Since I installed the 10.6.5 upgrade last night, my Mac Mini has crashed 4 times due to a Kernal panic. Upon restart, it won't recognize my wireless bluetooth keyboard & I have to unplug and replug my USB mouse to get it to work. Anyone have any idea why this is happening? I recently switched to this Mac because I was tired of dealing with Windows' problems, but this doesn't instill a lot of confidence in me re: Apple OS. Any help would be greatly appreciated.
