So received imac back from Apple and the screw on the bottom where the memory goes into has bee stripped. I managed to take the plastic cover off and took it back to Apple and they told me they wouldn't replace the stripped screw (even though they ruined it). Just curious to know if anyone knows the screw thread size? I don't believe a hardware store would have it, since it is meant to fit perfectly into that mac. Or perhaps know of a website where they would sell this screw? This is for the newer imac!
