Инструмент, используемый на этом этапе:iMac Intel 21.5" Cardboard Service Wedge$4.99
-
Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.
-
-
-
Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear enclosure.
-
-
-
Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.
-
Run the tool up along the left side of the display.
-
-
Инструмент, используемый на этом этапе:Plastic Cards$2.99
-
Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.
-
-
-
Gently twist the plastic card sideways to create a gap between the display and frame.
-
Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4".
-
-
-
Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.
-
-
-
Wedge the plastic card into the top right corner once again, and leave it there to prevent the adhesive from resticking.
-
-
-
Insert a second plastic card into the gap between the display and frame near the top left corner of the iMac.
-
-
-
Gently twist the card upward, slightly increasing the space between the display and frame.
-
-
-
Slide the plastic card toward the center, again stopping just before the iSight camera.
-
-
-
With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case.
-
Begin to lift the top of the display up from the frame.
-
-
-
While holding the display up with one hand, use the other hand to unplug the display power cable.
-
-
-
Use the tip of a spudger to flip up the metal retaining bracket on the display data cable.
-
Carefully pull the display data cable from its socket on the logic board.

Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.
-
Repeat this step with the other adhesive strip and remove it.
-
-
-
Lift the display up from the frame and remove it from the iMac.
-
It may be necessary to slowly lift from one side, to peel against the remaining adhesive.

I put off replacing my hdd with an ssd on my late 2013 iMac because it looked a bit tricky. This guide and an iMac opening tool made the job really strait-forward. Just be gentle and patient and the screen comes off with very little bother. Thanks ifixit!
Used this and the adhesive guide to replace the cracked display on a relative’s 21.5 inch iMac. Thank you, iFixit! These guides and the toolkit I purchased from iFixit years ago have saved me roughly $200.00 vs. having a repair shop do it. I still have a 2008 24inch iMac up and running thanks to this website!
I used this guide and successfully replaced the stock HDD with a Crucial 1TB SDD MX500 and upgraded the RAM to 16GB, blew out all the internal dust and now it runs beautifully and didn’t have to buy an entirely new iMac.
