mac 10.6.3 won't restart after software update
I just installed Snow Leopard on my mac and that was successful. I went to do a software update afterwards (hoping to move up to 10.6.8) and it went through, but when the computer had to restart, it would just shut down, and reboot to the purple-ey space-ey background image....and just stay there.. The computer will shut down fine by holding the power button, and it will start up fine. It's just after the software update, that it will not restart fully. Any ideas?
MacBook Pro, Mac OS X (10.6.3)
