The Firmware Restoration CD can restore the firmware of an Intel-based Mac computer.
Note: Restoring your firmware will reset some of your computer's preferences to defaults.
You can only use this to restore the firmware after an interrupted or unsuccessful update. If your computer is already in this state, you'll need to download the software and create the CD on another Mac computer, or you can take your computer to an Apple Store or Apple Authorized Service Provider to restore your firmware. This CD can be created on either a PowerPC- or Intel-based Mac, but only works with Intel-based Macs.
- Only for Mac Pro (mid 2010) models.
- Refer to this Apple knowledge base article to find firmware restoration CDs for other Intel-based Macs
