Hey guys, I was wondering if the Late 2013 iMac 27inch models still have the Screen smudge "dust" issue or was this fixed? If you don't know what I'm talking about, it happens apprently when the iMac's screen heats up and leaves some dark marks that cannot be wiped off... Does anyone know if this was fixed? I just ordered one online and found this problem. If this problem still exists i need to change my orders/ cancel it. Someone please help! emergency!
