Firmware Update Addresses 27-inch IMac Flickering

Apple has released a new graphics firmware update that corrects video-flickering and image corruption problems with the latest 27-inch iMacs.

The 683KB patch, available for download from Apple's support site, addresses reports that have surfaced on several Internet news outlets and discussion boards, including Apple's own forums, over the past few weeks. The download updates the firmware on ATI Radeon HD 4670 and 4850 graphics that come with the 27-inch iMacs.

The high performance, increased screen size and competitive pricing of the latest iMacs have resulted in extremely positive reviews and a surge in popularity of Apple's consumer desktop products. All this enthusiasm, however, has been somewhat dampened by numerous reports of units reaching customers with cracked screens, leading to shipping delays as Apple, presumably, attempts to address these issues. Earlier in December, the company publicly apologized for the unusually long delivery times, which, for the higher-end models, can be as long as two weeks.
