If you have a swanky new 27-inch iMac and have been experiencing problems with a flickering display, Apple has an early Christmas present for you.
Almost as soon as Apple started shipping the hot new 27-inch iMacs, the support discussion forums on Apple.com started filling up with complaints about flickering and image corruption in the displays. Rumor has it that Apple even slowed down shipments of the units to correct the problem.
But yesterday afternoon, the elves at Apple released a 683 KB patch to address the problems,
available for download from Apple’s support site (and it should pop up via Software Update for afflicted systems, too). The patch updates the firmware on the ATI Radeon HD 4670 and 4860 graphics cards that come with the 27-inch iMacs.
The new 27-inch iMac was recently benchmarked as one of the fastest Macs yet, which have made them a popular item even with power users. The desktop computer is so popular that Apple even issued an apology for the shipping delays on the higher-end models (as long as two weeks) as they scrambled to catch up.
