hi i have a macbook pro 13 late 2009. there is something really weird about this problem. my keyboard doesn't work only a couple of keys like eject volume shift ... and the track pad when i click it always registers a secondary click this is when I'm running mac osx lion. so today i tried installing abuntu on my computer and my keyboard and trackpad work fine on linux .. what can it be?? how come it won't work on mac osx ? / ? i would appreciate if any one can help me out with this problem. thanks .
