Is this normal? I am installing a firmware update on my macbook and upon my restart, I'm getting a long, ugly beep and the breathing light is steady, rather than breathing.

How long has it been in this state? Did it restart? Was it on battery power when you did the update? – Stephen Jennings Feb 10 '10 at 4:20
It restarted and everything is fine at this point. It was not on battery power. My laptop is functioning fine now, it just seems unnatural and is possibly an indication of something else? – Chris Feb 10 '10 at 4:43

When the firmware is being updated on Apple's portable products, the long steady light and loud (rather annoying) beep is the computer indicating that its base firmware has been successfully updated. Soon after, the gray screen with the Apple logo & firmware progress bar should've appeared. Firmware updates are always a mystery though; the duration of the beep and time to overwrite the firmware differs between models, and even between computers of the same model. If your computer's working fine now like you say it is, then I wouldn't worry about it. It's not an indication of any problem whatsoever.
