Mac BSoD

Some people who are upgrading to Leopard are getting a "blue screen" - Which is actually just the background for the "Starting Mac OS X..." window. This blank blue screen appears for a while because Leopard basically runs the equivalent of fsck - however it just seems to crash on certain computers.

BSOD on a mac?! WTF?!?!?

That is NOT a BSOD. You don't get 'em on macs (unless running windoze). It's apple's equivalent of a bsod, except much less ugly. And much rarer.
