Hey guys, This is something that I've been trying to fix for the last 4 or so hours and it's driving me insane. The trackpad for my white macbook has stopped working entirely, it's not scrolling, not clicking.. nothing.. When I plug in an external mouse it works, and the keyboard works, everything else seems absolutely fine. I don't know what to do, I've already booked at a genius bar but that's in a couple of days - do any of you have any ideas? Thanks so much. Candice.
