In keeping with past efforts, Apple has released a Firmware Restoration CD for early 2009 Mac Pro and Xserve models. The CD can be used to restore your computer's firmware in the event of an unsuccessful or interrupted update, though if that's already happened, you'll need to download the disc image and create a CD on another computer or bring your machine to an Apple Store or Apple Authorized Service Provider. The CD can be made on any Mac, but can be used only on the supported models. (Free, 22.5 MB)
