    • Three 1.8 mm screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your Mac.

    • Do not completely remove the antenna plate; it is still connected to the Mac mini by an antenna cable.

    • With the Mac mini's ports facing you, carefully lift the antenna plate and slide it about an inch to the right.

    • The antenna cable connector and socket are fragile.

    • Use the point of a spudger or fine tweezers to gently pry the antenna cable connector straight up off its socket on the logic board.

    • To reconnect the cable, use tweezers to position it carefully over its socket on the logic board, and then press it straight down until it snaps into place.

    • If you need more slack in the cable, you can temporarily pry it from the clips securing it to the antenna plate.

Wow, I have no problem doing this, but I walked my parents through a RAM upgrade on their 2014 Mac Mini when all you to do is remove the bottom cover and pull the modules out. I’ve already told them to skip this model. Great guide, I have the board in front of me and waiting for Amazon to deliver the new RAM today. Thanks!

What’s the antenna cable for? My WiFi works without connecting it

Me too.It just works without plate. Not sure whether it’s assistant antenna for further and reliable signal… or just fake parts to check whether users tried to tear down and give Apple chance to reject customer service…you know it’s quite fragile part.

Broke the female connector in the process of replacing the ram. It detached from the board. It's there a way to fix it? Wifi signal is still working but not as strong. Everything else working. Thanks
