Introduzione
Removing the display on a 2012-2015 iMac 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.
Follow this guide to apply a new set of adhesive strips.
The adhesive strips come in two variants: 2012-2015 adhesives and 2012-2019 adhesives. The 2012-2015 adhesives don’t have a microphone cutout along the lower strip and should only be used for 2012-2015 iMacs.

If you are re-using your existing display, you must also remove the old adhesive from the back of the display.
-
Peel off the adhesive strips 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 the surface with 90% (or greater) isopropyl alcohol and a lint-free cloth. Wipe in one direction, not back and forth.

-
-
Lay out the adhesives strips beforehand so you won't accidentally install a strip in the wrong place:
-
Strip 11 on the top left
-
Strip 12 on the top right
-
Strip 13 on the right vertical
-
Strip 14 on the bottom right, dark side up
-
Strip 15 on the bottom left, dark side up
-
Strip 16 on the left vertical
My Strips that came are numbered altogether different. YOU NEED TO FIX THIS
Hi Stephen! I think you may have gotten the newer adhesive strips. Please see step one of this guide to determine which strips you have, and to follow the right guide for your strips.
-
-
-
Start with strip 13, which goes on the right vertical side of the rear enclosure.
-
Peel the short piece of backing off the back of the strip.
-
-
-
With the spudger still poking through the hole in the adhesive strip, push the spudger tip into the corresponding hole in the frame of the iMac.
-
Using the hole and spudger to anchor the position of the adhesive strip, line the strip up against the right edge, gently pull down against the spudger to ensure the strip is taut, and stick it onto the frame.
-
-
-
-
Work your way counter-clockwise around the perimeter of the iMac, adding three more adhesive strips in the same manner:
-
Strip 12 on the top right
-
Strip 11 on the top left
-
Strip 16 on the left vertical
-
On the iMac Intel 27" Retina 5K Display, the top-right strip's blue tabs will not line up with the top antenna in the same way as the non-5K model. This is perfectly acceptable and won't impact the performance of the strips or antenna.
-
-
-
Grasp the red pull tab on strip 14 and pull to remove the backing from the strip.
-
Align the strip on the bottom edge of the rear enclosure, directly to the right of the middle screw on that edge.
-
Run your finger along the length of the adhesive strip to ensure it is straight and unwrinkled, pressing down as you go to adhere the strip to the iMac.
Note this important point from the next step, which I believe should appear in this step as well, with respect to the right vertical adhesive..
The strip should be positioned such that the L-bend sits next to the left vertical adhesive. The L-bend should not overlap the left vertical adhesive.
Thanks for the comment! I added the note you pointed out into the step.
-
-
-
Gently set the display in place over the iMac, and align it carefully.
-
-
-
If you've already verified that your iMac is working correctly and are ready to seal it up, skip to step 18.
-
Gently insert the display data connector into its socket on the logic board. Be sure to press it straight into the socket, and insert it completely.
-
Flip the display data connector lock down onto the socket.
-
Insert the display power connector into its socket on the logic board.
-
-
-
After confirming that your iMac functions properly, disconnect the display cables and carefully lean the display forward.
-
Remove the film from the two bottom strips by reaching in from above with a pair of tweezers and pulling the blue tabs straight up from the bottom edge of the display.
This step should specify removing the film from strip 15, such that repeating the step again for strip 14 in the next step isn’t confusing. Or this step could specify both strip 14 and 15 and step 19 could be deleted entirely.
Good point! I’ll adjust the steps to implement what you suggested.
-
-
-
Repeat the previous steps to remove the protective films from all the remaining adhesive strips (labeled 11, 12, and 13).
-
-
-
To ensure a strong bond, carefully tip the iMac flat on its back (with the screen facing straight up) and press carefully but firmly around all four edges of the display.
-
Remove the tape securing the display to the rear enclosure.
Great guide. I just yesterday did my first iMac SSD upgrade and this certainly helped. The strips having glue on both sides were harder to handle than shown but then it was my first time. It’ll be easier next time. The old glue was a little more difficult to remove than suggested but after a number of years setting up I was expecting that. All things considered, this a very good and useful guide. No complaints really; nothing now days is ever 100% as it seems. Biggest lesson was don’t fear doing this. If you’re worked inside computers of any kind you very likely have the necessary skills. I wish I’d swapped the HDD for an SSD a lot sooner.
Great Guide! Just did it! :)

Great guide, thanks!
Pro tip: don’t forget to plug in the 2 cables before you close the screen.. not that I had to cut open the iMac and replace the stickers again or something :-).
