Introduction

Removing the display on a Late 2013 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 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. Repairs can be completed as shown, but are faster and easier with an iMac service wedge.

    • If you are not using an iMac service wedge, be very careful when installing and working behind the display—it can easily fall out and break if the iMac moves unexpectedly.

    I found that using a couple of paperbacks (one larger than the other) performed the same function - taller one placed to the rear of the stand and the other one in front accommodated the curvature perfectly.

  1. Before you start placing strips, remove all of the old adhesive from around 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 start placing strips, remove all of the old adhesive from around 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 the area under the adhesive with 90% (or greater) isopropyl alcohol 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.

    I've done this on several iMacs now, but today I noticed another layer of thin black plastic stuck to the back of the display.

    It was really tough to remove and left a lot of clear, sticky goop under it.

    It's really thin, but it was strong enough to hold the screen in place by itself - I reconnected the display cables and tested before pulling the backing off the new adhesive strips - and it stuck together!

    I had to pry it apart again and it actually ripped my new glue strips in 2 or 3 places. I was able to still use them, but it did not go as smoothly as other iMacs I've upgraded. Everything was fine in the end, but I left some blue painters tape on the top of the screen overnight so the glue strips will set up without the screen falling off - just to be on the safe side.

    Does anyone know if this last layer of black plastic on the screen should be removed or left in place when replacing the glue strips?

    That Black layer of plastic should not be removed. I found that on some segments, upon peeling back old adhesive remnants, the thin black plastic layer would also begin to peel off. STOP and cut off what has been removed, separate the black plastic strip from the adhesive remnant you are peeling off. The continue removing remnants.

    Are you sure that you’re not supposed to pull the black backing all the way off? I removed all the black strips before getting to this step.

    IMHO: The rubbing alcohol is clutch for this step. There’s plenty of residue after pulling up the old adhesive and the 99% Isopropyl Alcohol really took the tacky remnants off.

  2. Start with strip 13, which goes on the right vertical side of the rear enclosure. Before peeling off any backing, line it up against the frame of the iMac to get an idea of where it goes. Peel the short piece of backing off the back of the strip.

    • Work your way around the perimeter of the iMac, adding three more adhesive strips in the same manner.

    • Working counter-clockwise from strip 13, place:

    • strip 12 on the top right

    • strip 11 on the top left

    • strip 16 on the left vertical

    • These three strips have a hole at each end—always use the smaller hole for alignment for more precise placement.

    • On the iMac Intel 27" Retina 5K Display, strip 12's blue tabs will not line up with the top antenna in the same way as the regular model. This is perfectly acceptable and won't impact the performance of the strips or antenna.

  10. The two remaining strips (14 and 15) do not have guide holes and are more difficult to place than the previous ones. Before sticking them down, we recommend first setting them in their respective places on the iMac to get comfortable with their placement. Grasp the red film pull tab on the 14 adhesive strip 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.

    Using iFixIt’s adhesive strips, i cannot strip off the white backing. Pulling on the tab pulls the wrong backing off, the black backing. I can:t figure a way to do this correctly!

    Same with mine, but carefully using a razor blade to separate the white side from the adhesive, leaving the clear side attached, then remove the white side and place accordingly.

    The video shows the correct method - attach these strips to the back of the screen rather than the iMac itself.

    You've really got to pay particular attention to exactly where to stick these - especially the short right-angle part as it doesn't go on the back of the glass as you might expect but actually over part of the edge of the LCD. It's also really difficult to remove and reposition the stickers since they will stretch when pulling them off.

Step 14: iFixit... you're kind of missing the point of the blue tabs here. Set the mac upright and peel off the bottom strips on the lcd but keep the adhesive backing on the strips on the case. Put the LCD on the bottom lip but rest it so the adhesive isn't or is barely making contact. Tilt the lcd out towards you and reach in and down to reconnect the cables. Make sure the bottom sides are aligned properly and push the panel in place. When you're ready, pull the blue tabs out from the sides to pull the backing off, this will make an instant seal with the glass. This way it makes it much easier to align, you don't have to worry about having a gap at the bottom since the weight of the glass will make it sit flush with the lip, and before you pull the tabs, you have one last chance to test it and hinge the panel forward to get back inside in case something isn't working.

Yeah, thanks Jesse! I wish I had read your post before finishing, because that would've been a whole lot easier! Apparently iFixIt thanks you, but ignores your suggestion and doesn't update the guides!

Is there any reason to believe that Apple would deny any warranty repairs due to these adhesive strips not being identical to Apple's? I'd like to open and clean my iMac before taking it in to have the display replaced under warranty, but the vibes I'm getting from Apple support suggest that Apple may deny me service if the adhesive strips 'show any signs of tampering', i.e., being replaced for any reason. This sounds silly to me, as it doesn't void Apple's warranty to upgrade my hard drive.

Unfortunately, these strips are not even close to the original ones. Has anyone tried to reopen the iMac with these strips in place? A real pain… The original one must have a sort of foam in-between so that one can cut through with the ifixit wheel or a knife. After that, it is easy to remove the adhesive swipes on both sides. Trying to reopen an iMac with the iFixit strips in place is really hard and impossible with the iFixit wheel. Sad…
