go off!

    Dan -

    I think Dan is right as I decided it best to complete the process with the adhesive tapes to secure the screen. I just took some time to do a complete clean of the interior before sealing the display.

    • Benutze das Werkzeug wie einen Pizzaschneider - rolle es entlang des Schlitzes zwischen Bildschirm und Gehäuse und es wird den Kleber durchschneiden.

    • Stelle sicher, dass du den Griff immer hinter dem Rad hinterher schiebst. Ansonsten könnte das Rad aus dem Griff herausrutschen.

    • Fahre mit dem Werkzeug entlang der linken Gehäuseseite.

    I found the 'pizza cutter' surprisingly smooth at cutting through four-year-old adhesive.

    Gerry -

    In my experience the cutter also worked very well for cutting the original adhesive. Unfortunately when I was reinstalling the display with the new adhesive strips, somehow the display power connector came loose. I had to open the display a second time and the cutter was not as effective against the new adhesive. I managed to break the cutter tool plastic wheel and cause a few small cracks in the edge of the displays glass as I worked! Be careful and go slowly!

    azaadkb -

    The cutting tool worked great until I accidentally twisted it a bit while rounding a corner. A chunk of the wheel snapped off, making the rest of the job quite a bit more challenging. Just make sure you are keeping the tool directly parallel with the screen.

    BARRY RODRIGUEZ -

    I concur, opening the screen a 2nd time is considerably more difficult because the adhesive strips are thinner than the original, which makes getting the cutting tool inserted much more difficult….as a result unknowingly I elongated a small crack to a much longer crack and somehow, the LCD now has a wide grey strip from top to bottom….The first time opening was easy, second time resulted in a ruined screen.. The cost of. a replacement LCD is the same has replacing the entire computer….I would recommend anyone attempting to remove the screen for any reason, do not use the aftermarket adhesive strips if you ever intend to open it up; again, or cut the strips much shorter, or possibly use a few pieces of scotch tape or similar to hold the screen in place….since the screen tilts back, this should not be a problem…Good luck…

    • Schneide den Kleber entlang der oberen linken Gehäuseseite durch.

    The pizza cutter will sink in all the way to the tool handle when the adhesive is full cut, but don’t feel you have to do this in one motion. Some parts cut easier and some require a lot (like 20x) of gentle back and forth.

    • Zerschneide den Kleber weiter entlang der oberen Gehäuseseite.

    • Du solltest mit dem Gerät immer etwas vor- und zurückrollen durch den Teil, den du bereits durchgeschnitten hast, um so viel wie möglich von dem Kleber zu lösen.

    what about the part where the camera is though? do I just treat it like the rest of the screen?

    Boris -

    yes. the tool can’t go too deep

    flow in -

    I measured a depth several positions.

    - About 6 centimeters near iSight Camera center, you must no use iMac opening tool, because iSight element exists.

    - iMac opening tool has a 9mm radius, so it may break iSight camera element.

    - Making a plastic card stacking 2 or 3 to 3mm, under the iMac opening tool, that makes inserting a gap 5~6mm like below.

    @. iMac opening tool

    ====== plastic card3 (credit card 1mm)

    ====== plastic card2 (1mm)

    ====== platic card1. (1mm)

    ———————————————— isight camera element (total 5~6cm) ————

    In my case, i got a display problem where lcd display yellow connector was torn without care.

    Be helpful.

    I didn’t have the fancy cutter or cards. So I used my actual pizza cutter. Followed directions just the same, and it easily cut through the adhesive w/o issues or marring the surfaces. Actually used it to rock back and forth to lift the screen. It’s all about taking your time. I rolled it back and further until cut thru. The 3/8 to 1/4 inch is right, but the screen framing actually prevents further depth unless you force it further. The adhesive actually protected the glass while cutting thru, so no damage. Great instructions, but where to get the replacement adhesive to reinstall?? Should be four independent strips.

    Keith Thomas -

    You are very lucky you didn't cut to deep! The plastic cutter that's in the kit is the only thing I would use. Spending a few bucks on a tool is a lot cheaper than $500 for a new display!

    Please don't use a real pizza cutter!

    • Das Opening Tool hat schon den größten Teil der Arbeit erledigt, jedoch klebt der Bildschirm immer noch etwas am Gehäuse. Eine Plastikkarte ist nötig, um noch den letzten Rest an Kleber zu lösen.

    • Lege den iMac mit dem Bildschirm nach oben auf einen Tisch.

    • Beginne an der oberen rechten Seite des iMacs und schiebe eine Plastikkarte zwischen Bildschirm und Gehäuse.

    • Sei vorsichtig und stelle sicher, dass du die Karten nicht weiter als 9,5 mm in den iMac steckst. Es besteht sonst die Gefahr, Antennenkabel oder andere Komponenten zu beschädigen.

    I actually DESTROYED my display (black vertical strips) by pushing the card in a bit TOO DEEP. So it is REALLY important to insert the card only a bit (1-2mm) more than the cutter wheel, in particular at the top side, where many flat cables connect the panel with the PCB. These can be damaged very easily!

    Peter Fischer -

    Same thing with me…. Pushed cards to far…. new panel needed…€600…..

    i think ifixit needs to place a bigger caveat, as I have missed it the first time

    Edgar Broekema -

    i successfully upgraded two imacs. one opened with ifixit pizza knife and another with a regular paper knife. however, when i had to open the first one once again i broke its screen glass. it seems ifixit adhesive strips are too strong. next time i’ll try to use heater to weaken glue tension.

    Eugene Kharkov -

    I broke one too. And even if you think you did it correctly, you’ll not be able to see where you might have gone too far. You would think it’s very protected behind that metal plate, but no. Take special care with this offence to “right to repair” This should have been designed WAY better. I mean replacing a hardrive that is very likely to fail over the course of time, or even a simple desire to upgrade to an ssd!.

    Bummer

    Denis Sytmen -

    HINT: If you turn the card and use the blue part of it, then you can avoid going to deep: no further then the blue part …

    Barthold -

    On the cards I got with my iFixit kit, the blue part was way bigger than 9.5mm — closer to 20mm!

    I made a line 9mm from the edge of each of my cards and used that as a guide.

    Damian Chadwick -

    I’m thinking I might just use vinyl tape to keep the screen in place for at least a little while after an upgrade. The extra strength of the replacement tape sounds scary.

    Art Hackett -

    I wrapped two layers of vinyl electrical tape around the short side of an old gift card 3/8” from the edge. This “stop" prevented the card from going in too far. The card really helps to break the panel free.

    Paul Floro -

    This is a good tip!

    Lennart Saaf -

    Great idea! Wish I had read this before doing it. My less then optimal solution was to draw lines 3/8” around the cards, not as safe as your fix, but fast.

    Michael Piplani -

    Umm.. I’m not sure that I’d recommend using a repurposed credit card to open the display - I found that using the “pizza tool” to cut the old adhesive then using a pair of suction cups to gently pull the display up worked perfectly well.

    John Fisk -

    surely the card should have been designed such not to go further than certain distance with a barrier band.

    S Hussain -

    The cards don’t have any means to control the depth, its your skills which control it. Its no different from how you use a knife to cut your chicken up when you serve it for dinner.

    Dan -

    The pizza roller tool is enough to cut through the adhesive. You dont need to cut in a lot further. So the cards are really not necessary.

    sebastian.wittl -

    might be a stupid question but would credit cards or state ids work too?

    John Ta -

    You need the pizza cutter! The cards are used to hold the display off of the case frame.

    As for as using old credit cards and useless ID cards sure they will work. I wouldn’t use anything important ;-}

    Dan -

    No problems. I used two old credit cards and marked out a line using permanent marker so it was at the same depth as stipulated on this page. I even pushed it in a little deeper and no issues.

    • Verdrehe die Plastikkarte leicht, um den Abstand zwischen Bildschirm und Gehäuse zu vergrößern. Trenne allen Kleber in der Nähe der Ecke auf.

    • Zu viel Kraft kann das Display zerbrechen. Arbeite vorsichtig. Versuche nicht, den Spalt mehr als 6 mm breit zu machen.

    My children tend to collect cards like this from hotels, Disneyland, old IDs, iTunes cards, gift cards etc. They came in handy for this step. After wedging in the first card into the left corner, I wedged the left corner, then added cards along the bottom edge. Finally I continued to push in additional cards to existing cards and found that this created a smooth even pressure along the display top. At 2-3 card-thickness the last of the adhesive let go, gentle as a baby.

    • Schiebe die Karte in Richtung der Bildschirmmitte, um den Rest des Klebers durchzutrennen.

    was denn jetzt? Vor der Kamera aufhören, oder in Richtung Bildschirmmitte schieben, um DEN REST zu entfernen? Wenn ich vor der Kamera aufhöre, kann ich nicht alles an Kleber entfernen.

    • Hebe den Bildschirm nur einige Zentimeter an. Er ist immer noch mit dem Logic Board des iMacs mit Kabeln verbunden.

    • Wie im Bild gezeigt, inseriere die Karten zwischen Bildschirm und Gehäuse und fange an, diese leicht zu drehen, um den Abstand zwischen Gehäuse und Bildschirm zu vergrößern.

    • Wenn Teile des Bildschirms sich nicht zu lösen scheinen, dann nimm eine weitere Karte, um in diesen Bereichen den Kleber ein weiteres Mal durchzutrennen.

    • Beginne, die obere Seite des Bildschirms nach oben vom Gehäuse zu entfernen.

    I would recommend using suction cups at this stage to lift the display.

    Marco De Palma -

    I would strongly recommend using suction cups

    Luca Mucci -

    Agreed about the suction cups. An extra pair of hands might be good here as well.

    Damian Chadwick -

    I agree, I’m using iFixit suction cups right now.

    tanner85 -

    Go very slowly when lifting the display – give time for the adhesive at the bottom edge to stretch and flow. If you lift too fast, the glass can crack. That’s what happened for me.

    Gerry -

    The stickiest location on my iMac was the mid-to-lower section of the right side. There are a couple of thicker areas that needed attention from the plastic cards.

    Lennart Saaf -

    This is the step where I cracked the screen.

    HABEEB102 -

    Did you use the pizza cutter tool first?

    Dan -

    WARNING!!! This is where you can crack you screen. TAKE YOUR TIME! Everything work fine for me because I took my time. I was very shocked at how fragile the screen is. It does have a small amount of flex but don’t push your luck. There were two things that made this easy for me #1 Once you have used the cutting wheel to your best judgement to cut the adhesive, start using the iFixIt plastic cards as spacers and space them evenly around the screen. I used 10 individual cards of and gently moved them up and down at each section two at a time. Once I started having less resistance, I combined 2(i.e. 5 sets total) cards evenly space to allow for move rigid and stronger movement to separate the screen. This really helped me to free up more adhesive. #2 before lifting the screen up fully, use tweezers to pull the adhesive like a string from around the entire monitor. This will make lifting the screen much easier since all adhesive will be removed. Finally when lifting the screen use the cards with your hands under them.

    Andrew Phillips -

    Would any of you consider the possibility of heating the glass with a hot-air fan before starting the process? In that way, the adhesive would let the screen go easier, I think.

    ManuG -

    The type of tape has a lot to do with it. If the original tapes are still present then the pizza tool slices through the thin foam core of the tape so heating is not needed. If on the other hand someone replaced the tapes with just regular double sided tapes then there is no foam core to split and there is a sizable risk the display will get damaged in the process of taking it off. So sure in this case a bit of heat might help, just be aware the LCD panel area is quite close to the edge along the top three sides so you also have the risk of dating it from over heating!

    • Während du den Bildschirm mit einer Hand nach oben hältst, trenne mit der anderen Hand das Stromkabel, welches zum Bildschirm führt.

    • Hebe den Bildschirm zwar so weit an, dass du genug Platz hast, um an den Anschluss zu kommen, jedoch nicht so weit, dass du das Kabel dehnst und den Anschluss beanspruchst (~20cm).

    Mark all cable connectors with a spot of white correction fluid before removal. This will remove the risk, when reinserting them later, of getting them the wrong way round. Yes - I know they will only plug in one way round, but it does make life easier if you are not in perfect lighting!

    Alastair Lack -

    Quote - "Beware, if you’ve never done this before, that be locked out of ever being able to use an Apple repair facility, or Apple-authorized repair facility" You cannot be serious can you? So because someone attempted to repair their own Apple device that they OWN, you are saying that they may/will be locked out of using any Apple repair service again? Ridiculous claim sorry.

    The display cable, the wider one, has a lock on it , usually a plastic tape lift tab to release it, once thats flipped it should come out fairly easily, if your experiencing resistance and the cable isn’t coming out then check for this lock/latch, the power cable just pulls out, just don’t rush it everything should go fine, fairly easy to do with the end result a working iMac

    Ed tabickman -

    Is it possible to replace the power cable if its damaged? I can’t seem to find anything about this.

    Joseph Orr -

    After finishing my hard drive replacement I reconnected these connectors to test my display before using new adhesive. Everything was working beautifully. But then when I applied the new adhesive and went to seal the display on for good - the display power cable somehow became disconnected! I had to reopen the Mac for a second time which was far more difficult with new adhesive. When reinstalling double and triple check that the cables are securely inserted before the final seal. Sounds obvious but it’s quite the annoyance if something goes wrong at this point.

    azaadkb -

    Very difficult to work with these connectors.

    Power cable very difficult to unplug - data cable veeeeery difficult to plug in.

    I noticed that working with the iMac positioned vertically (and with a proper support for inclination) makes this step slightly easier…

    Luca Mucci -

    Interesting comments.. personally, I didn’t find the cables particularly difficult to detach and reattach. You do have to be patient and gentle. Personally, I found that a rolled up beach towel gently wedged between the unit and back of the display helped keep the glass up. Also, a small flashlight can be helpful to see the cables and connectors if you’re lighting isn’t perfect.

    John Fisk -

    I’d agree to John - not overly difficult. My workaround was to prep the screen for re-installation and then place it in front of the standing machine. The cables are long and flexible enough to be put in place even in this state. You can easily attach the cables and continue with fixing the screen to the housing.

    stefan -

    I would not recommend doing this step as pictured. The cable you are removing has little tabs on the wide side that can be depressed inwards towards the center of the connector, releasing the cable. If you just grab the cable as pictured and yank it out, without depressing the side tabs, you are likely to damage something. Don’t pull on the wires, use your fingernails at the connector to squeeze the very small little tabs inward to release the cable from the connector.

    maccentric -

    The removal of the LCD power cable does require the left and right sides to be squeezed inwards towards each other first before removing, why this isn’t mentioned in the take apart can lead to damaging the iMac.

    robert -

    I agree with maccentric. DO NOT just pull the power cable. Use your fingernail or spudger and gently press the tiny notch inward and towards you gently and one side will disengage. Do the same for the other side and it will slide right out. The notches just have enough edge to catch your nail or spudger. Using your nail is better as you can better feel when you have caught the edge and can feel the cable move.

    Bryan -

    First: During reassembly, I highly recommend you connect these cables and do a test boot BEFORE you remove the protective tape on the adhesive strips. That way you can fix any issues(like a damaged cable) if something is not right and you have not re-glued the screen back down which will cause a problem. If you have a second person and everything is working after test boot, you can just leave the cables connected, lift the bottom of the screen and have 2nd person pull the protective tape on the adhesive strips and you can set the screen in place. Second I damaged the video data cable during reassembly on my late 2015 iMac- I did not get the connector straight and I damaged the wires on the cable. I recommend you have someone else hold the screen while you attach the cables - they are fragile. Luckily, the data cable was easily replaced for only about $20. If you must do this by yourself, just be careful I highly recommend have 2 people at this step during reassembly.

    Chip T -

    At least on my “late 2013” model, the smaller display cable connector has tiny, tiny clips on the outside edges. These must be squeezed to unlatch it. Don't pull on the cable itself or the wires can be pulled out. Even with my small fingers, it was hard to grip the clips. When reconnecting, the connector will lightly snap into place.

    Paul Floro -

    I managed this step without any problems, but I had my wife hold the screen up while I disconnected/connected the cables. I STRONGLY encourage another pair of hands here so you can focus your full attention on being ultra careful with the cables.

    BARRY RODRIGUEZ -

    On the 2015 there are 2 cables.

    1. Once the display is loose use the Mac foam block sold from Ifixit to keep the display from rocking to hold open the glass

    2. Blow out dust with canned air

    3. Get a flash light and small flat edged screw driver

    4. Use the screw driver to slow pry loose the connector from the socket by gently inserting it in the gap on the left and then on the right slowly easing the connector from the socket towards the top of the glass

    5. The more center connector has a pull tape and a wire loop. Lift pull tape and the wire loop will raise up.

    6. Pull the wire loop towards the top of the glass to slide out the connector from its socket

    Anthony Crocker -

    Good instructions except for the screwdriver - try and use a plastic spudger instead ! Also, getting a headworn LED light makes life a bit easier.

    Philip Sedlmair -

    Have a late 2013 model and went to do the SSD upgrade. When going to remove the display we cracked the bottom left corner of the glass (just the glass frame part - not part of the screen that displays anything). We were also having difficulty putting re-attaching the display flex cable. Whenever we finally went to test it before re-sealing the screen back on with new adhesive it would sound like it is turning on as it makes boot-up noises and the fans start running, but the screen would just remain black. Just wondering if the crack in the bottom left-hand side of the glass/display would have damaged a part of the display assembly or if it would be more likely that we just damaged the display flex cable (which can be replaced for $26)?

    Dan -

    The panels are different since technology progresses at a rapid pace and Apple does like to be on bleeding edge of things. When they do a manufacturing run of screens, there will be a few years that will have the same screen. I believe 2017 is when they introduced the higher resolution panels. Everything from 2012 late to 2015 should be the same though.

    Philip Sedlmair -

    That display cable connector is common to many Macs of the 2012 era. I’ve destroyed 2 in 38 years of servicing all types of computer equipment.

    As stated, there is a latch on this connector. If you put any incorrect force on the cable or connector during disassembly or reassembly, you will break the cable and possibly the connector. The cables can be purchased online and the video connector on the display is exactly the same.

    I repeat, if you pull out on the video cable after it has been unlatched instead of parallel to the logic board, YOU WILL BREAK IT.

    Peter Haigh -

    There seems to be missing a step or two. As I was removing the old display, there are two wires that need to get transferred to the new replacement display. There is not note about these two wires located at the top of the display. The 1.128-inch ribbon cable and then this other 4-inch long, two-wire cable that goes to a very small circuit board that is 1/4 by 3/8 of an inch and seems to be adhered to the panel.I have not been able to get this cable off the old display. There is a port for it on the replacement display.

    Note: When ordering this screen, and plastic cards as noted tools, ifixit.com did not list the pizza cutter or the new replacement adhesive strips. So now I’m not sure how to get the new one on and secure.

    Todd Derek -

    Are you sure your trying to remove a late 2013 model A1419 display assembly?

    robert -

    The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

    Andrew Stephens -

    Niemals den unteren Klebestreifen mit einem scharfen Gegenstand wie Rasierklinge oder so versuchen zu trennen, davon geht die Beschichtung des Displays kaputt und man hat hässliche Streifen unten hinter dem Glas. Stattdessen lieber versuchen, das Display nach oben zu klappen und abzuziehen.

    Bas ti -

    translation from Bas Ti because this is very important:

    Never try to separate the bottom adhesive strip with a sharp object such as a razor blade or something, the coating on the display will break and you will have ugly strips at the bottom behind the glass. Instead, try to flip up and pull off the display.

    Kurt Grootjans -

    If you are just replacing the hard drive, I have found that it is quite possible to do while leaving the screen connected, making the process much easier. The amount you need to tilt the screen to access the little pull tabs at the bottom to release the screen is also sufficient to access the drive. I remove the drive while the iMac is upright. I also heat up the bottom of the screen to soften the glue and to help with the possibility of the glass cracking while doing this step.

    maccentric -

    Very dangerous! You’ll stress the cables and the logic board connectors.

    Dan -

    I meant that you can leave the bottom strip of adhesive attached; you still need to disconnect the 2 cables.

    maccentric -

    As mentioned before you can pull out the lower adhesive strip. Dont cut it or move the display up and down. This is even more dangerous. On the lower side of mac where the display glass ends is a offset. When moving the display up and down you might crack it over that offset.

    sebastian.wittl -

    When removing the adhesive from the top of the screen, be sure to start at the iSight camera location (= in the middle). If you start at an upper egde of the glass (side doesn’t matter) towards the middle, you risk removing the black background foil from the screen, which will result in ugly stripes behind the glass.

    Be extremely careful removing the LCD Temp Sensor from the rear of the screen. If you pull the wire, you run the risk of severing the metal wire from the connector but not notice it because the surrounding plastic insulation may still be intact. Use a razor blade so “shave off” the sensor under the adhesive. I just had the screen replaced by a local shop and, upon boot, the fan was running full-speed and the Mac’s speed was miserable; Excel took 30 bounces in the Dock to launch rather than the expected 4-5. Novabench showed the Mac running at 4% of its expected speed (overall). The tech examined the sensor carefully, found the broken connection, soldered it back into place, and all was fine. Note that the (partially disconnected) sensor actually showed up when I ran Macs Fan Control in an attempt to work-around this. No problem controlling the fan speed then but the iMac’s running speed was awful until the disconnected sensor wire was fixed.

    I found i didn’t need to remove the speaker nor the hard drive. In fact I managed to remove the old PSU without even removing the chin strap. However, to install the replacement PSU, I had to remove the chin strap. So I would say, remove the chin strap, but you can optionally leave the speaker and hard drive in.

    While you do not need to fully remove the screws as once you loosen them a few turns the speaker becomes free. I found that after the removal of the speaker, I turned it over and popped the screws out as this made it easier to replace it later as I could see the alignment before putting the screws back in. If not you may be off a little and you do not want to force the screw back in.

    I found it wasn't necessary to remove the speaker from the left side to remove the hard drive. You can remove the screws, and then slide it over to the left — giving more than enough room to access the hard drive.

    Robert -

    me too. don't need to remove it if you only want to change the hd

    Alber Einsten -

    Agreed, wast of time to fully remove the speaker.

    Matthew Gonzalez -

    It is difficult to remove the bottom of the speaker because it bends into the frame. Be careful to remove the power button cable, which also routes in a channel in the bottom of the speaker.

    Eric -

    easier to remove the speakers if you unscrew the front ‘chin strap’ - 6/9 phillips screws that you can see in the picture hold that aluminum piece in place

    flow in -

    Agree. This is MUCH easier to do if the support bracket along the bottom is removed first. See iMac Intel 21.5" Retina 4K Display (2017) Logic Board austauschen step 25.

    Use a P00.

    To replace it, introduce it like in the photo at the link to be able to hold the right most holes of the chassis and bracket. Replace the first screw, align the bracket to the horizontal and add the screws from right to left. Each one will bring up the next hole in the bracket close enough to screw through. Reverse those directions if you are a leftie.

    Andrew Gough -

    The trick with removing the left speaker is that you have to slide it up toward the top of the iMac (continuing to de-route the power button cable carefully as you go) to get it out from under the chin before you lift it up to remove it.

    Is the WD hard drive an Apple Special with some internal rom or other thing? Planning to put in a Seagate Firecuda 2TB. Is there some special plug or temperature sensor requirement? Seems like there is only the SATA connector. Will I encounter fast fans? (can load the software to stop that). Think it’s a swap and is “easy”.

    Macrepair SF -

    Thank you iFixit for sending a T10 with magnetic tip. You saved me!

    Ben Hannam -

    The bracket screws are T10. The screws on the left side of the SILVER hard drive itself, are T8. If you seem to need a T8, you are actually trying to remove the wrong two screws. Look immediately to the left of the hard drive & you will see the BLACK bracket frame with two screws that use T10.

    jumpoverpuddles -

    I can confirm that some models are indeed a T8 on both sides of the bracket (NOT the drive itself). I have two 2015 A1419 and one is T10, the other T8

    Two notes here:  If you are using OWC’s Thermal Sensor HDD Upgrade Cable, be sure to tuck the cable under the hard drive slightly.  You cannot allow the connector to sit near the top edge since this will not allow the monitor to sit flush with the chassis when it is reattached.  Additionally, the SATA connector does not seem to fit together as snuggly as when it was connect to the HDD, so tape or a plastic cable tie to keep the connection tight may be good insurance to prevent it from coming loose.

    If you are planning on dual booting with Windows 10, the Windows 10 installed failed when the SSD and HDD were both connected at the same time.  I had to disconnect the HDD until Windows 10 was installed.  Note: I did a fresh install on a new SSD not configured as a fusion drive.  If you are planning on doing this as well, use packing tape (or something similar) to hold the monitor in place until after installing the OSs.  Then reconnect the HDD and apply the adhesive to the monitor for a permanent seal.  Good Luck!

    Walter Hayden -

    Hi Walter, i’m looking to replace the broken fusion drive with a SSD, do i have to get the OWC’s Thermal Sensor HDD Upgrade Cable?

    Gregorio Alvarado Sahli -

    Full removal of the speaker is unnecessary - just very carefully unplug the two-conductor power button cable, which is routed through the groove along the edge of the speaker enclosure. Next, unfasten the two large torx screws holding the speaker enclosure to the chassis. Now you can easily scoot the speaker away from the drive mount - move it over just enough to reach the drive mount’s 2 torx fasteners beneath the edge of the speaker (a CM or two). There’s now enough room to easily remove and replace the drive assembly .

    clinton -

    Just wondering if the HDD 3.5 (3TB) in my 2015 27’ 5K iMac case are the ones with the temp control firmware onboard. Just got quote from Auhorised repair centre for 2x the normal price of a 3TB drive.

    This step is unnecessary. Just leave the bracket in place and set the assembly aside.

    Anthony Zimmerman -

    On Late 2015 27” iMac I found that after removing this speaker, and the Right side one, I could reach under the motherboard and squeeze and disconnect the SATA data connector with a needle-nose and then remove the SATA power connector and slide the cable out from under the logic board without removing the board. The new cable slid in from the hard drive side with little effort.

    • Trenne das Stromversorgungskabel von der Stromversorgung.

    I found this cable very difficult to disconnect, be very careful because the cable is between a black tape and it's stuck very hard to the logic board and the cable is very short and you don't have space to move and separate it from the connection! Be patient and take the time you need

    MrSchaeffer -

    I found than putting the flat end of the spudger at the center of the cable, and tilting it got the cable out without an issue.

    jimboom006 -

    I was able to use the flat end of the spudger on the sides. You can see a tiny little clip on each side. Be very gentle!

    Joseph Ashe -

    I simultaneously used the fingernails on my 2 index fingers to dislodge the tabs and continue to pull the cable out. It took a couple seconds.

    Eric -

    ultimately the trick for me was to just pull hard enough, but that part is the scariest part. any tips welcome

    Boris -

    These connectors seem pretty tough to remove until one understands the latch. Each side of the plug are two little sprung tabs (the tab is part of the spring clip which runs down the side of the plug on each side - makes sense once you see the removed plug!). Squeeze them in towards each other and then gently pull the plug from the socket. No great force, or even the spudger, needed once that is done.

    Pete Mackenzie -

    One more tip, has worked on other cables for me. Fish the skinniest spudger tip you have under the cable, and with a finger of your other hand put opposite pressure on the cable against the spudger and gently work it out

    Mike Fleming -

    If u are right handed, i can recomend to use your index left nail to press de bottom sprung, and a flat spudger on the right hand, came off so easy

    Davo Montiel -

    Davo Montiel's tip worked for me. Use the fingernail on your left index finger to press in the tab on the bottom side of the connector and with the right hand use a flat spudger to press in the tab on the top side of the connector.

    The top right screw on the power supply actually screws into a stand-off screw connected to the back of the iMac case. Once you have removed the 4 x Torx 8 or 10 screws you can move the power supply enough to see the upper face of it.

    It has a Torx 25 slot in it and comes out easily. This will give you a lot more room for your fingers in Step 40, depressing the tab on the DC power cable connector to pull it out, and when replacing it on reassembly. You may find it won’t require you removing the support bracket as in the suggestion above.

    Remember to push in the disconnect tab on the large connector. Carefully insert your finger and push on the tab before you pull on the connector.

    Manuel Collazo -

    Thank you Manuel, this was a tricky one.

    David Zemsky -

    Yes, I pulled the whole socket out because I didn’t know about the tab. Fortunately I was able to place it back in. Not sure if it was glued or how it was anchored but it seems to have a solid connection and I can’t easily pull it out by hand. Once I plug the power cable back in should be ok.

    P. Hisada -

    This connector was very difficult for me to remove (even after pushing the disconnect tab). Eventually I had to use a pair of needle nose pliers to wiggle it back and forth out of the socket. A lot of the cables on the my late 2015 model were very tight and a struggle to get out.

    Anthony Zimmerman -

    I'm struggling with this step. I presume that the tab to which you are referring is behind the connector. I can see a plastic protrusion there but it does not move when I push it. Just to get my finger behind it requires the power board to be moved quite a bit btw.

    Dave Sands -

    Pressing on the release on the back with my finger and at the same time using a needle nose pliers to wiggle the connector with my other hand worked for me.

    Kimbo M -

    i could not get it out by the force of my fingers, so what i did was slightly turn the imac 90 degrees so i could reach the area better, push up (so, vertically) the power control board, push in the tab on the bottom of the connector with my right hand, and slightly wiggle the connector out of its socket with a plier

    Boris -

    removing the chin strap (the front bit of metal running along the bottom of where the screen was) makes this much easier as you can rotate the board and get to the underside

    Dan Smith -

    The tab is a pain in the a$$$ to get your finger in there. I was so horrified at the size of the capacitors that I put on gloves to reduce any amount of shock :-) . To get it loose I would pull out carefully the power board as far as I could than I wedge my index finger under and press the tab and slowly pull until I saw a slight gap between the end of the socket and the plug. I than place the flat part of the black spudger or blue one into the gap and use as it as a wedge to help move the plug forward as I kept the tab pressed.

Then it just slides right in and then screw it down.

    • Das SATA Festplattenkabel kann im Moment noch nicht entfernt werden, wird jedoch das Entfernen des Logic Boards behindern.

    • Ziehe das Kabel und den Verbinder durch die rechte Festplattenklammer. Lege das Kabel auf die rechte Seite des iMac weg vom Abluftschacht.

    Anyone know if models that shipped with only a bladed SSD have the SATA cable still inside? I’m guessing probably not, but haven’t been able to confirm anywhere.

    Jesse Mitchell -

    The cable was so stiff, I didn’t try to pull it through the bracket. Instead I removed the upper screw holding the right HDD bracket in place. Then I rotated it counter clockwise enough to just move the cable behind it and out of the way. Once I did that, I screwed the bracket back into place. I reversed the process when I put the machine back together. It’s a Torx-10 BTW.

    Kenneth Cluff -

    Excellent tip, Kenneth! I did the same, made things easier.

    Dave Hoppenrath -

    Jesse, no SATA cable inside. My iMac came only with the blade SSD and an empty HDD bay, so I have to buy the SATA cable separately.

    the card drive cable is affixed to the heat sink with some sort of adhesive. If it is not placed back similarly, the system cannot sense the heat sink temperature, and the fan will run at full speed continuously. I used double sided tape and pushed it back in adhered position after re-attaching logic board.

    the above should read “the hard drive cable” , not card drive (typo)!

    • Drehe zwei 5,7 mm T10 Schrauben aus dem oberen Teil der Kühleröffnung.

    My model (2015) had another screw holding the heatsink duct and a stand-off holding the whole thing attached to the back. Even gently moving the logic board almost got the duct damaged till I realised what was going on so I’d suggest to be careful and DO NOT pull the logic board if it looks like it’s still attached - most likely it is!

    Carlos Ferrari -

    Ditto for the 2013 27”. One extra screw

    Dave Sands -

    My model 2546 late 2012 has 2 screws on heat sink shroud. First is on left side. The right can only be accessed with board tilted out a bit.

    Michael Wright -

    I just finished disassembling a late 2017 27” Retina and for the life of me I couldn’t get the logic board to come out. What. I discovered was that there is a part of the heat sink shroud that is held in place by a stand off boss for the power supply. You will need to remove the stand off boss using a T25. Remove carefully and save for reassembly…

    David Brix -

    Same here for late 2014.

    • Kippe die Platine leicht nach vorne.

    • Hebe die Platine nach oben und aus dem iMac heraus. Sei vorsichtig dass du an keinen Schrauben kratzt die im Gehäuseinneren hervorstehen.

    You should add a step about removing the sata cable here. When following the directions in reverse I forgot to put in back on and had to remove the motherboard again.

    Ken Prows -

    If you are having a hard time removing it, you might have forgot to remove the spacer rod when you removed all the motherboard screws. In my case, it was a T20.

    Eric -

    The 2017 iMac has a small cable with a ZIF connector coming from the bottom of the machine that needs to be detached from the logic board before it can be removed.

    greg -

    I can confirm this. As i recognized the cable after i removed the logic board i had some trouble to find the spot where to plug it in.

    sebastian.wittl -

    If you are having a hard time removing it, you might have forgot to remove the spacer rod when you removed all the motherboard screws. In my case, it was a T20. This is in my late 2015 the case. Just like Eric said 11-01-2020.

    John -

    Same for late 2012. For those curious the spacer is just to the left and appears to attach to the heat sink.

    skiingjoo -

    The iMac 27” didn’t come with the PCIe SSD card so of course there wasn’t the necessary screw to mount one.

    Here is the screw to order;

    https://www.ebay.com/itm/283482947478?ch...

    What I did was find a screw that fit. Happened to be the case screw from the iFixit external 2.5” case but since that was a countersunk screw, I fabricated a washer for it.

    • Beim späteren Zusammenbau musst du darauf achten, dass alle äusseren I/O Ports sauber in die Öffnungen passen. Die Hauptplatine könnte schief sitzen, sogar wenn alle Schrauben befestigt sind.

    • Du kannst einen USB Stecker oder ein Ethernetkabel benutzten, um den korrekten Sitz des Logis Boards zu gewährleisten während du es festschraubst.

    To help me line up the IO ports, I filled all the USB ports on the back with thumb drives before I screwed the Logic board back down. Worked like a charm!

    Alex Grayson -

    Ugh! Wish I saw this before. I did this mod and failed to do this step and now only one Thunderbolt 3 port works at a time and the SD card has to get pushed way further to get it to read. I hate taking this thing apart!

    scolvin -

    Thanks Alex :)

    iMac (Retina 5K, 27-inch, 2017) の場合、Thunderbolt 3（USB-C）ポートの位置がシビアです。

    Ethernet、USB 3ポート、Thunderbolt 3（USB-C）へ最低でも各１本（合計３本）を差し込んだままの状態でロジックボードのネジを閉めるようにすることを強くおすすめします。

    EthernetケーブルとUSBメモリの２本を挿して調整し組み上げましたが、最終的にThunderbolt 3（USB-C）が刺さらないことが後で判明し、結果組み直しをしなくてはいけませんでした。

    For iMac (Retina 5K, 27-inch, 2017), the location of the Thunderbolt 3 (USB-C) port is severe.

    It is highly recommended to close the logic board screws with at least one cable each (total of three) plugged into the Ethernet, USB 3 port, and Thunderbolt 3 (USB-C).

    I plugged in two Ethernet cables and a USB memory stick, adjusted and assembled the board, but in the end I found out later that the Thunderbolt 3 (USB-C) would not stick, so I had to reassemble the board.

    貴重な情報ありがとうございました！

    I do this job fairly frequently and I have a small box in my iMac tool kit containing a headphone jack, four USB drives, a short two-ended Thunderbolt cable and the end of a red moulded Ethernet cable to keep things aligned from the back when screwing the logic board back into place.

    I loosely screw all the screws in, then tighten them gradually, going round the board several times to make sure it lands in exactly the right position.

    • Ziehe den Verbindungsstecker der SATA Stromversorgung nach oben und trenne ihn ab.

    • Drücke auf die Sicherungslasche am SATA Datenkabelstecker und ziehe den Stecker nach oben ab.

    • Entferne das SATA Kabel vom Logic Board, damit es nicht beschädigt wird.

    Where is this cable sold

    mert -

    Is this picture correct with 7 pins? Or is it form the 5k version? (See comments on that case below).

    There is an cable on eBay with 5 pins.

    Steve Nilsen -

    This guide was written the year before the 5K model first came out. The cable in the photo is definitely for the model listed, although it’s always possible Apple made more than one variation.

    Jeff Suovanen -

    Hey, if you got this far and your iMac is getting along in years, maybe pick up a BR2032 battery and replace the PRAM battery while you’re at it, as you have to get to this point to access it.

    Tom -

    I'm waiting on the battery now! I have a CR2032 in the house, but I looked them up, and they're too different to make me comfortable using one. And I accidentally ordered the BR3032, AAAGH. Sigh. Stupid Amazon put them side by side, and I clicked on the wrong one. :) Must've been Amazon's fault. :) But for sure, I was looking at my computer in pieces, and I looked at that battery, and I thought, wait, when was this thing built? 2017? Um. Might be time for a change.

    Patrick Vickers -

    Tom, great tip on the battery. I put a new one in my 3½ year old iMac.

    Dave Hoppenrath -

    Could have used a warning that this cable is not present in models that shipped with a SSD. I was replacing my blade SSD and adding a new SSD at the same time, only to find that I was missing this cable while my iMac was in pieces. Had to reassemble it without adding the SATA SSD, major hassle.

    Matt Stamm -

    This is a bit of a grey space.

    Clearly you don’t need the cable if you are replacing the HDD or switching it out of a SSD. Its only when you are enhancing your system by adding a drive which you didn’t have before.

    Dan -

    Yeah, it's tricky on that cable. I watched a Snazzy Labs video on upgrading the i5 to an i7 (which left out lots of stuff, thank goodness for this guide and you folks), and in that video he mentioned that you might or might not find the cable inside your mac, so I went ahead and ordered one, and of course, one was in my computer, despite that it had an SSD in it. Was it because it was an upgraded SSD? I dunno. But I'm certainly sorry you had to deal with that, especially as while the difficulty isn't too high on this one, there's SO. MANY. STEPS.
    Sigh.

where the !@#$ could this damned cable be purchased?

Kaellar -

Did you ever find it? I agree with the "!@#$ "

dreamserumprod -

hi

can you tell me what is the part number of the cable please, i need one cable in order to add the second drive in ssd

rovipq -

Hi Rovipq,

I found out that the part number for the cable is: Apple No. 923-00092 for an iMac 5k late 2014 with internal SSD Drive only (No Fusion Drive!).

The cable was a while available at iFixit but I actually it's out of stock. This is really a !&&* of a work and I don't know if I can manage it so easily... Maybe I will go for the external SSD via USB :-)

G. M. -

There seem to be several genuine Apple cables on eBay at any given point. Late 2012 to current seems to work fine
