I just bought a new Macbook 15" a few months ago and haven't really had any problems with it until now. I'm not new to computers in general, but this is really the first experience I've had with a Mac so I'm still trying to figure out how everything works on it. Anyway, yesterday I had 4 different programs lock up completely for no apparent reason throughout the day. First was the SystemUIServer, then Opera, Finder, and finally the Activity Monitor. 2 days ago I downloaded and installed the "MacBook Pro EFI Firmware Update 1.9" and it seemed to go fine but it keeps showing up in the software update. I tried it a few more times but it still shows up. Could the update be causing any problems with the system? And when things freeze up I know I can use the report option, but how do I go about finding out what's actually happening with the system?
