If you own a 27-inch iMac that's afflicted by the cursed screen-flickering problem, Apple's 27-inch iMac Display Firmware Update 1.0 will come as very good news. The update claims to correct the iMac's firmware to ensure proper display performance, eliminating the widespread flickering issue marring the displays of many 27-inch iMacs (see "New iMac Screens Cracking and Flickering," 10 December 2009). Be sure to follow Apple's warning not to turn your computer off during installation. More information regarding installation is also available on Apple's Web site. The update is available via Software Update or the Apple Support Downloads page. (Free, 294 KB)
