Introduction

Prerequisite-only guide to remove the lower support bracket in an iMac 27" 2017.

    • Use a Phillips screwdriver to remove the nine 3.2 mm screws securing the support bracket.

    • You may need to peel up the display adhesive lining the bottom edge of the iMac enclosure to access the screws.

    These are new steps from when I did this on my late 2015 retina iMac so I believe step 25 and 26 are optional (you can cope without doing it).

    I did not find it necessary to remove these screws and this bar

    I lost these 8 during the reassemble. The manual tells I need eight 3.2mm screws.

    Can anyone help to clarify what screws I need. I don't really understand this size. Is this M2x3mm?

    • Remove the lower support bracket (a.k.a. "chin strap") from the iMac enclosure.

    It's quite possibly the most difficult part to put back in the entire process

    The screws are tiny and the there is no easy way to line up the holes on the bracket with the screws

    Having got this far - it wasn't even all that necessary to remove this part in the first place

    Severe pain in the neck

    After an hour of painstaking mess - I managed to get 7 out of the 9 back in

    By that time I could care less about the remaining 2

    With the right tools and technique, the bracket can easily be replaced in under a couple of minutes.

    Use a screwdriver with a magnetized tip which frees up one hand and place a screw on the tip first.

    Then line up the screw hole on just one end of the bracket and using a pair of tweezers from the side, hold the bracket in place while you put in the screw.

    Next, do the same on the other end of the bracket. After that, all of the screws in the middle are quick to replace. I didn't really have to touch the bracket again after the end screws were in place.

    Hope that helps someone else since removing this bracket does make later steps a bit easier.

    I used Max Z tweezers technique but screwed one screw in at the end and then worked my way to the other end.
