Hello all,
After my iMac 27" (latest generation, 2012) went to sleep, I put it back with the touch of a button. What was revealed was white grainy graphics covering parts of the screen (see screenshot). When I restarted my machine, there are still icon thumbnails not showing - but the grainy graphics are gone.
I did a software update of my OS X and then everything was working, seemingly.
I went away and the computer went to sleep again, and when I resumed it the issues reappeared. I restarted it and the icon thumbnails are not showing but the white color grain is gone. But the icon problem is still there after I resume my computer from sleep - icons not showing in the upper right, Safari and Finder ...
Is this an hardware failure or is there something I could do with the software to fix it?
I have tried Disk Repair and just about everything in OnyX.
