Help - Macbook Pro won't start after running update
Today I installed the big batch of updates Apple released recently (I think it was on July 31) on my 2.4 GHz Macbook Pro. When I turned it on, I was told there was one last update that required me to turn off the machine and then hold down the power button.
I did, and the machine started to come on, but I guess I held the button down a little too long. Now the machine won't turn on. Everytime I press the button, I hear the same sound I always get when I turn on my machine, except that now the sound just goes on and on and on, and the MBP never actually boots up.
I wish I could remember the exact name of the update. I think it might be the EFI Firmware Update 1.2 that's described at http://www.apple.com/support/downloads/macbookproefifirmwareupdate12.html. That scares me because the words "Important: Do not interrupt the update" suggest things can go badly if the update doesn't go right the first time.
Any advice as to what I should do?
Macbook Pro 15/2.4/2GB/160GB, Mac OS X (10.3.8)
