I just purchased a new 27 iMac and I have noticed the glass panel is slightly mis-aligned. I know the panel is held on by magnets, but is it possible to shift it from side to side ? ( less than mm should do it ). I have no experience with this issue and before I put a suction cup to it, want to know if anyone else has had this issue. I don't want to lug the computer back to the Apple store if it is a simple adjustment.
