Follow the steps in this guide to upgrade or replace the SATA hard drive in a 21.5" Retina 4K 2017 iMac. Note that if you are upgrading your drive, you will need to clone your existing hard drive onto the replacement prior to performing this upgrade to keep your files and operating system.

Some images in this guide use a 2015 iMac, which has minor visual differences. These differences do not affect the repair procedure.

    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs are fast and easy with an iMac service wedge, but can be completed without one.

    • 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.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

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

  2. 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.

What type of SATA SSDs are compatible with iMac? I don't want to buy the kit because I have the necessary tools, but I'd like to know which brand of SSDs work the best.

>Will take any SATA SSD.

>On a mac with a fusion drive, it just removes the spinning drive from the mix, leaving you with a separate 28gig or 128 gig SSD drive that will appear on your desktop along with the newly installed SATA SSD.

>NO TEMPERATURE monitor is needed. This generation of iMacs has done away with the propietary temp sensor. It just relies on S.M.A.R.T. tech now.

Does the screen stick back on with the same adhesive or do you have to reapply new adhesive? If yes, does it come in the kit?

Rick Hahn - 답글

You have to apply new adhesive. Go slow and careful, it’s really not hard at all.

robert Seith -

Will this work similarly for an iMac with a fusion drive? -> (what about upgrading the ssd portion?) Will there be a guide for that in the future?
