Apple released two new firmware updates for the Mac Pro on Tuesday. The Apple Mac Pro SMC Firmware Update addresses fan behavior, and the Apple Mac Pro EFI Firmware 1.0 update fixes several startup issues and Boot Camp issues. Both are available via Software Update, and require Mac OS X 10.4.7.
Apple also released Apple Intel firmware restore 1.1. This utility restores the firmware in Intel-based iMacs, the Mac mini, MacBook Pro, MacBook, and Mac Pro to original factory condition if other firmware updates fail or are interrupted. The firmware restore utility is free and available for download at the Apple Web site.
