MacBook Pro EFI Firmware Update 1.3 Released

by Jeff Carlson

Apple has released MacBook Pro EFI Firmware Update 1.3 [1], which "fixes a display issue on 2.2/2.4 GHz 15-inch MacBook Pro models," according to the minimal text on Apple's download page. MacFixIt [2] speculates that this update fixes a color distortion problem introduced in the earlier MacBook Pro Software Update 1.0 [3], which is required prior to applying the latest firmware update.

Apple also released Firmware Restoration CD 1.3 [4]. This utility (a 22.5 MB download) burns a CD that can be used to start up and repair an Intel-based Mac that won't work due to an interrupted or failed firmware update. The CD won't restore a machine's firmware if a firmware update was successfully applied. Needless to say, download the utility and burn a CD before applying the MacBook Pro EFI Firmware Update.
