I have a Macbook 2.0Ghz. 1g of ram. (I did all the updates.) This happened a couple times with my new Macbook: I turned off the computer ( power off ). Then later i found out that the machine was still hot. The computer was OFF, not on sleep (sleep LED was NOT on), I turned it OFF. But the machine was still running, i guess the hard drive was still running/on, i should say that. I was like what the hell? Then when i press the start bottom, it won't turn on. I had to hold down the start bottom for a few seconds, to start the computer. After successfully loading OSX, it showed an error message "OSX was quit unexpectedly......". Any experts out there know what is going on here? Any suggestions? Thank you very much.
