I followed the advice on this forum and successfully installed a Crucial M4 SSD in a mid 2010 Mac Mini. I couldn't replace the antenna screen properly, though. It sits directly above (or below) the SSD. The holes for the screws of the screen refused to line up, as if the SSD is too thick to allow the screen to sit properly. I believe that the screws on the side of the SSD are sitting in the grommets, but I could be wrong. Has anyone else with an M4 encountered this problem? Thanks!
