    • 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 case.

    • The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert it no more than 3/8" (9.5 mm) into the display. You risk severing antenna cables and causing serious damage if you insert the tool too far.

    • Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.

    • Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle.

    • Run the tool up along the left side of the display.

    • Continue along the top of the display.

    • You may want to run the tool back and forth through what you've already cut a few times, to ensure you get as much of the adhesive separated as possible.

    • Finish pushing the opening tool to the bottom of the right side of the display.

    • While the opening tool did the lion's share of the work, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive.

    • Set the iMac face-up on a table.

    • Starting from the top right corner of the iMac, insert a plastic card between the display and frame.

    • Be careful not to insert it more than 3/8" (9.5 mm), or you may damage internal components.

    • Gently twist the plastic card to open the space between the display and frame, and cut any remaining adhesive near the corner.

    • Using too much force will crack the glass. Work carefully, and don't try to create a gap any larger than about 1/4" (6 mm).

    • Be sure to stop cutting before the iSight camera in this step, or you may damage it.

    • Slide the card toward the center of the display, to cut any remaining adhesive.

    • Put the card into the corner again and let it stay there to keep the adhesive from resettling.

    • Gently twist the card, slightly increasing the space between the display and frame.

    • As with the other side, move slowly to allow the adhesive to break, and be careful not to over-stress the display glass.

    • With the cards inserted as shown near the corners, gently twist the cards to increase the gap between display and case.

    • If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the adhesive in the problem area.

    • Begin to lift the top of the display up from the frame.

    • Only lift the display a few inches—it is still attached to the iMac by data and power cables.

  19. iMac 27" 2017 Blade SSD Replacement, Disconnect the display cables: crwdns2935265:019crwdnd2935265:01crwdnd2935265:02crwdne2935265:0 iMac 27" 2017 Blade SSD Replacement, Disconnect the display cables: crwdns2935265:019crwdnd2935265:02crwdnd2935265:02crwdne2935265:0
    • While holding the display up with one hand, use the other to unplug the display power cable.

    • Flip up the metal retaining bracket on the display data cable.

    • Disconnect the display data cable.

    • This is a delicate connection that can easily be broken. Be sure to pull the display data cable connector straight out of its socket, toward the top of the iMac.

    • Lift the display up to a near-vertical position.

    • At this point there is still a strip of adhesive along the bottom of the display that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.

  22. iMac 27" 2017 Blade SSD Replacement, Remove the remaining adhesive: crwdns2935265:022crwdnd2935265:01crwdnd2935265:03crwdne2935265:0 iMac 27" 2017 Blade SSD Replacement, Remove the remaining adhesive: crwdns2935265:022crwdnd2935265:02crwdnd2935265:03crwdne2935265:0 iMac 27" 2017 Blade SSD Replacement, Remove the remaining adhesive: crwdns2935265:022crwdnd2935265:03crwdnd2935265:03crwdne2935265:0
    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).

    • 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.

    • If either adhesive strip breaks before it's removed, use a plastic card to slice through the remaining adhesive.

    • Be very careful handling the display—it's big, heavy, and made of glass. The display has fragile edges. Avoid lifting the display by the corners.

    • Lift the display up from the frame and remove it from the iMac. Lay the display face down on a flat, soft surface.

    • It may be necessary to slowly lift from one side, to peel against the remaining adhesive.

    • After the adhesive is cut, it cannot be used to re-seal the display in place. Follow this guide when your repair is complete to replace the adhesive strips that secure the display to the rear enclosure.

is there any way to replace the I.O without swapping the motherboard?

From cutting through the adhesive to the smoke test this was just under a four hour job for me. One adhesive strip left a complete layer of glue on one side of the screen, and it took me the better part of an hour, about half my supply of wipes, and a plastic razor blade just to clean that one edge up. I’d break the time down as: removing, cleaning, or reapplying adhesives, 2 hours; non-adhesive disassembly, 50 minutes; reassembly, 40 minutes; “oh crap, where’s that tool?” 15 minutes; and about 10 minutes for cleanup, including vacuuming out the fan, heat sink, and vents.

Hi there, I need your professional help. I followed all instructions to change my iMac 2017 27" 5K fusion drive with a Samsung EVO 970 PLUS 2TB (with upgraded firmware) for macOS bootable drive and extra EVO 860 SSD 4TB data drive. Then updated to Monterey. My first test was 1200w 2900r, which was different from the youtube video which was roughly 3Krw. Why was that? Then after a few days of work, the mac froze during youtube watch and again during excel spreadsheet, and restarted with a "?" in a folder. I made an online hardware check all OK, then performed first aid, and again all OK. Then rebooted to the same "?" screen. And then rebooted again and now it works. So far! I see in the system prefs - Link Width x1. I made the speed test again and the reading now is roughly 700rw. Screenshots and sys error report bellow. What have I done wrong? And what to do to fix it all? Thanks!

Did anyone already thought or experienced to just cut out a square at the back of the frame? its not elegant but my imacs back just faces the wall :) for thermal reasons i can imagine just to stick it back.
