I am typing this from my Mac Mini since my 2009 Mac Pro (6 months old) no longer boots. I did the new Mac Pro firmware update yesterday and everything seemed OK, didn't think about it too much. However, today the computer froze when I launched Firefox, couldn't make Force Quit work, and finally hard-powered down the computer. Booting it up again, it goes back to the grey "firmware update" screen, with the bar on the bottom of the screen. Except it gets stuck about 1/4th of the way and never completes. I think this is a firmware update issue since it looks just like the firmware updater, and I just did the update. Anyone else have any ideas? I already removed all unnecessary components, etc. Thanks.
