Any one privy with a Mac??? Recently, for no reasons and when watching vids on youtube and when editing images I get this 'Kernal panic' and the Mac wont let me do anything other than switch it off. Obviously, I lose anything im working on and have to reboot again. Here is what Mac say http://support.apple.com/kb/HT1392 Ive tried to follow what they suggest about figuring out what might be causing it. I checked and updated all my Mac bits and it seemed ok. But this morning on youtube it crashed again. Any ideas what I should do? Should I find some virus software to scan on the Mac? Dan says you dont need any? What the hell do I do to stop it happening. The only possible reasons I can think of is a virus, but then im a new mac user. Other possible reasons is I dragged and dropped a file in In Design but it didnt load up, It did nothing, so I dragged ad dropped into PS. Any help would be appreciated. Cheers.
