Apple firmware update aims to fix iMac flickering
Apple issued a firmware update today for all 27-in. iMacs that is designed to fix display problems, including flickering screens, that have been reported by hundreds of recent buyers.
"The 27-inch iMac Graphics Firmware Update applies to the graphics firmware on ATI Radeon HD 4670 and 4850 graphics cards to address issues that may cause image corruption or the display to flicker," Apple said in the typically-terse description of the hotfix.
Display issues have plagued Apple's 27-in. iMac desktop computers since the new machines were Oct. 20. Users have reported cracked screens, a yellow tint in part of the display, and irritating flickers that come and go. The problems prompted one Canadian Web developer to collate the complaints on a specially-built Web site, and may have been one of the reasons why Apple slapped a two-week shipping delay on 27-in. iMacs earlier this month.
