I downloaded a BT firmware updater from apple's software update. I'm running it on my 12" rev. B PB. It says it can take up to 15 minutes. But right now it's been 20 minutes and it still says "preparing to update device" (the screen hasn't changed). This happened when I tried to run the bluetooth firmware off of the CD that came with my Apple BT keyboard, too. what is going on here? The firmware updater app just has the perpetual spinning color wheel. It says I can't quit, but I sorta have no choice. It's not making progress. Why does this keep happening? do I even need this update? please help ASAP!
