When I power on I get a screen with just the Apple symbol in the middle. It doesn't respond to any keypresses, and when I press CapsLock and/or NumLock those lights on the keyboard don't light. On one powerOn instance I did see a progress bar slowly filling in under the Apple symbol. I took that to be an OS update taking place, but I didn't stay with it to see what happened when it finished.
Is there something like SafeMode in the Mac world? Hopefully with some repair options?
