I just got a refurbished MacBook Pro from Apple about a week ago. A couple of days ago it started to have kernel panics. It had one, I thought, no big deal, it just happened. Then it kept happening, so I re-installed Leopard, and when I went to re-install it the first time it had a kernel panic at the beginning of the installation process. Eventually, on the second try, I got it to re-install. Since then, it hasn't had as many, but it's still having them from time to time. This is pretty annoying, because I'll just using Safari and it'll happen. Is this fixable? Is it a firmware issue? What do I do?
