I cant remember when I didnt have to, but almost everytime I update something through software update that required a reboot, I always had to reset my PRAM. Why you ask? Look at my attachment file. Thats what happens everytime I update. Now I really dont care, and this is the third time I had to reset my PRAM (but it has been 4 times since i have updated something that needed to reboot) but what is your diagnosis? I dont think I will take it to Apple right now because school starts in less than 2 weeks. But what is the most probably cause of this? Logic Board screwing up?
