Einleitung

Wenn du das Display deines iMac 27" Retina 5k entfernt hast, wurden dabei die Klebebefestigungen am Rand durchgeschnitten. Sie können nicht mehr verwendet werden und müssen durch einen Satz neuer Streifen ersetzt werden.

Werkzeuge

Ersatzteile

Schritt 1

Überprüfe vor Reparaturbeginn, welche Variante des Klebestreifen-Sets vor dir liegt:
Beim Klebestreifen-Set für iMacs von 2012-2019 iMac gibt es einen Ausschnitt für das Mikrofon und ist mit den Nummern 16, 21, 22, 23, 25 und 26 bezeichnet. Die Streifen können an 27 Zoll iMacs von 2012-2019 verwendet werden.
Wenn die Streifen von 11 - 16 nummeriert sind, dann folge der 2012-2015 iMac Klebestreifen-Anleitung.

Is there anything better than these self-adhesive strips?

They don’t seem as thick as the original adhesive and not as strong. As the adhesive weakens when warm, I’ve had a screen come loose within a few days of use. Luckily the user was in front of it to catch it, else we could have been looking at a very expensive repair.

Schritt 2

Wenn sich das Gelenk frei bewegen kann, ist der iMac schlecht ausbalanciert und es lässt sich schlecht an ihm arbeiten. Du kannst es, wie im Folgenden gezeigt, reparieren, es ist aber schneller und einfacher, wenn du eine iMac Reparaturhilfe aus Karton verwendest.
Baue die Reparaturhilfe mit Hilfe dieser Anleitung zusammen.
Wenn du diese Reparaturhilfe nicht verwendest, dann musst du besonders achtsam und vorsichtig sein, wenn du hinter dem Bildschirm arbeitest. Er kann leicht herausfallen und zu Bruch gehen, wenn sich der iMac unerwartet bewegt.

Schritt 3

Bevor du die Klebestreifen anbringst, musst du erst die Reste der alten Streifen vom Rand des hinteren Gehäuses entfernen.
Wenn du dein altes Display wiederverwenden willst, dann musst du auch die Kleberreste auf der Rückseite des Displays beseitigen.
Ziehe die alten Klebestreifen mit den Fingern oder einer Pinzette ab. Beginne unten und ziehe nach oben in Richtung Oberkante des Gerätes.
Reinige nach dem Entfernen aller Kleberreste die Klebestellen mit 90%igem (oder mehr) Isopropylalkohol und einem fusselfreien Tuch. Wische nur in eine Richtung, nicht vor und zurück.
Überspringe diesen Schritt nicht. Die neuen Klebestreifen haften sonst nicht gut und dein Display könnte aus dem iMac herausfallen.

The black border on the back of the screen glass appears to be painted on. When removing the foam adhesive, be careful with tools as it can scratch off the paint and that will show through when all is back together. Fingernails worked best for me; peeling the tape up slowly followed by the alcohol wipe.

Tom Pentz -

On mine the glue stuck mostly to the enclosure. It required a lot of elbow grease to get it off.

Larry -

Used a little dab of Goo Gone with a micro fiber cloth and a lot of elbow grease on the enclosure to remove the adhesive. As far as the glass side, mine was fairly clean so I just used some 70 % alcohol and was careful. Then went back over all areas with 70 % alcohol again. Was able to clean everything thoroughly. It’s tough but worth it for good adhesion. Thanks Darren S.

Darren Stewart -

Schritt 4

Lege die Klebestreifen geordnet vor dir aus, damit du keinen versehentlich an der falschen Stelle einbaust:
Streifen 22 oben links
Streifen 23 oben rechts
Streifen 21 senkrecht an der rechten Seite
Streifen 25 unten rechts, mit der dunklen Seite nach oben
Überprüfe nochmals, ob dieser Streifen wirklich den nötigen Ausschnitt für das Mikrofon hat.
Streifen 26 unten links, mit der dunklen Seite nach oben
Streifen 16 senkrecht an der linken Seite

Schritt 5

Beginne mit Streifen 21, der auf die rechte senkrechte Seite des hinteren iMac-Gehäuses kommt.
Bevor du die Schutzfolie abziehst, halte ihn passend an den Rahmen des iMac, um zu sehen, wo er angeklebt werden soll.
Ziehe den kurzen Schutzstreifen auf der Rückseite des Klebestreifens ab.

Schritt 6

Setze die Spitze eines Spudgers am Ende des Streifens dort ein, wo du eben die Schutzfolie abgezogen hast. Setze den Spudger von der Seite ein, auf der sich noch die weiße Schutzfolie befindet.

Schritt 7

Lasse die Spitze des Spudgers weiterhin im Loch des Klebestreifens, und drücke sie in das entsprechende Loch im Rahmen des iMac.
Die Spitze verankert so die Position des Streifens, positioniere ihn korrekt an der rechten Kante, ziehe vorsichtig am Spudger um den Klebestreifen zu spannen, und drücke ihn am Rahmen fest.

Schritt 8

Wenn du sicher bist, dass die obere Hälfte des Klebestreifens gut sitzt, ziehe die blaue Schutzfolie auf der Rückseite des Streifens ganz ab.
Wenn die obere Hälfte nicht richtig sitzt, kannst du sie vorsichtig wieder abziehen und erneut aufkleben, wobei du mit dem Spudgers die Position sicherst.

Schritt 9

Richte den unteren Teil des Streifens an der rechten Kante des Rahmens aus und klebe ihn fest.

Schritt 10

Glätte den Streifen mit deinem Finger. Achte darauf, dass er parallel zur rechten Kante des Rahmens ausgerichtet ist und glatt liegt.
Ziehe den Schutzstreifen auf der Vorderseite noch nicht ab!

Schritt 11

Arbeite dich gegen den Uhrzeigersinn rings um den iMac herum, und füge drei weitere Klebestreifen auf gleiche Art und Weise hinzu:
Streifen 23 oben rechts
Streifen 22 oben links
Streifen 16 senkrecht an der linken Seite
Diese drei Klebestreifen haben jeweils ein Loch an einem Ende, benutze immer das kleinere Loch, um sie präzise zu platzieren.
Beim iMac 27" Retina 5k Display passen die blauen Laschen des Streifens nicht exakt auf die obere Antenne wie beim Nicht-5K-Modell. Das ist völlig in Ordnung und hat keinerlei Einfluss auf die Funktion des Klebestreifens oder der Antenne.

2017 27”, lining up the top strips with the smaller outside holes, the tape holes at the other end did not line up with the larger holes in the case, near the camera.

ebay - 10/02/21

For the late 2012 27” iMac, strip 23 didn't line up correctly with the antenna. the antenna adhesive was a cm off from where it should have been. No biggie though.

Daniel -

I can confirm above comment - EMC 2546 Late 2012 27" iMac, strip 23 antenna does not align with adhesive.

Michael -

Schritt 12

In den nächsten Schritten wird der untere rechte Klebestreifen (Streifen 25) angebracht; er hat eine Ausbuchtung, die genau an das Mikrofon angepasst werden muss.
Lies zuerst diesen Schritt und die nachfolgenden vier durch, bevor du anfängst.
Fasse die rote Zuglasche an Streifen 25 an und ziehe ungefähr 5 cm der weißen Schutzfolie ab.

These steps instruct you to install the lower strips to the iMac frame first, as that is what Apple instructs their techs to do. If you have an iMac without a microphone hole, you can choose to install the lower strips onto the display first. Peel the blue tab instead of the red to expose the adhesive. Carefully place the adhesive along the bottom edge of the display. The L-bend on the adhesive should match the display contours.

Arthur Shi - 02/10/20

My EMC No. 2546 did not have a microphone hole, so I was confused at first. A different instructional video (https://vimeo.com/139364064) recommends placing the strips on the display instead. I installed the strips on the frame, but I reckon installation on the display glass might have been a better option, at least with no microphone hole to contend with.

Lennart Saaf - 20/10/20

Yep, no microphone hole on the late 2012 27” iMac. I followed the video but I don’t think it made anything easier.

Maybe my mistake was putting the screen back on when the frame was lying down. I was left with a mm gap on one side due to misalignment. Stand up the mac so the screen can sit on the lip and be aligned properly.

Daniel -

Je pense qu’il est possible de coller les adhésifs inférieurs légèrement plus haut que sur l’image, pour dégager 2mm afin de permettre à l’écran à l’horizontale de glisser latéralement pour faciliter l’alignement lors du remontage.

stbrille -

Schritt 13

Falte die abgelöste Schutzfolie rechtwinklig ab und drücke den Falz mit den Fingern fest.
Dadurch werden 5 cm der Klebefläche sichtbar und die rote Lasche ist nicht mehr im Weg.

I had difficulty here. The red tab wanted to pull off from the white backing.

ebay - 10/02/21

For me the white backing was not loose. I had so much difficulty trying to detach the white strip from the black one with my nail.

adrianfpommier -

Schritt 14

Die Mikrofonöffnung ist das is mittlere Loch, das von zwei größeren Löchern eingefasst wird.
Richte den Klebestreifen an der Unterkante aus, wobei du darauf achten musst, dass die Erhebung für das Mikrofon in die Ausbuchtung im Klebestreifen passt.
Wenn dein iMac keine Mikrofonöffnung hat, dann musst du das rechte Ende des Streifens so ausrichten, dass der L-förmige Knick neben dem rechten senkrechten Klebestreifen sitzt. Der L-förmige Knick darf nicht den rechten senkrechten Klebestreifen überdecken
Der Klebestreifen kann leicht reißen. Behandle den Streifen behutsam und ziehe nicht zu stark an ihm.
Wenn der Streifen korrekt ausgerichtet ist, setze die Klebefläche am linken Rand auf den iMac, so dass Position gesichert ist.

Can anyone confirm that the mic is the middle small hole as the photo in step 14 appears to show a larger hole? I ask as I don’t have the mic kit and will have to cut the kit to suit my late 2015 iMac 27 retina. Thanks.

Amuseme -

Good catch!! Yes, the mic hole is the small center hole. The step image is showing the wrong hole. I’ll upload the correct photo shortly.

Arthur Shi -

i have a late 2015 iMac 27” 5K (iMac 17,1) and I do not have a microphone along the bottom. I am confused because other people do?

R L -

The 2017 iMacs (both 21.5 and 27" models) were the first to have the microphone at the bottom. Previous models had it at the top center with the camera.

Mike Rosenberg -

Schritt 15

Ziehe die weiße Schutzfolie von der Rückseite des Streifens ab, so dass die restliche Klebefläche zum Vorschein kommt.

Schritt 16

Fahre mit den Fingern entlang des ganzen Streifens, damit er gerade und faltenfrei sitzt, drücke ihn dabei nach unten, damit er festklebt.

Schritt 17

Wiederhole die vorigen Schritte für den unteren linken Klebestreifen (Streifen 26) und platziere ihn entlang der unteren linken Kante des iMac.
Richte den Streifen so aus, dass der L-förmige Knick neben dem linken senkrechten Klebestreifen sitzt. Der L-förmige Knick darf nicht den linken senkrechten Klebestreifen überdecken
Wenn alle Streifen aufgeklebt sind, sollte der iMac so wie auf dem zweiten Bild gezeigt aussehen.

This strip is adjacent to the power supply of the iMac. Take care not to touch any part of the power supply module during this step.

Zachary Hill - 02/01/21

At this point, before proceeding, I would make sure the the power supply is fully de energized(no power cord) by holding down the power button for 30 seconds!

Schritt 18

Lege das Display vorsichtig auf seinen Platz im iMac und richte es sorgfältig aus.

Schritt 19

Nimm Maler-Klebeband und klebe die Unterkante des Displays am Gehäuse des iMac fest.
Das Klebeband soll das Display an der richtigen Stelle festhalten und ermöglicht es dir, das Display sicher aufzuklappen, so dass du von der Oberkante her an die Displaykabel gelangen kannst.

I used 2” painter’s tape to hold the display in place, but did it a little differently. With the wedge holding the iMac at an angle, I laid the display in place and felt on the sides to make sure it was centered. Then I put small strips (4-5” long) all along the sides and top, wrapping the tape around to the back of the display to hold it in place. Then tested my repair to make sure everything worked.

I had seen some comments about problems with the strips holding in place over time, so I didn’t actually install them. Instead, I’ve left the painter’s tape on mine. I’m a week or more in, and so far there’s no sign of failure to hold. I’m going to leave it this way until I decide whether or not to replace the blade and hard drive with an SSD. I find I don’t even notice the painter’s tape as I’m using my iMac.

paul -

Paul- If you haven’t made the move to SSD yet, i suggest you replace the SATA 3.5” HDD with a 2.5” SSD, and leave the blade SSD already installed in place. You can create a new Fusion Drive with the SATA SSD & stock blade SSD. This allows you to still take advantage of the blade SSD for extra RAM.

I just did this myself on my Late 2015 iMac 5K with the 2TB Fusion Drive. I swapped the dinosaur HDD for a 4TB Samsung 870 QVO 2.5” SATA SSD and my computer feels like new! better than new!

I don’t recommend replacing the blade SSD because it’s a lot more complicated and you run a real risk of damaging the logic board.

R L -

@R L I'm 99% certain that it is not possible to fuse two SSD drives (and certainly not advised). i.e. your 2.5" SATA SSD and your stock blade SSD. I'm about to replace the failing 3TB HDD in my Late-2013 iMac 27 (stock 128gb blade SSD). My plan, assuming the blade drive even mounts, is to format it and let it mount as a separate volume. It's too small to really be of any use and my understanding is the disparate speeds may actually reduce performance overall.

Kupe -

I'm 99% certain that it is not possible to fuse two SSD drives (and certainly not advised).

I have fused the stock ssd drive with a samsung evo ssd drive for years with no problems in my 2012 iMac The downside is that to do so you have to boot from a recovery disk and do pretty complicated stuff with terminal to fuse both ssd drives. Once that's done you cannot touch your fusion drive with disk utility (mac will not reboot and you will have to erase both disk and start over). The easy option is just leave both drives separated, they work just like any standard ssd drive.

David C. -

It seems to me that some emphasis could be added to this step. I had successfully upgraded my HDD to SDD, and I had confirmed the success of the upgrade by booting my iMac 5G 27 2017 to the Apple prompt. In this step 19, I did not use a sufficient, nor a strong enough masking tape to hold my monitor when I was attempting to remove the backing from the bottom adhesive strips in Step 23. When the tape let go, the monitor screen dropped, and unfortunately I still had the power and data cables connected. In the process the data cable and the power cable receptacle were damaged. I hope to recover by purchasing a new data cable. the power receptacle is still usable, perhaps with an adhesive tape piece over the connection. I found this procedure difficult.

Schritt 20

Jetzt solltest du deine Reparatur überprüfen, damit du wirklich sicher sein kannst, dass der iMac gut funktioniert, bevor du ihn wieder verschließt. In den nächsten drei Schritten wird gezeigt, wie du die Displaykabel vorläufig anschließen und den iMac starten kannst, bevor du die Schutzfolien von den Klebestreifen abziehst.
Wenn du schon überprüft hast, ob dein iMac richtig funktioniert und wieder verschlossen werden kann, dann gehe gleich zu Schritt 22 über.
Verbinde vorsichtig den Stecker des Displaydatenkabels mit seinem Anschluss auf dem Logic Board. Achte darauf, dass er gerade im Anschluss steckt und schiebe ihn ganz ein.
Klappe den Sicherungsbügel des Displaydatenkabelsteckers im Anschluss nach unten.
Stecke den Stecker des Displayversorgungskabels in seinen Anschluss auf dem Logic Board.

After I completed this repair I noticed that the fan was spinning all the time. What is going on?

Diane Radke - 13/11/20

If the fan is going constantly the thermal (temperature) sensor is likely not attached to the hard drive. It should be okay to run it like this - but it’s loud… Better to have the thermal sensor attached and configured. I bought my kit from iFixit and the sensor was wrapped in some of the paper packaging - took me a few minutes to find it.

Greg Postma - 11/12/20

I used my foam support wedge to hold open the glass side from the enclosure side. I placed in in the center to even out the weight. I used the longer areas of the wedge so more was in contact with the two parts. This freed up my hands to plug in both power and data cables. *Just be careful

Darren Stewart -

Schritt 21

Lege das Display zurück in das hintere Gehäuse des iMac.
Schalte jetzt den iMac ein und überprüfe deine Reparatur, bevor du den Computer endgültig wieder verklebst. Überprüfe wirklich alle Funktionen deines Computers und alle Bauteile, die du entfernt oder abgetrennt hattest.
Wenn du fertig bist, dann schalte den iMac aus und ziehe den Netzstecker, bevor du weiterarbeitest.

Schritt 22

Kontrolliere nochmals, dass der iMac ausgeschaltet ist und der Netzstecker gezogen ist.
Wenn alle Funktionen des iMacs in Ordnung sind, dann löse die Displaykabel und klappe das Display vorsichtig nach vorne.
Entferne den Schutzfilm von den beiden unteren Streifen, indem du von oben her mit einer Pinzette hineingreifst und die blauen Laschen gerade von der Unterkante des Displays nach oben ziehst.

Here's a sure fire way to replace the LCD onto the frame. It involves using painters tape, a foam wedge and 12" Surgical Hemostat Forceps clamps. iMac is upright on a low table so I can look down into it, painters tape applied, Foam wedge keeps it at an upward tilting angle. Headlamp recommended. LCD and power display connectors have been re-attached. Carefully open the LCD from the frame, keep in mind that the 2 cables give you about 2" of space to "look down" and with your 12" locking forceps grab and lock onto the blue tabs, getting a good, firm bite and then pull upwards to detach from the bottom adhesive strips. There will be 2 of them. The pull tab may detach but not difficult to find the transparent thread to continue the pulling. When both sides have films removed, let the display rest back on the frame and plug it in. If boot screen you can then carefully again separate the LCD slightly to then easily pull off the rest of the strips. Reseal and I use 6 pressure clamps on all sides to cure.

Macrepair SF -

Schritt 23

Verbinde zum letzten Mal die Versorgungs- und Datenkabel des Displays.
Denke dran, die metallene Halteklammer am Displaydatenkabel zu befestigen.

Darren Stewart -

Schritt 24

Überprüfe die Glasscheibe direkt an der Kamera auf Staub oder andere Verunreinigungen. Beseitige sie, falls nötig, mit einem Mikrofastertuch, bevor du das Display verklebst.
Stütze in den folgenden Schritten das Display beim Entfernen der Schutzfilms mit einer Hand ab, oder lehne das Display leicht gegen das hintere Gehäuse des iMacs.

Schritt 25

Entferne eine Seite des Schutzfilms vom oberen linken Streifen, indem du die Zuglasche direkt nach oben ziehst.

Schritt 26

Entferne die andere Seite des Schutzfilms vom oberen linken Streifen.

Schritt 27

Wiederhole die vorherigen Schritte und entferne die Schutzfolien von allen restlichen Klebestreifen.

When pulling the adhesive strips off I had one snap in half right (just the white part revealing the adhesive) one my top right corner. I panicked because there was not adhesive there so I pulled a quick maneuver. I slipped in one of the guitar pick type triangles near the gap quickly before the adhesive has set in and was then able to slip my bent nose tweezers in and grab the white tape and peal the remaining. Whew! It worked. *Just be careful

Darren Stewart -

Schritt 28

Damit der Kleber gut hält, musst du den iMac flach auf seine Rückseite legen (mit dem Bildschirm nach oben) und sorgfältig, aber fest auf alle vier Kanten des Displays drücken.
Entferne das Klebeband, welches das Display am hinteren Gehäuse befestigt.
Überprüfe nochmals nach 24 Stunden, ob das Display sich nicht vom iMac abgelöst hat.

Before lowering the glass display, I would recommend removing the tape from the edges, in order to check that the glass is seated flush against the bottom shelf of the frame. In my case, the glass got slightly out of alignment with all the lifting and lowering of the display, and I ended up with one corner being about 1 mm above the frame ledge. Not a huge error, but regrettable, as once you start to lower the display with all adhesive exposed, there is no turning back!

Lennart Saaf - 20/10/20

A big +1 to this. I had the same issue but was able to adjust the monitor before it was fully set. Hopefully the guide can be updated with this suggestion!

I also did 1 more power on check after removing the screen after pulling the bottom strips covers off.

Don Rhodes -

Has anyone had the display fall out after a few days of use when the machine warms up and the adhesive softens?

How do we prevent that from happening?

Is it just my imagination or are the replacement adhesive strips thinner than the Apple originals? After cutting the original adhesive we are left with a thin layer on the frame AND a thin layer on the back of the front glass. To me it feels like the replacement tape is only as thick as one of these layers, so there’s less flex to take up any minor variations in level and ultimately a weaker join.

I also have no idea if the replacement adhesive retains its grab strength once the machine warms up in use.

Cool_Breeze -

I'm an (unauthorized) Apple computer tech and have replaced over 24 displays on 21.5 and 27" iMacs. The only time I had a display fall off was when I tried using GooGone to remove the adhesive residue. It leaves a greasy residue that is hard to remove and will prevent proper adhesion of the replacement strips. My customer found that her 27" display had fallen off TWICE (both times it miraculously ended up on their office chair with no damage). I now use 91% IPA and the flat edge of a new spudger tool to remove residue. Never had a problem since.

I've used several different makes of strips purchased via amazon and they all work fine.

Corey Matsumoto -

I have the same problem. I followed the instructions exactly, after gluing the display I let the iMac lie on its back for 24 hours.

Then I tilted the iMac forward and after 2 days the display started to peel off.

What needs to be done so that the display does not come off? Ambient temperature? Or is it necessary to heat the display somehow after gluing the display?

Ondrej -

Corey, could I ask you a question? Have you successfully removed a display after it has been attached using the aftermarket adhesive strips? I didn't have a problem removing the original display adhesive, but when I decided to reopen my iMac to upgrade the SSD, I had a very difficult time, which ended up breaking the screen...Thanks very much

This guide works great. Replaced a 2015 IMAC 27" screen without any difficulty especially since I purchased the Ifixit tape kit and removal tools. Thanks guys and gals. Couldn't do it without you.

gordywat - 22/12/15

will this work on late 2015 27"5k iMac

ffjones54 - 15/05/16

Hello, I got a Late 2015 iMac 5K, are the stripes the same?

filmore - 06/07/16

yes .it works

Walter Fontes - 08/12/17

Yes this adhesive strip replacement kit works for the Late 2015 Retina 5K iMac. As mentioned in step 8, the tabs for strip 12 won't line up exactly the same as shown in the guide but it does not matter. It still works and will not interfere with that antenna.

smudge - 16/08/16

Does this work with iMac 27 2017?

macdeutsche - 16/12/17

Used these guides to replace the cpu and ssd’s in my 2015 iMac 27”. Super easy! And yes with a late 2015 model, the cpu is replaceable with a regular Skylake cpu. I bought a 3.2 i5 model and replaced with a 6700K ! And yes these also take 64GB of DDR3. For the PCIE SSD you can get an adapter off of ebay…look for m.2 to iMac adapter…since they’re cheap I recommend getting like 2-3 and figuring out which one works best with your m.2 ssd. So yeah, you can get a 1TB m.2 AND a 1TB 2.5” ssd in this and have a nice little box for peanuts.

Michael Stram - 04/01/18

Friends! This manual and accessories are compatible with the iMac 27 5K 2017?

Anton Gudzuman - 18/01/18

Hi,

I done all of the above on my 2017 27inch iMac and now my microphone won’t work, when I tap the enclosure it reacts but it doesn’t hear my voice commands. Maybe the adhesive tape got stuck on the microphone somehow. where is the microphone located exactly? Help please……

Best regards, Henk

Henk - 25/03/18

I have the same problem. Were you able to fix it?

Andrew Blackman - 08/11/18

I know this is an old question, but I wanted to post a followup so hopefully, no one else makes this mistake. The microphone is located on the lower edge. Here’s the thread that covers this better. Microphone very muffled after sealing up iMac

veenenen - 11/06/20

ottimo complimenti per i dettagli

guida superlativa e precisa grazie del vostro aiuto

gennariello1966@gmail.com - 10/08/18

I did it! Be very careful when you place the tape at the bottom of the screen. The screen can fall off! Also important to keep the imac standing and not laying on it’s back because it will make it hard to remove the bottom adhesives.

Jonathan Meson - 26/09/18

After following to the letter, the screen came off and went back on just fine. 5 days later (while setting in a cool environment) the screen just came unstuck and fell out sometime during the night, Of course it tore the two cables badly in addition to the antenna wires that must have gotten in the way somehow. Took most all day, but was able to the wifi and bluetooth wires back in place and the power cable (4 connector) plug back in. The hardest part was the ribbon cable. With high magnification hood on, was finally able to get it back in it’s socket. Had to tape it down to the rest of the board so it would stay. Used new sealant strips, then CLAMPED with spring clamps (around 12 of um) then laid it flat, screen up, then put it near a baseboard heater for two hours. Temp gun was around 100* all around it. Hopefully that won’t happen again!!

avflyguy - 21/02/19

Excellent write up. Also, the detailed photos were super helpful in seeing the alignment.

The only hiccup I had was trying to remove the final tabs from strip 15 and 14 while the glass was blue taped down. I had to lift the weight of the glass panel off of the tab strips before they came off. Aside from that, a very smooth install, and very quality product. Thanks!

Jonathan Daiello - 07/08/19

Excellent guide. Many thanks.

jhlincoln - 02/02/20

Make sure you totally clean both surfaces. The back of the display can be a real pain. I know someone who told me he replaced the PCI SSD and it all went smooth (same thing I did plus a SATA SSD and new thermal paste) but a few weeks later to his HORROR the 5k display was smashed on his office floor. Make sure to really clean and press on all sides. Keeping some painters tape on the top corners wouldn’t hurt either for a few weeks to make sure it seats well.

Brian Peixinho - 11/02/20

Thank you! Just completed this after an SSD upgrade to my 2015 iMac. Much appreciated Sam!

Kaiser Soze - 17/06/20

would be REALLY nice to have this linked on every single repair page. there was NO MENTION of replacing the adhesive strips at the end of the hard drive replacement guide, and i am now staring at a smashed LCD display that will set me back $600 to replace. very frustrating as I usually love ifixit guides. please consider adding a heavily red-flagged link to this guide and information to every guide that requires removing the display.

Coleman Howard - 10/07/20

This was a super useful guide that formed the closing stage of repairing my old iMac 27” (late 2012). I replaced the power supply and upgraded to an SSD. Thank you so much for taking the time to prepare and improve these guides. They are invaluable and enabling.

Nickie Daniel - 12/07/20

very good - thank you

manxman - 26/12/20

Se me acaba de despegar a las 4 semanas de haberlo utilizado.

Miquel Vera Pedrosa - 26/12/20

Works it in an iMac18,3?

javier - 04/05/21

These instructions add a couple of steps that a well-known Mac accessory vendor's instructional video lacks: taping the screen closed to allow functional testing before you seal the adhesive, the upright positioning using the wedge, that makes it easier to set the bottom edge of the screen fully against the frame, and cleaning the backside of the camera opening before you close it up. All of these are valuable refinements.
