Kernel panic report help 10.6.8
Hey everyone,
I know this is a common issue, so I apologize if there is a more appropriate place to post this. My 2008 Macbook core 2 duo has been giving me the gray lock up screen for about a year now, and I'm not sure why. Here is the panic report from the last time it happened (today). I haven't seen a correlation to anything specific, but possibly when downloading larger files. I've switched browsers and reset them. I also replaced the two 1gig ram sticks with 2 gig's.
