Firmware update for late AT...

Apple today posted the iMac ATI Radeon HD Graphics Firmware Update 1.0.1 for iMac owners with either the Radeon HD 2400 XT or HD 2600 Pro graphics cards. The update simply states that it addresses system stability issues in those systems, but does not mention whether any performance enhancing aspects are also included. Firmware updates require an uninterrupted patch process, so users are encouraged to follow the instructions included with the update.

The update requires Mac OS X 10.5.2 Leopard, and is available through Software Update, under the Apple menu.
