Einleitung

Diese Anleitung hilft dir die Festplatte auszutauschen oder nachzurüsten.

Bei dieser Reparatur wird in einigen Schritten beschrieben, wie du die Festplatte durch eine SSD aufrüsten kannst. Insbesondere wird gezeigt, wie der Temperatursensor der SSD installiert wird, so dass der Lüfter des iMac mit der richtigen Drehzahl arbeitet.

Bevor du am iMac arbeitest: Ziehe den Netzstecker und drücke den Einschaltknopf mindestens 10 sec lang, um die Kondensatoren des Netzteils zu entladen.

Sei sehr vorsichtig und berühre keine Anschlüsse der Kondensatoren und auch keine der offenliegenden Lötstellen auf der Rückseite der Netzplatine.

    • Befestige je einen Heavy Duty Saugheber in den beiden oberen Ecken der Glasscheibe.

    • Um die Saugheber zu befestigen, platziere sie erst mit dem beweglichen Henkel parallel zur Glasscheibe (wie im zweiten Bild gezeigt).

    • Halte den Saugheber leicht an der Scheibe und hebe den beweglichen Henkel bis er parallel mit dem anderen ist (wie im dritten Bild gezeigt).

    • Wenn deine Saugheber sich nicht befestigen lassen, reinige sie und den Bildschirm mit einem angefeuchteten, fusselfreien Tuch. (Am besten verwende destilliertes Wasser und, wenn das nicht hilft, ein 50/50-Gemisch aus weißem Essig und destilliertem Wasser.)

    • Hebe die Glasscheibe nicht nur an den Saughebern hoch, da sie dir sonst runterfällt, wenn ein Saugheber sich löst.

    • Die Originalverpackung des iMacs ist ein guter Ort, um die Glasscheibe abzulegen. Andernfalls tut es auch eine weiche und ebene Fläche, zum Beispiel ein Handtuch auf einem Tisch.

    You can easily lift the glass panel off the magnets with only your fingernails (or something thin like a credit card or a guitar pick). No need to buy suction cups you will only use once.

    Nick Caron -

    Yes, you don't need the specific suction cups to remove the display cover - it's held on by magnets, and if you start at the center by the iSight you can work out to the edges and remove it. I had an iPhone screen suction cup around and it helped with balancing the screen when you pull it out fully, but by no ways is it required.

    jtowner -

    Great guide and pretty straight forward the only thing that took me ages and I didn't manage to undo were the power btn cable (step 28) and the thermal sensor (step 25) Seemed like they were glued on! Very difficult to remove and obviously conscious so I didn't break anything!

    Eddie -

    Thanks!!! Worked excellently.

    I used a plunger (clean first ;-) to get the screen off, and http://exirion.net/ssdfanctrl/ for fan control.

    Then, i did not take out the whole display and left it in the hinges on the bottom side and held it up with two small cardboard boxes. Easy enough to disconnect the hdd then.

    I replaced with an ssd, put that into a ssd enclosure. Had to drill an extra hole in it to fasten the pins that hold it in place.

    Used Carbon Copy Cloner to make an image from the old hdd, with the sad connected via usb. Checked it of it booted via System Preferences > Startup Disk. It worked so the took the imac apart and replaced the disk. Booted, everything was working as always, only faster!

    Frank303 -

    I'm replacing my optical drive too. what exactly needs to be plugged into the SSD? I don't have the kit - as I am not sure one is required if I buy something like this: http://www.amazon.com/gp/product/B0056OB...

    Can you please advise? Can I do it with this piece, or do I need to get the entire bracket kit?

    Allen Borza -

    My display data cable forks, with a smaller section going up near the camera board. Where it forks, it is attached to the aluminum plate that attaches around the cpu board. I haven't seen any images that look similar, and I'm stumped at how to remove this second section of the cable. 2010 i7 build to order

    Awolf -

    Agree with the other comments here. Despite buying suction cups, not sure they were necessary as the screen removed very easily. A sat nav suction cup would do the job fine.

    Stuart Bloomfield -

    I can confirm that it is possible to remove the front glass using fingernails rather than suction cups. It isn’t easy, but if you try you should be able to pry off the glass.

    I did this twice: once at the beginning of the procedure and once again at the end, when I realized that a big pice of lint was trapped under the glass.

    gordonhamachi -

    Don’t use suction cups. totally unnecessary. screen pops off with fingernails.

    Kieran Hobbs -

    The reason for caution about suction cups tends to be making sure you don’t apply uneven pressure on the edges of the glass and crack it in the process of removal. I do agree however that some pretty small suction cups would do fine. These suction cups can be had at your local princess auto (Harbor freight) for a few bucks and are useful elsewhere as well. if you use your fingernails or other items just try and do it evenly :)

    Abirinder Brar -

    good duct tape or gaffer tape wrapped around your hands makes an excellent glass removal 'tool'. Even clear packing tape works a charm.

    Stu Blair -

    A great first step that minimizes that first gust of dust migration when the glass is lifted is to clean the glass, sides *and the back* before lifting the glass, and then lift SLOWLY. Most of that dust is already trapped inside and pulled up as the screen lifts, but with care you can keep it there (or gently vacuum out with a micro vac…).

    John -

    before starting any of this…there is a device that you can use that comes with the IFixit kit to format and either clone or restore your hard drive to the new drive…it will save you a lot of headaches..it is a SSD enclosure that you can plug into your existing computer …

    Tom Richter -

    Thanks for the instructions. Before doing this the first time, suggest to everyone, read through at least twice. This is the easiest step, as you’ll soon see. As for removing the glass, USE suction cups, either the ones the sell here, or others. DON’T skimp. Also wear gloves when handling the glass. Don’t take chances.

    ECJohansen -

    Duct tape works too!

    • Hebe die Glasscheibe rechtwinklig so weit vom Display weg, dass sich die metallenen Befestigungsstifte an der Unterseite der Oberkante lösen.

    • Ziehe die Glasscheibe weg von der unteren Kante des iMac und lege sie vorsichtig beiseite.

    • Trage die Glasscheibe nicht nur an den Saughebern, da sie dir sonst runterfällt, wenn ein Saugheber sich löst.

    • Löse die Saugheber, nachdem du die Glasscheibe sicher abgelegt hast, da der Unterdruck auf Dauer das Glas beschädigen kann.

    • Denk dran, den Bildschirm und die Innenseite der Glasscheibe vor dem Wiederzusammenbau sorgfältig zu putzen, da eingeschlossener Staub oder Fingerabdrücke deutlich sichtbar sind, sobald du das Display einschaltest.

    you should do this mac up, because, for me, one of the suction cup failed, and the glass fall into the lcd screen. Now there is a big hole in it...

    Lau -

    do you still have this panel?

    Alpha Dimension -

    Reassembly: After powering on and running for a few minutes, found a large whitish patch on the screen. Persists after powerdown.

    Turned out to be condensation, though it didn't look like it - more like fine white powder rubbed in. Humidity is very high this time of the year. Fix: start airconditioner in a room, leave it running a while, take iMac in, prise open the glass again. Condensation vanishes instantly. Keep it out for a ~15 minutes running infinite loops to get iMac nicely heated up and fans running. Snap glass back.

    ganesh -

    I used a Swiffer dry cloth to get all the dust off the screen while just blowing with my mouth at a steep angle. I know I didn't get every speck, but the screen looks perfect once assembled and lit again. Removing the glass from the screen is pretty easy if you need to re-clean it.

    Jay Gillibrand -

    I used a microfiber cloth instead, which worked well. The same type as yo use to clean eye glasses, but in a larger form factor.

    Daniel -

    The Swiffer idea worked great! I just brush it over the LCD and glass panel lightly, and all dust particles are gone quickly. The screen after boot up looked beautiful. Thanks!

    dtsai2 -

    I strongly recomment to detach the suction cups while working at the rest of the steps. In my case after half an our i heart a crack noise behind me on the table... The vacuum of one of the suction cups braked the glass! maybe there should be a warning in the Repair guide

    shippe -

    I didn't crack the screen, but it popped out of the shims and then popped back in, as if the glass edge is magnetic or has steel in it to connect to magnets. Be careful with this step — it is pretty nerve-wracking, but doable!

    Alex Reynolds -

    You need a big clean surface free, or at least 2 or more free surfaces because the iMac, the glass and the LCD display are quite bulky. You'll also probably need space for a tablet or a laptop to read this guide while you are working. And don't forget room to work on the optical unit and for the tools you are going to use. I covered a large table with a double layer of bubble wrap. In my opinion it's better to put the glass face down to limit powder sticking on the internal surface.

    Roberto Blandino -

    Thanks good advice! I was wondering exactly about the working space issue!

    matteoslataper -

    I am doing this repair now. After successfully lifting off the glass panel (yay!), dust blew out of the lower open edge. So I sprayed a can of air around edges. But a poof of the “air” condensated on the LCD. Does anyone know if I can clean the LCD same as how the glass is cleaned (damp cloth with equal parts white distilled vinegar/distilled water) and if not then how?

    Amy C -

    Hi Amy,

    To clean the LCD panel, I would suggest using a clean microfiber cloth and rubbing alcohol. Distilled water can be used, but avoid regular water, which contains minerals. Make sure the microfiber cloth is absolutely clean and has no hard particles sticking on the surface, which will scratch your LCD when you wipe it.

    Wet the surface with some alcohol and gently wipe with the microfiber cloth. Wipe in one direction.

    Arthur Shi -

    I find that the LCD is not as fragile as we all think. they are very much like any LCD on a tv or monitor. There is no extra glass on the front of a monitor. Not the 23 HP Pro Displays I have anyway. I know this because I punctured one moving my video wall. so I took it apart to know how its put together. I will say, there are several 'lens’ like sheets and a reflective (silver} sheets that are the same size as the panel. and a 1/8”piece of acrylic, all behind the LCD panel. Take care with them and clean as you would your monitor.

    My suggestion is to stand the iMac up after the panel is secured back into the body of the iMac and clean while its vertical. took me 3 attempts before I realized that while laying flat the surface is large and collects dust with mind blowing speed.

    Stu Blair -

    If the LCD glass is badly cracked and broken you need to be extra careful removing as the sharp shard of broken glass can scratch/harm the underlying screen as they may “fall in or onto” the screen below.

    I found that strategically putting sheets of 8x11 paper(s) under the sharpest, largest broken sections help protect the underlying screen. A vacuum was also helpful removing some of the small glass shards.

    Mark Hilliard -

    Be advised: I did a perfect replacement of the hard drive, temperature sensor to the SSD, LCD screwed in, glass cleaned. I went to put back the final glass, I set the bottom edge in place and as I slowly moved to have the magnets take hold, they pulled the screen out of my gingerly held fingers, and smacked into place……cracking the glass! Ugh! So, on this last step, hold tight as you put the glass back in slowly. It will cost you about 40-50 bucks for a new glass (mine is on it’s way).

    R R MOOS -

    Yikes... that sucks. thanks for sharing this information. I took everyone's advice and removed and placed this back very very carefully.

    iSeeU ChilinHomie -

    Don't trust the suction cups after you remove the screen cover. Used both hands to hold this piece carefully!

    • Drehe die acht T10 Torx Schrauben heraus, die das LCD am äußeren Gehäuse befestigen.

    • Fasse den Bildschirm nicht mit den Fingern an, da das Fett Rückstände darauf lassen könnte, die schwer zu beseitigen sind.

    • Mittig an der Oberkante der Displayeinheit befinden sich die EMI Dichtungen. Wenn nötig, musst du diese vorsichtig ablösen.

    The screws on the top (left-top, and right-top) are slightly longer than the other six screws.

    henryhsu -

    All screws were exactly the same for me.

    Michael Grace -

    There were only eight screws holding the lcd in place on the sides 4X4

    • Lege den iMac vorsichtig seitlich auf eine flache Oberfläche.

    • Das Display ist mit sehr wenig Spielraum eingebaut, deshalb musst du einen dünnen Haken benutzen, um ihn aus dem Gehäuse zu bekommen. Auf dem ersten Foto siehst du, dass wir dazu eine Büroklammer entsprechend gebogen haben. Eine angewinkelte Pinzette kann auch gute Dienste leisten.

    • Benutze dieses Werkzeug, um eine Seite der oberen Kante des Bildschirms an ihrem metallen Rahmen zu hochzuheben.

    • Wenn eine Seite der Oberkante des Displays etwas angehoben ist, halte sie ausserhalb des Gehäuses, während du die andere Seite ebenfalls mit dem Haken anhebst.

    • Halte den Bildschirm hoch genug, um an die Kabel zu gelangen.

    • Hebe aber die Oberkante des Bildschirms auch nicht zu hoch über das Gehäuse an, da die beiden Komponenten über verschiedene kurze Flachbandkabel immer noch verbunden sind.

    I followed the procedure in the Apple Technician Guide and it was a lot easier. Stand the iMac upright on the stand (as per normal operation) and then carefully tilt the top of the unit towards you while holding the top of the LCD. The LCD just falls forward into you hands. It is also then easier to disconnect the cables.

    iandh -

    This procedure can be VERY dangerous. Why? Because there is the possibility of a gravity disaster if you lose control of the screen and it falls before you disconnect the interface cables. I know. It happened to me. After studying the Apple directions I came to the conclusion that I would need both hands on releasing a couple go the cables and decided to tape off the screen in the open position - which I did very carefully and securely. What I did not account for was the tape not adhering. Needless to say when it came loose the screen fell and ruined the connector sockets (and my computer). This could also happen just trying to hold the screen with one hand while spudging the connectors apart with the other as well. SO. LAY THE iMAC DOWN! DO **N O T** GIVE GRAVITY THE CHANCE TO RUIN YOUR DAY like it did mine!

    Gary Kimes -

    The right side was much more stuck in place then the left

    John -

    It’s the fourth time I follow this guide, power supply, gpu and dual hd operations carried successfully and I feel and works munch more relaxed with the iMac laying horizontal on his back. I’m lifting the screen with two hooks at the same time, no torsion on the frame makes munch easier to lift it.

    Then I put in the corners two pieces (two short pencils do the job) of about 3 1/2”, 9 cm, to maintain lifted the screen while disconnecting the ribbons.

    Now the GPU I’ve changed in 2017 has lasted less than three years and here I am to change it again.

    Cesar Martin -

    After disconnecting the first ribbon you can lift the screen more than 5”, enough to access the other ribbons easily.

    Cesar Martin -

    As others have posted here, Do NOT let gravity assist you. Put the iMac on it’s back when doing the remaining steps. Also, use some type of hook to assist you in terms of lifting out the display assembly. Expect some resistance, since it does weigh a few pounds. Also, as you’ll see in the next step, you can help yourself by using something to brace it at each corner to keep it lifted. Some have suggested chop sticks, bic pens, etc. Use something approx. 4-5” in length. That will give enough clearance, and not put strain on the cables.

    ECJohansen -

    To spare a paperclip, I had better to use a good needlenose plier, catch the iron frame just near the corner, and hook up.

    Stefano Vignato -

    Used plastic spudgers as levers, one pointed to start in the corner, then two flat, working across gently. When I got to the middle and pried a bit, the top lifted all the way across, allowing access to the cable in the next step. I decided against doing this with the unit standing vertically.

    • Löse das Kabel für die Vertikalsynchronisierung in der oberen linken oberen Ecke des Bildschirms. Drücke mit der Spudgerspitze auf die Seitenlaschen des Verbinders und lasse diesen so ganz vorsichtig aus seinem Anschluss heraus wandern.

    After disconnecting the VSync cable, I was able to keep the screen wedged apart by 8" which gave me enough working room to extract and replaced the hard drive without having to remove Step 6 - 8. This resulted in a faster change out of the hard drive.

    ITSupportGuy -

    Amen brother! These are great guides, but could be improved with tips to simplify some processes. I just did the same as you, and it was quick and easy, with less chance to damage cable connections.

    Hobowan Kenobi -

    thank you for the tip. faster swap-out and less risky. cheers

    Eric -

    Totally agree. I did exactly the same. Less chance for mistakes having to do and then undo steps 6-8 and faster and easier. The whole process was shockingly simple. Sad I waited so long.

    JLTX -

    After disconnecting the first cable, I was getting ready to disconnect the second cable when I realized that the amount of opening necessary to get to the second cable, is also sufficient to get to the hard drive, so why go the extra steps. I used a wedge I had close by to very carefully keep the screen up, to enable removing the hard drive with both hands. If you are replacing the hard drive, skip to Step 11.

    Bret -

    I did this and supported the LCD with two chopsticks. Jumped right to step 11. Power supply replaced; no fuss. Great suggestion. Thanks.

    Mahlon Gumbs -

    I did this and I agree. I don’t know about the alternative (doing steps 6-8) because this is my first time doing this but it was definitely quick and “safer” than disconnecting a bunch of cables (the Vsync cable alone was scary bc it feels so fragile). Only downside is you have to replace the HDD while holding a heavy panel with one hand. That being said, there was more than enough room to get around.

    This quicker method also came in handy when I had to open it up again right after closing it because I forgot to install a piece 😂🤦🏻‍♂️

    adam -

    Once I put the tip of a very small flat-head screwdriver on the other side of the spudger tip, the connector popped out.

    Alex Reynolds -

    This is the answer :-) After 10 mins of faffing about on my own I read the manual (this) and this tip took less than 1 second to get the connector out. Thank you so much, me fellow workers were getting annoyed at my swearing.

    simonf -

    I've managed to break off the fitting in step 6 trying to remove the screen, would anyone know the part to buy or how to fix this?

    jonostainsby -

    It is very hard to detach the connector with the spudger. I tried forcing the connector out with the spudger by pushing on one side and then the other repeatedly. After several times it finally came out. A tool would be useful for this; there must be special plyers for doing this. Fingernails on either side seems most obvious, but maybe there is a downside to this ?

    Daniel -

    Rocking it back and forth with some “outward” pressure on both sides was the key. This was the only connector in this upgrade that gave me a problem.

    Stephen Genusa -

    with some confidence and mechanical inclinations this is the only cable you need to disconnect to replace the hard drive. pointer finger on one side thumb the other, pull up.

    jason kawaja -

    display propped carefully and two spudgers rocking simultaneously worked great for me to get this free.

    THEN still be careful, a small loop of tape held the cable to the back - that has to be gently pulled away to let the screen lift.

    John -

    Hi do you sell new sync cables? The little plastic piece on the end that attaches to the motherboard smashed

    Jonathan -

    Use either a spudger or a small flat head screwdriver to loosen the sides of the connector. Then use small needle nose pliers to disconnect the cable. It’s easier than trying to wedge your hand in there.

    ECJohansen -

    On the 2011 27 Inch Mac I have it doesn’t appear to have the Vertical Sync cable attached to the screen. Is that right?

    rlagden -

    Both of the cables (grey and black) popped out of the plastic connecter. Can someone tell me in which slot each cable is supposed to be pinned in ? Thanks...

    Dom -

    I broke the vsync cable removing it. Any tips on how to replace it? The wire is hair thin and I have trouble stripping even much bigger ones. I don't suppose iFixit sells a replacement?

    • In diesem Schritt gelangen deine Hände in die Nähe der offenliegenden Rückseite der Stromversorgung. Berühre nie die Rückseite der Stromversorgung, die vielen großen Kondensatoren können heftige und gefährliche Stromschläge austeilen.

    • Löse das Kabel der LED Rückbeleuchtung, indem du die Sperrklinke mit der Hand herunterdrückst und diesen in Richtung der Unterkante des Bildschirms gleiten lässt.

    Do step 7 first. The cable is much shorter and more fragile, you'll have more space to remove the other cables if that one is removed first. On my mac, the cable in step 7 was glued down and had to be freed up before I could pull the connecter out of its socket.

    maccentric -

    Just skip step 6,7,8 and 9 with this powerful tools: two bic pen holding the frame.

    Look at pictures: https://www.dropbox.com/sh/5jwam38drgcov...

    fabio4 -

    I also used two pens to hold the display panel up and I had to detach only the vertical sync cable from the display on step 5. Much easier!

    Timo Laak -

    Hello Fabio, can you please re-up the picture? It doesnt seem to be online anymore :(

    Thanx a bunch!

    Esteban Garcia -

    Good idea! I used two chopsticks as they are longer. Placed them near the corner and use one of the T10 screw's hole in the side of LCD panel to prop it up. Fit perfectly and very sturdy. This gave me plenty of space to work with the replacement.

    dtsai2 -

    I skipped step 6, 7 and 8 and were using some flip chart pens to put them between the frame and the display to make the work on the hard drive. Works great.

    Rita -

    Thanks for the tip. Works a treat!

    john -

    I don’t get how smite six can be skipped—we’re these steps renumbered at some point? How could you even lift the display if you didn’t remove the screws in step 6?

    Frank Stickney -

    With the help of an assistant, I was able to skip steps 7 - 10 to remove the hard drive. Once you remove the cable you move the forward and up. Have your assistant hold the display and you can easily remove and replace the hard drive.

    • Ziehe weiterhin in Richtung der Oberkante des Gerätes, um das Datenkabel abzulösen.

    i mess up my date zif connector is it fixable?

    LUIS -

    me too. All went well expect replace this flat cable which is tricky almost when my view is low and I've got big finger. I broke the cable end connector to motherboard but I don't know if I damaged the connector on motherboard. I'm waiting from Apple service for diagnostic.

    I would suggest on the guide to add a step to explain how sensitive is to replace this cable. iMac should lay on the back and it should have some stuff to maintain the motherboard elevated in order to insert the display port flat cable to the motherboard on a less stressful way.

    strcarlos -

    This image is 100% inaccurate. My mac has a different style connector that needed to be pinched on each side to release the cable.

    Alex Nelson -

    Its not 100% incorrect for him as this was his connector. It was only incorrect for you.

    asthomas -

    Its accurate for my Mid 2011 3.4ghz iMac so it could be different for different iMac model years.

    Chris -

    The ZIF display cable is tricky to get back in. I would suggest that this cable be the first one to be put back during reassembly. You need maximum wiggle room and visibility for this. Push in the display power cable *after* this one.

    ganesh -

    How do you get the ZIF connector back in? Some screenshot or instruction would be very helpful. I cannot get mine back in.

    Brian Bowlin -

    This is really difficult, but essentially it slides in - with no discernible click. A *slight* tug on the lever lets you know its connected. Horrible thing.

    Use the ‘bic pen’ trick and you don’t have to remove this for most things but I had to go ‘back in’ to remove the super drive. I then used the tip next down and removed this connector at the screen also and put this end back in first with no screen in the way.

    Jem Marsh -

    I found the best way for me to reinstall the ZIF cable in was to lay LCD panel on its face and gently peel the black tape on upper part of lcd to expose and remove the connector there. At this point the ribbon cable is free and you can insert the hard to align connector to the board. Set LCD into imac and connect the small push connector next to the ribbon cable on board. It was easier to see and then reconnect the cable to the upper portion of LCD and tape it back over. Reinstall other connectors etc. This way worked best on my 27" iMac as it was much easier.

    thewiseone71 -

    The is a great tip

    Jem Marsh -

    I had to replace the cable due to damage from trying to reinsert it at the logic board and I found it best to re-attach it exactly the way that thewiseone71 describes it above. If you disconnect the part at the top with the tape around it, this goes much easier and there is less of a chance of damaging the port on the logic board where it attaches at the other end. I think some photos of this port, and the way this cable goes back in would be a great addition to this tutorial. Replacing this cable would also make a great tutorial.

    lana.lawrence -

    So like everyone else, I managed to screw this up. Do you remember where you picked up the replacement, or what I should look for specifically when looking for a new one? I looked on amazon, but the label on the one I found doesn’t match what is on mine.

    Thanks!

    Jeff McConnell -

    What would be really helpful to this guide, and this image is the closest I can find in the sequence, is a quick summary of exactly where the diagnostic LEDs are on this model (and what they mean, although the latter is easily googleable). I only mention this as I believe my PSU is goosed as no LEDs are illuminated anywhere, however I can only find references to 2009 and 2010 of the similar MYs which evidently have diagnostic LEDs in a different place, hidden under tape, and I suspect numbered differently. So I can't be 100% certain!

    Mark Whitehead -

    I can see why some people are breaking the connector in step 7. You do initially pull the tab up, perpendicular to the logic board, which unlatches the connector, but then it is finally disconnected by then pulling the tab toward the top of the computer, parallel to the face of the logic board. I found it easier, after disconnecting the sync cable in step 5, to then prop up the bottom of the LCD, in order to better reach the ZIF connector, the LED backlight driver cable and the display power cable.

    randy3833 -

    I messed this bit up too. It says “pull up”. As the iMac laid flat on the table, I pulled towards the ceiling, bending the pins. It should say “pull towards the top of the machine” or something.

    I managed to straighten them out with a tweezer. Looked like a couple of pins were missing at the end, but it looks ok.

    Now I have to figure out what I have done to the temperature controller, the fans blow on full speed all the time here. :)

    Thor Hammer -

    Like others that have commented, this cable is a major PITA. I used both a headlamp to illuminate the area, and the iPhone’s Magnifier app to zoom in. The connector on the motherboard is flat, low profile and characterized by a thin narrow slot. The key to removing the cable is to slide the cable out, (after flipping that bar forward). Re-attaching the cable is the same - carefully sliding the cable into that slot, while keeping that bar pulled backward, until the cable was in place.

    For me, this was the most difficult part of the hard drive replacement. I spent more time on this than anything else.

    Thanks John, would you give a short suggestion on how to help other users to remove such a “back toward” connector to make it clearer?

    Angel -

    I broke 1 of the pins on the logic board side when reconnect. Now my iMac have no display. Not sure how to fix it.

    Need better description here with close-up photos to avoid accident like mine.

    quanghuymt -

    It’s pretty simple, using ifixit IC Extractor/Connector Puller by gripping gently and carefully the tips of the connector and pull straight up towards the HDD. You can also use a spudger and gently very slowly walk it up towards the HDD.

    Chris -

    I missed up the pins on display power cable. They are very very tiny and fragile.

    John Hill -

    Cheat on this one. Loosen the tape on the back of the display. That gives you more slack on the cable. The connector is pretty standard.

    ECJohansen -

    I could not reconnect this cable. How to put back?

    FYI...I did this fix, upgraded my mid 2011 27" to a Samsung 850 EVO SSD Hard Drive. Everything went great except for two parts...

    1. When I started up with my install media I got a three beep error and I could not install. I ended up using the CRTL-R at startup and did a network install that downloads an image of the original OS that comes with the system and allows you to install with the correct file.

    2. Hard drive fan was spinning at full speed the whole time. This was annoying to say the least. Another person on this thread commented on this and said that you had to buy a $30 piece of software to fix it, I actually found another one that is free and works quite well (http://exirion.net/ssdfanctrl/).

    There seems to be a missing step here. All the while one is removing the cables from their sockets it is supposed that the screen which is quite heavy is suspended in mid air… no, you are holding it up with one hand while doing everything single handed while in all honesty it would be nice to have both hands if for nothing else to steady your movements. So. Lets add a step. Lets figure out a solution and use some kind of prop until the screen is removable.

    • Lege das Display mit der Vorderseite nach unten auf eine glatte, weiche Unterlage.

    • Falls das Display ersetzt werden soll, müssen einige zusätzliche Komponenten vom alten auf das neue Display übertragen werden. Vergleiche die Rückseite des alten Displays mit dem Ersatzdisplay. Schaue dir alles genau an und entferne alle Kabel, Sensoren und Schaumstoffteile, die bei dem Ersatzdisplay fehlen. Befestige sie am Ersatzdisplay.

    • Falls ein Kabel unter einem Klebeband befestigt ist, entferne immer erst das Klebeband. Ziehe nicht direkt am Kabel.

    • Ist ein Kabel mit Heißkleber an dem Chassis fixiert, benutze einen erhitzten iOpener oder einen Fön, um den Kleber zu aufzuweichen . Dann kann man ein Plektrum (Opening Pick) unterhalb des Kabels entlang schieben, um es zu lösen. Ziehe niemals an den sehr empfindlichen Steckern.

    • Schiebe ein Plektrum unter die Schaumstoffteile, um sie vom Display zu lösen und ziehe sie dann vorsichtig ab. Man benötigt unter Umständen dünnes, doppelseitiges Klebeband, um sie auf dem neuen Display zu befestigen.

    In my 21.5 “ imac, there simply isnt enough room to use the plastic ssd enclosure in photo 1 if you want to screw back into the bracket as instructions advise you to do. When trying to put the screen back onto the Imac, it just wouldnt fit. So basically i did not screw in the ssd enclosure fully with the bracket, there is still room for the ssd enclosure and for all of the connections and temperature sensor if you dont screw in the bracket.

    Computer is running fine after a month or so, but i image if we end up moving the imac we should be very careful not to shakeup the SSD too much.

If you don’t first install MacOS on the SSD before installing it, you will then need to use a different computer to create a bootable USB thumbdrive with MacOS installed on it, which is not as easy as it sounds as you have to format the USB correctly, and then download the OS which can take a while if your internet connection isnt great.

The new sensor cable interferes with the reinstallation. I don’t see adequate pictures above to see how to solve the problem, other than by just letting the new enclosure sit loose in the general area, which doesn’t seem ideal. Suggestions?

    David Hercher -

    Hi David,

    The sensor cable is pretty rigid, which makes it difficult to maneuver the enclosure into place. You may need to make some tight turns on the cable. You can also try running without the sensor cable and see if the fans will work adequately without it.

Note that if you are replacing the hard drive with a non-Apple hard drive, then you will have problems with the fan running full speed constantly (see http://blog.macsales.com/10206-further-e...). Basically, you'll need to either install a $30 piece of software to control the fans or short out some wires.

jashugan -

You don´t need to short out the wires, just install the free SSD FAN CONTROL app from EXIRION.NET und you´ll be fine :D

remember after the glass, to get the aluminum front off, remove the bay for the memory upgrade on the bottom first before you remove the torx screws ans lift to access the bottom case (Between step 2 and 3)

I'm looking to replace my 3.5" HDD in my iMac (mid-2011) with a 2.5" SSD. Will I need an adapter for this?

admiralpumpkin -

Absolutly. You can buy a official one on the Apple Store. I reccommend the dual-drive (HDD & SDD) tho.

marijndepraetere -

I used the newertechnology 2,5–3,5-Adapter for 16 bucks from amazon and it fits 100 %!

Martin Schober -

There are kits that have a thermal circuit and plug between the hard drive and cables to the 3.5" drive to allow other non-apple drives to be installed and still have the fans and diagnostics function normally. No need to short or modify fan speed with software that won't adjust for temperature properly. You just attach the thermal sensor to the drive and plug it in. Usually range from $50-$80 just for the cable, I'm really shocked I can't find them available from ifixit! Just ordered one from the US source.

I successfully replaced my old 2TB HITACHI 3.5" drive (had only 50% health after 2 years left - monitored with "DriveDX") with a SEAGATE SSHD 2TB (+8GB SSD) 3.5" drive and everything works smoothly, INCLUDING TEMPERATURE AND FAN CONTROL (temperature can be read and "Macs fan control" adjusts the fan just right). I cloned my drive with "CarbinCopyCloner" before replacement and I just needed to press ALT when booting, selecting "Recovery" and point to the newly installed drive under "Restart from" (Do this if you see the folder icon with question mark)

It looks like "SSD Fan Control" http://exirion.net/ssdfanctrl/ might be an alternative to using the "OWC In-line Digital Thermal Sensor for iMac 2011 Hard Drive Upgrade"

I have replaced a few hard drives lately. But on this occasion I replaced the drive with an SSD one and the computer powers on but the screen remains blank. I have checked all the cables are attached. Tried putting the original drive back in. Still blank. any ideas anyone?

quick and easy, took me about 20 minutes to swap it out. no problems with fan speed or anything else.

FAN SPEED PROBLEM -> FIXED FOR FREE

When replacing HD with same (newer model) type and brand the fan-full-speed problem still occurred. Reason: All HD's not sold by Aplle Store don't have required special apple firmware to handle the Apple built-in fan controls. Fix: FREE program: http://www.crystalidea.com/products?ref=... Don't spend money.

OVERHEAT PROBLEM / CLICKING HD

My medio 2001 iMac heats more then box windows pc: large screen that generates heat very close to components. When you hear the HD "click click", it's safe to say your HD is running too hot. Play with settings in Mac Fan Control prog to find the "no click"-setting. Check manual HD.

SLOW MAC = HOT MAC = BURNING HARD DRIVE TOO MUCH

Macrunning slow? check available RAM in Activity Monitor. If it's less then 1 gig, by some more. Dead cheap at +- 50$ / 4 gig.

EU USERS OF IFIXIT

1) Google for iFixIt Europe to find a German based webstore.

2) Buy kit + the screwset, the screws are USA type.

It's dead easy, took me 30 min.

Good luck!

marijndepraetere -

Question for folks. I have a 3TB drive (WD Caviar Green) that is out of an Apple Time Capsule (the wireless bit died) that I was going to put into my iMac. It's got the Apple logo on it. Does anyone know if this will work without needing the cable or special software?

Wyn Davies -

I did this upgrade - Samsung 850 EVO SSD - Adaptadrive & Sensor. The computer won't start now - won't even try to start. I think that the connection at the very top left of the screen to the back might not be correct - it might be broken. How do I deal with that? I went to an authorized Apple store and they said they won't look at it because I messed with it on my own.

Theresa S -

All I had to do was disconnect the vertical sync cable. I supported the LCD with 2 Bic pens and had great access to the hard drive. There was no fan control on the HD. Everything went back together and it works perfectly. It took less than 15 minutes from start of repair to reboot.

jwlussow -

Same for me, no fan control cable, and I even bought the part and had it ready! And I agree, removing the whole panel is overkill, once you get that thin top cable detached it will lift out pretty far and gives plenty of access.

Robert J. Carr -

The Bic tip is a great move… many thanks. My third time inside mine now as I try to resolve a random restart issue - fitted OWC sensor on 2nd time in but now I’m putting the old drive back to see if it still occurs.

Going to be under there again - so much easier with the Bics

Jem Marsh -

Took an hour because I was taking my time and blew out all the nasty dust that permeated the entire inside of the nearly 4 year old iMac. Used an AdaptaDrive with an OWC thermal sensor, and a Samsung 850 EVO 1TB. Unscrewed the pins on the drive and the bracket on top and attached that hardware to the AdaptaDrive frame. Cloned the drive ahead of time and when powered up, the thing screamed to the desktop. Fans are both sitting at ~1150 RPM. So, success!

cvolek -

Added new SSD in place of HDD. I used the method without removing screen, just removing first wire and supporting it on whiteboard markers. I had to drill an extra hole in the upper bracket because it's screw holes were too far away. I used regular 5.5mm drill head, and you can swap the rubber hole inserts to the new hole. It allowed me to easily add the SSD with simple ADATA bracket I got for free with my Samsung EVO. I know you can get 'the right one', but I did with what I had.

kursisskaspars -

Thanks, this guide was PERFECT. I just installed an Intel 730 SSD and now my iMac is SCREAMING FAST. Nice tip on using the Dry Erase Markers to hold open the display so that you only have to disconnect the vertical sync cable. I used a short Torx to undo the HD. I used OWC AdaptaDrive to install the SSD. Love this website. What a great resource for the DIY crowd!

Giving birth to a flaming porcupine would be easier. Why make it so difficult? At least the memory swap is pretty simple.

I tried to install an SSD using this and several other instructions available online. All of the others did it successful and I did not. The installation on the physical drive was easy. Getting my iMac to recover is not. It doesn't respond to the recovery boot. I tried using a bootable usb drive and a fresh install of the OSX, but that froze at "one second remaining". I'm now attempting a restore from time machine, which surprisingly did start, but is so slow that it will take over 9 hours to restore (it's still increasing as I post this). Can anyone give advice?

Kryn Sporry -

Managed to succeed. Here was my situation:

My SSD was brand new and not initialised. Internet recovery wasn't possible as the iMac couldn't boot in recovery mode. I suspect this may be due to that bootable part being absent from the new SSD. Newer models may have a bootable partition in ROM, but my late 2009 iMac didn't.

I made a bootable USB drive on my MacBook Air. That allowed me to boot from the USB in recovery mode.

There I formatted the SSD.

I tried a fresh install of El Capitan, but as explained above, that failed.

I then tried booting from my time machine, which surprisingly worked. It only allows you to do a restore, so I selected the latest backup entry point (a few hours before I made the upgrade.

Restoring took about 9.5 hours, but this morning it had finished as the screensaver was on.

I logged on and it finished setting up my Mac.

The rest of the startup was a bit slower than expected, but I think it was faster than with the original drive.

Kryn Sporry -

GREAT! Replaced my HDD of a MID 2011 iMac 27" with a Crucial SSD 1 TB in 15 minutes (two people).

Performance is 100 to 1, this is really like buying a new iMac, but at 10 % of the cost.

Prior to replacing the HD I made a TimeMachine backup of my iMac and created a USB-Boot device for OS X Sierra.

After installing the SSD drive, boot up from the USB device and make a fresh install of Sierra. After this, connect your TimeMachine backup device (i used a 1 TB external USB HD) and use the Migration-Assistant from the Utilities Programs to restore the User/Apps/Data files from the Time-Machine Backup. The restore took about 5 hours (600 MB) because of USB 2.0 - so be patient.

This way you will end up with a FRESH IOS INSTALL and all your mail/settings/data/apps/fotos... from your TimeMachine Backup.

I absolutely recommend this upgrade because of the exceptional performance gains when using fotos, garage band, motion, final cut pro x, imovie - BIG SMILE!!!

...just do it!...

To get rid of the "HDD FAN PROBLEM" I installed HDD FAN CONTROLL app from EXIRION.NET. It´s free and does the job quite well!

Martin Schober -

Thanks for the instructions! :-)

I successfully swapped my iMac's original 1 TB Seagate HDD with a 2 TB Seagate SSHD and everything went smoothly. Prior to swapping the drives, I cloned my original drive to the new drive using Carbon Copy Cloner (https://bombich.com/). After I installed the new drive, my iMac booted up with no issues. I noticed my fan was running continuously so I installed the SSD FAN CONTROL app from EXIRION.NET. I ran this app and set the Hard Disk fan to SMART mode and the fan slowed down to a quiet speed.

Scott Knaub -

Replaced broken stock drive with 2TB Western Digital Gold and OWC In-Line Digital Thermal Sensor HDD Upgrade Cable for iMac 2011 (model # OWCDIDIMACHDD11) using this procedure. You definitely do not need to remove the whole screen. Just lift the top edge, remove a single cable (the vertical sync cable) and then prop the screen up on both corners - the idea of using two BIC pens worked for me. All worked fine, no fan speed issues.

Kevin Ryan -

Hi, I've three questions:

One, if one is putting in an SSD is replacing the EMI foam necessary? One, it won't touch the chassis with an SSD mounted, and, I wonder if it's only needed for spinning drives?

Two, when replacing drive and using the OWC/MacSales thermal connector cable. getting that cable tucked in inside the inner frame, it's difficult to do without dislodging the wireless antenna connection leads. Is there a trick to doing this without knocking one of these sensitive lead connectors off?

Three, the display data (ZIF) cable seems somewhat imprecise to reconnecting it. It's not a positive click or lock into place. I'm sure the metal clip that retains it needs to be pushed back down, but it's reseating seems so tenuous that I usually boot the computer up before screwing down the display, just to make sure it works. Is there any sure fire way of making sure this cable is reconnected right when putting it back together? The other cables all seat nicely and you know they are either connected or not

Here’s some “low hanging fruit” to get out of the way before considering the more mysterious possible causes. Do you have any Bluetooth input devices like a mouse, trackpads or keyboard in the vicinity of the computer? If such items are powered on, they can interfere with even wired mouse clicks. Remove their batteries and wait a few seconds and then see if your mouse works.

I just finished replacing original 1GB drive with a new 4GB one, same make, same series. By following advice given here about OWC product OWCDIDIMACHDD11 I got one despite it being ridiculously expensive. Absolutely no luck even if I followed OWC’s instructional video carefully while installing the kit. Fan blows at max regardless. Now I managed to get it sorted with Mac Fan Control app but must say that OWC’s kit is a hoax.

Followed these instructions to install a new SSD drive and it went perfectly. My only suggestion for improvement might be that steps 6-8 aren’t necessary. After removing the vertical synch cable, I was able to raise the display enough to remove the hard drive (and re-install the new SSD drive) without having to remove the cables as described in steps 6-8. My take on it is that the fewer cables I have to unplug and plug back in the smaller the opportunity for damaging something. I have not had any issues with the fan either. I dropped in a couple of 8GB sticks of memory to replace the 2GB ones that came from Apple. The new SSD drive and the memory upgrade makes for a much faster machine. Thanks for the instructions!

Daniel Adams -

I have a mid 2010 iMac. Are these instructions applicable ?

Fog Bank -

Service note: As you can replace the hard drive without disconnecting the 4 cables. Be VERY CAREFUL to put a display screw back in one place to avoid having the display to accidentally fall forward and “rip” the cables out of their connectors. This is a quick way to replace the hard drive. Also note that while other drives usually have a temperature sensor connector/cable, the original Apple 1TB does not. It only had the 2 SATA power and data cables.

Carl Schultz -

Just after buying the iMac I got it to a local Apple Dealer and replaced the default 1TB HDD with a 256GB Samsung SSD + 2TB Seagate Combo. Now the Seagate died (after 6 years, I assume this is ok). So I replaced the Combo with a current Samsung 860 500GB SSD and a WD Blue 2TB HDD. No Issues so far!

Thanks a lot for the Guide!

Some note, I do not have the suction Caps so I was able to grab the Front Glass by applying my fingernails between Glas and Aluminium Body. That worked reasonably well too.

Andreas Hoffmann -

So, I ordered a new SSD drive and a mounting kit. I took the SSD drive and cloned the complete OS onto it and used a USB dock to test. I was able to successfully boot to the SSD drive. I followed these directions and installed the drive. Everything went smoothly until I tried to boot. I get a blinking question mark. The computer does not recognize the drive inside it.

I know the drive works.

Is there a chance that the SATA cables are bad?

This guide was very easy to follow. It was kind of fun to take apart and work on a computer that wasn’t really designed for the consumer to take apart and work on, and the guide made it very easy to do so (apparently successfully - the OS is installing on the new hard drive as I type). The one thing I think could improve it would be an image of the back of the power supply that it’s so important not to touch (and maybe some additional description of its location).

The “Parts” section is missing the heat-sensor additional part.

Step 14th instructs to peel off the piece of EMI foam and specifically remind us to transfer it back to the replacement drive. OTOH, Step 19th does not mention the EMI foam at all.

Ari Tjahjawandita -

Hi Ari,

The heat-sensor should be bundled in the kit that is listed under the parts. If you bought the kit from iFixit and didn’t receive the sensor, please contact our support team!

Good catch on the EMI foam! I’m not sure how necessary the foam is, when installing a SSD. You can always approximate the location of where the foam is, and stick it onto your replacement SSD.

I still use my iMac12,1 and would like to replace the original HD for a new SSD as indicated in Step 20. Where can I find the SSD Kit to buy?

Marcos Gubiotti Gonçalves -

At the very beginning of this guide are links to the kit that comes with everything you need to replace your hard drive.

take a look at the very beginning of the guide the link takes you to a page that has everything and you can choose what size SSD you want.

Good luck it’s a very worthwhile upgrade it can bring back speedy running to your MAC!

Hi, this guide was great and I manage to get the new SSD. I created a boot drive with Catalina, plugged in my keyboard and the usb drive and started up the machine. Holding the Options button it, I did not get the boot menu - it just ends up in the flashing folder with question mark state. I have tried all the keyboard options and none of them seem to work. I do think the keyboard is registering as I got the connect to WiFi option once. Does anyone have any advice for me how to figure out what to do next to install the OS? Thanks in advance - Johan.

This model of Mac does not support Catalina :(

Would it be easier to just boot off a SD card? These computers are so old now, that it seems easier, cheaper and safer to just boot to a SD card when the internal hard drive fails.

they replacement went fine without a hitch…when I booted it up..the “chrome” was there and then first a ø. then..a folder with a ?…,.,

I was able to boot into recovery….still no hard drive to re install backup…it couldn’t see the new drive….sio after reading all these posts and realizing the new SSD might not be formatted…I checked it with disk utility in the recovery screen…it WAS unformatted…so I selected it and erased it…formatted in 2 seconds and was able to restore my latest backup…whew! hope this helps anyone

also…in the IFixit kit there was a device that I believe was there to format the new drive before putting it in…I wish had had that info..I will. repeat this in the firs comments on the instructions

Hi,

I just did this with my 2011 iMac 27-inch and all seemed to go well. It recognizes the new drive just fine. However, the display is now showing a slight halo along the edges when the display is showing something on the darker side. What did I do wrong?

I replaced the crashed drive with a 250 GB SSD ( I used a kit from OWC [https://smile.amazon.com/gp/product/B075...} and these instructions . I skipped steps 6-8 and propped the case open to remove and install the SSD (read the review from Daniel Adams on 9-7-18) and see the photo I posted. It was easier than I expected. I also purchase an anti-static mat to work on. I wasted a lot of time trying to install Mac OS High Sierra and then re-read the instructions to find out the OWC SSD hard drive came with Mac OS already installed!

Lieber Autor,

leider habe ich das Problem das nach dem Tausch von einer Seagate Barracuda 7200.12 1TB HDD auf eine SSD mit 128GB das Display schwarz bleibt. Die Kabeln sind definitiv alle angeschlossen und das Gerät läuft auch an und Bild erscheint keines. Was kann ich tun? Bitte um einen raschen Ratschlag.

Danke & liebe Grüße

Armin
