In an attempt to fix on-going system freezes, Apple on Thursday released its iMac Graphics Firmware Update 1.0 for 20-inch and 24-inch aluminum iMac computers with the ATI Radeon HD 2600 Pro graphics. The company said the update -- which updates the graphics firmware on the ATI Radeon HD 2600 Pro to improve system stability -- is designed for systems running Mac OS X 10.4.10 with iMac Software Update 1.2.1 or Leopard with iMac Software Update 1.3. Specifically, it updates the graphics firmware on the ATI Radeon HD 2600 PRO card to address issues that may have caused the computer to freeze, Apple said. However, the company noted that not every 20-inch and 24-inch aluminum iMac computer requires this update, saying that the update will automatically present itself if required (after applying the previous Tiger and Leopard updates).
