I got the new late 2012 iMac 21.5 inch in February and just realised there are some weird wave lines behind the glass where the camera is. i can't seem to wipe it off because its on the inside and it is ruining the light control of the camera.
Should i return it to apple and has anyone ever had this before? do i have to backup everything on my computer?
iMac, OS X Mountain Lion (10.8.4)
