Following up on reports of graphical errors with its best-selling 27″ iMac model, Apple recently released a firmware update to help resolve the issue. The update, a 683 kilobyte download, updates the graphics firmware on ATI Radeon HD 4670 and 4850 graphics cards to address issues that may cause image corruption or display flickering.

The update requires Mac OS X 10.5 or later to install and run.

If you’ve tried the firmware update and noticed any changes, please let us know.

    Received my quad iMac about two weeks ago. Flickering of the screen was apparent within 24 hours. Software update did not help the situation; in fact, the flickering became worse.

    The help rep was very kind and attentive. Sending machine back for a replacement. Another thing I noticed is how hot the screen gets.
