Re-connecting the antenna lead plug was by far the hardest part of the entire operation for me. I found it easiest to roughly position it and then screw the guide in loosely before trying to get plug properly back into the socket. When it goes in you will feel a very slight click. You can tell it is correctly located by comparing it with the two sockets beside it. If it looks like them, then you have it in correctly.

I found I had to use quite a bit of force to seat the RAM properly.

Note carefully the tiny clips that grip each side of the RAM module; I found I had to use quite a bit of force to seat the RAM properly.

The screws are T6 “Tamperproof” requiring the T6 Torx driver with the hollowed tip, not the standard T6 Torx.

My Mac mini screws are smaller than T6 or T5!!!
