  • These screws are captive in the iMac. The center screw will stop turning after about 3.5 turns and the outer screws will stop turning after about 5.5 turns. Do not try to remove these screws from your iMac.

Some models (with light sensor) have only the two outboard screws.

I broke mine trying to disconnect it. It was very fragile. Better to just skip disconnecting it. Leave it connected to the hard drive bracket, and unscrew the bracket from the hard drive. Then screw the bracket to the new hard drive.

Perfect! I didn't disconnect it and the cable had plenty of slack! Great job!
