...  Now - if they'd only release one of these 'Firmware Resets' for the entire Intel range (not just the Mac Pros) ... it would make reseting botched Firmware/BootCamp/Software Updates sooo much easier than carting your Intel Mac into the 'Geniuses' at the Apple Service Centre ... !!!! ... ps - is it just me - or does everything Apple & Mac & Intel feel like one big giant BETA !! ?   (Version 1.5)

GREENIE  It would be handy for those who do know, and if you call up Apple Support they could tell you about it and if you have a 2nd computer or a friend who owns a computer to download and burn it. Also for the service tech that you take the computer to could use this.   (Version 1.2)

TIM27  The bad thing is, most people will not even know this exists before they do their firmware update. So really, what's the point?  (Version 1.2)
