Introduzione

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.

  1. Before you begin, make sure you have the right adhesive strips:
    • Before you begin, make sure you have the right adhesive strips:

    • The 2012-2019 iMac adhesive strips have a microphone cutout and are numbered 16, 21, 22, 23, 25, and 26. They can be used on 27" iMacs from 2012-2019.

    • If your strips are numbered 11-16, follow the 2012-2015 iMac adhesive guide instead.

    • 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 iFixit cardboard service wedge.

    • Follow these assembly directions to put the service wedge together.

    • 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.

  2. 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 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.

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

  3. Lay out the adhesives strips beforehand so you won't accidentally install a strip in the wrong place: Strip 22 on the top left
    • Lay out the adhesives strips beforehand so you won't accidentally install a strip in the wrong place:

    • Strip 22 on the top left

    • Strip 23 on the top right

    • Strip 21 on the right vertical

    • Strip 25 on the bottom right, dark side facing up

    • Strip 26 on the bottom left, dark side facing up

    • Strip 16 on the left vertical

  4. Start with strip 21, which goes on the right vertical edge of the iMac frame. Before you peel off any backing, line the adhesive strip up along 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.

    • Peel the short piece of backing off the back of the strip.

  5. Insert the tip of a spudger into the hole at the end of the strip where you just removed one layer of backing. Insert the spudger from the side that still has a layer of white backing on it.

  6. 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.

  7. Once you're satisfied that the top half of the adhesive strip is neatly aligned, peel longer blue piece of backing out from behind the strip. If the top half isn't aligned properly, you can carefully peel it up and re-stick it before peeling off the lower backing strip. Be sure to use the spudger tip to anchor the top. If the top half isn't aligned properly, you can carefully peel it up and re-stick it before peeling off the lower backing strip. Be sure to use the spudger tip to anchor the top.

  8. Align the lower portion of the strip with the right edge of the frame, and stick it down. Align the lower portion of the strip with the right edge of the frame, and stick it down.
    • Align the lower portion of the strip with the right edge of the frame, and stick it down.

  9. Use your finger to smooth out the strip. Make sure it is neatly aligned with the right side of the frame and that it sits flat. Do not peel off the front adhesive backing yet.

    • Do not peel off the front adhesive backing yet.

  10. Work your way counter-clockwise around the perimeter of the iMac, adding three more adhesive strips in the same manner: Strip 23 on the top right
    • Work your way counter-clockwise around the perimeter of the iMac, adding three more adhesive strips in the same manner:

    • Strip 23 on the top right

    • Strip 22 on the top left

    • Strip 16 on the vertical left

    • 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, 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.

  11. The next few steps will show you how to install the bottom right adhesive strip (strip 25), which includes a notch that must be aligned with the microphone.

    • Read through this step and the next four steps before you attempt the procedure.

    • Grasp the red pull tab on strip 25 and pull to separate about 2 inches (5 cm) of white backing from the strip.

  12. Fold the loose white backing to a right angle and pinch the crease with your fingers. This exposes 2 inches of adhesive while folding the red tab out of the way. This exposes 2 inches of adhesive while folding the red tab out of the way.

  13. The microphone hole is the center hole flanked by two larger holes. Align the adhesive strip to the bottom edge by positioning the microphone notch over the microphone hole. If your iMac does not have a microphone hole, align the right end of the strip such that the L-bend sits next to the right vertical adhesive. The L-bend should not overlap the right vertical adhesive.

    • The adhesive tears easily. Be careful not to pull on the strip with too much force.

  16. Repeat the previous steps for the bottom left adhesive strip (strip 26), aligning and placing it along the bottom left edge of the iMac. 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.

  18. Use painter's tape or masking tape to temporarily secure the bottom edge of the display to the iMac's enclosure. The tape preserves the display's alignment, and allows you to safely swing the top edge of the display open to access the display cables.

Follow the next three steps to temporarily reconnect the display cables and boot up your iMac prior to pulling the protective film off the adhesive strips. If you've already verified that your iMac is working correctly and are ready to seal it up, skip to step 22. 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.

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…

True ! Same goes with OWC’s strips : no foam.

The only way to reopen the iMac should it be needed, is to use razor blades…
