Hey guys, I have a late 2009 macbook that started having kernel panics about a month ago. It always seems that they come when I'm doing homework. I have called applecare 3 times( about to be 4) and i took it to a genius. The Genius said that it could be a hardware problem and did a diagnostic on it. Nothing came back. He recommended that i go and buy an external hard drive. So $100 later I back my stuff up. It happens again, so I call applecare and they help me reinstall lion. The kernel panics stopped. Then last night, as i am typing my paper it happens again. I don't know what to do. I am still under warranty so shouldn't apple take care of it?
