Introdução

Removing the display requires cutting through the adhesive around the perimeter of the screen. After the adhesive is cut, it cannot be used to re-seal the display in place, so you'll need to apply a new set of adhesive strips.

    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Place an iMac service wedge in the stand to stabilize the iMac.

    • If you're using the iFixit cardboard service wedge, follow these assembly directions to put it together.

    • If you don't have an iMac service wedge, work very carefully—the display can easily fall out and break if the iMac moves unexpectedly.

  1. Before you install new adhesive strips, remove all of the old adhesive from the perimeter of the rear enclosure. If you are re-using your existing display, you must also remove the old adhesive from the back of the display.
    • Before you install new adhesive strips, remove all of the old adhesive from the perimeter of the rear enclosure.

    • If you are re-using your existing display, you must also remove the old adhesive from the back of the display.

    • Peel off the old strips of adhesive using tweezers or your fingers. Start at the bottom and peel upward towards the top of the device.

    • After all the old adhesive is removed, carefully clean off the adhesive residue with high-concentration isopropyl alcohol (90% or greater) and a lint-free cloth. Wipe in one direction, not back and forth.

    • Don't skip this step, or your new adhesive strips may not bond properly, and the display may fall out of your iMac.

  2. Your adhesive strips should have a microphone notch pre-cut in the strip labeled 4R. If your 4R strip does not contain a notch, follow this guide instead.

Good Lord, why does Apple have to make it so difficult to upgrade or repair? There comes a point where design aesthetic just isn't worth it. Magnets, like I believe older iMacs use to attach the front glass, would have made it much easier. I'll take the extra bulk any day.

amiller77 - Responder

Have you actually done the replacement? It's actually pretty easy. Apple did everything they could to make it as painless as possible: the old adhesive separates without *any* residue, it doesn't rip apart, it doesn't make a mess. Things align like magic.

True, it could be easier. Like with the old color iMac SD. But since I don't take my iMac apart every day, doing this once or maybe twice in my computer's lifetime is a small price to pay for a *really* slim and good looking device.

Daniel Mores -

I had some issues with steps 21, 22 and 23 ... the tabs would rip off. After the third one I used the plastic card to gently create some space for the strip to escape.

Daniel Mores -

Hello! Tell me, what adhesive tapes are used! Length, width, thickness? On what basis are these tapes?

Oleg - Responder

Thank you for this fantastic guide, and all of the iFixit guides! Just finished this replacement using the iFixit Adhesive Strips/iMac Opener tool combo--everything worked very well, except that the iMac Opener tool did not particularly like the broken glass area of the display, which bent the plastic of the "pizza cutter" wheel a little.

.

One bit of helpful advice is to use extreme care when placing the replacement display back into the iMac. Make sure that you do not put the display back in at too great of an angle, or there will be a very noticeable gap at the bottom, between the display glass and the iMac frame. Adhesive strips are not forgiving, and rarely give multiple chances!

IT Helper - Responder

We've revised the guide procedure and it makes positioning the screen very easy. You can drop it into place and fine-tune the position to your heart's content. :)

Jeff Suovanen -

Place some sticky tape along the lower edge of the iMac either side of Apple logo. Position screen carefully onto the lower ledge and then use the tape to hold. Tape then acts as a hinge allowing you to raise or lower screen while in the right position. I did this and also used some tape at the top so I could reconnect screen and test HDD install. Then you can hinge screen down to remove the adhesive tape backing strips in order to close up the screen for good!!

finepics - Responder

Thanks for the tip! We've added it to the guide.

Jeff Suovanen -

Somewhere between steps 2 and 3 you might want to add, that you also need to remove the old adhesive from the rear of the screen assembly

petercph - Responder

Good call! Done and done. Thanks!

Jeff Suovanen -

Just successfully upgraded one of these to an SSD using the instructions, tools and adhesive strips from iFixit. The instructions are excellent, and the iMac opener tool does a good job of cutting the adhesive to get it open.The adhesive strips in the kit are excellent - don’t even think about trying to make your own - just buy these and make your life MUCH easier. The final part of using masking tape to position the display before final sealing is very important, and works brilliantly.

Gary Pillans - Responder

I found that for steps 10 & 11, it is better to attach 4R and 4L to the glass directly by removing the blue side of the adhesive strips and placing where they fit correctly onto the glass. Then remove the red tabs just before placing the glass onto the Mac. The right-angle ends of the tape align with the corners on the glass back.

Anthony Saxton - Responder

Of course monitor won't turn on after putting it back in. Any hint?

Joao Paulo Oliveira da Costa - Responder

Joao, I had the same problem just last week. In my case, it seems I hadn’t fully inserted the video cable. I opened it up again, reset the cables, and yes, the video still works. So, open it up, order some new adhesive strips, and be *extra* careful the second time you do it.

This was the toughest part of the HD>>SSD upgrade.Removing all the gunk, and aligning the new strips took more than an hour. The rest half that! But all good now, Thanks Sam.

Stephen Babbage - Responder

Did it this morning, to replace the hhd with an ssd. Went smooth, about one hour all the job. Be patient and it works very well. Now my late 2015 Mac flies, thanks Sam!

Thank you for this easy to use guide. Only read, look the pictures and do exactly what to do and the iMac looks like before

Armin Janssen - Responder

Tolle Anleitung, vielen Dank. Ich bin sehr frog, dass es eure Seite gibt. Die Klebestreifen habe ich bei euch gekauft und sie sind sehr gut.

Stefan Fischbach - Responder

This guide is accurate and works just fine. I also have had problems with the tabs pulling off the backing making it difficult to continue. I had problems with 4L & 4R on a previous install and today with the short end of 2. I find that after 4L & 4R removal and mating the bottom, pulling all the strips off keeping the screen spaced 2” or so at the top with one hand, removing all the strips, and then setting the entire screen works best for me.

Hi

Your description does not meet reality.

FIRST

There is another thing to my kit : Number 5 was too long. About 5 mm !!! Did I get the right one ?

Then let’s start with step TWO.

When lifting up the tape from the back of the screen, on the upper side the result was not like on the sides. The tape that came off from the top was almost 10mm wide !! After cleaning I realized that there is a second black tape on the back of the monitor. On the top it is gone now, on the sides it’s still there. What do I do ?

Step THREE

My kit had transparent tape on those tips. Had I everything the wrong way round ?

Let’s go to step ELEVEN

It’s about the second photo with the final image after putting the tapes in place. Why are they all black now ? Whatever is the reason for that, one feels pretty uncertain of the whole procedure. Are both the 4-tapes really the other way round ? On my kit, the red handle would take of the thick paperlike side… ???

So. What do I do with those tapies on the back of the screen. I take them off, right ?

Hunger Lunger - Responder

You want to remove the foam adhesive, as shown in the photos, and nothing else. The wide black mylar layer you’re describing is part of the display itself and should not be removed. If it peels up by accident, carefully smooth it out and stick it back down. Yes, the 4R and 4L strips should be placed exactly as shown in the guide.

Jeff Suovanen -

The same thing happened to me except I throw away the large tape (10mm wide) from the LCD before I realized I should have kept it in place.

Nevertheless, I completed the installation and everything works great except :

1) the LCD is slightly recessed in the enclosure (no big deal)

2) there is a section on the upper left of the screen where there is a gap between the enclosure and the LCD because the adhesive did not stick well there

May the removal of the large LCD tape (10mm wide) be causing the adhesive problem on the upper left of the screen ?

If I want to redo the job to get rid of the two problems I mentioned, what would you suggest me to do ?

Patrick Deschênes -

AVOID SHOCK… just wanted to add - Even with the power cable removed during the process there is still a very strong chance of getting a belt off of the power board… These boards can hold charge for a long time. Do NOT touch the board with tweezers or your fingers when removing the 4L & 4R strips.

howard - Responder

Brilliant guide btw.

However came across a major issue which I think you should update the guide with a note warning other people.

In newer IMacs apple has repositioned the microphone to the bottom bar where the 4r &4l strips are placed. The instructions in your guides don’t mention this and the adhesive strips will cover the microphone hole resulting in a muffled microphone input. Just be careful guys.

Jamie Comerford - Responder

Great guide, kudos! Upgraded an old iMac 21.5 late-2012 (EMC 2544).

The stripes (bought with the “pizza-cutter” tool) were of the right length and shape.

One little remark on “Step 4” - “Insert the tip of a spudger into the hole …” : the hole is obstructed by clear film on both sides of the tape; the spudger can’t help with the alignment as suggested, although the film is clear and you can locate the reference hole/notch by looking-thru the clear film. Same holds true for strips 2, 1 and 5.

I found strips 4L and 4R (steps 10, 11) to be the challenging ones: start from the sides of the central screw, lay down in place the (partially peeled) portion of the tape and, while progressing, gently peel-off the portion of the tape to stick next. The lower edge of the tape almost sits on the ledge of the aluminum front part of the chassis. Never pull the tape as the peeled part is easy to stretch along its length.

On step 13, securing the bottom side of the screen with masking tape was a brilliant idea.

Many thanks!!

Dear Sam and iFixit contributors,

So many thanks for you for this tutorial !

Everything worked fine for me. I replaced my hard disk and mounted back the screen. It took me three hours but I have been patient and I spent some time contemplating the computer’s inside. The ifixit replacement kit was OK.

Cheers !
