Dan (number 2) brought word of several EFI Firmware updates yesterday. I took the plunge and applied the Mac Pro variant to my own lovely machine. The good news is that although I’m typing this on my Powerbook, my desktop is just fine. This update acted like the rest of them. Am I the only noticing that the Intel Macs get far more firmware updates than the PowerPC machines ever did? I’m not complaining, but it’s interesting.
First, the update gives you the set of instructions. It shuts down the Mac. You press and hold the power button until the light flashes or you hear a long beep. Release. Then wait as the progress bar slides across the screen. This is where things got interesting. My Mac Pro suddenly kicked both optical trays open. Once the update was finished, the trays closed on their own. Like the title says, all I could think of was the game Hungry, Hungry Hippos.
At this point, I had another little mishap (completely benign). My Mac Pro started into Windows for some inexplicable reason. Choosing my Mac OS X boot drive in the Boot Camp panel and restarting set things right. Hopefully it was just a one time thing.

I'm fairly certain that this Mac Pro firmware update added a "Processor" preference pane into my System Preferences. I don't ever remember seeing that there, but then again, maybe I'm insane.
