I bought the mini 9 with os x (10.5.6) already installed. It came with 2gb ram and 8gb hd. Everything works great except for the webcam and the left click button which I have to press sometimes more than once for it to actually work. I was thinking maybe I should re-install OS X to it but was wondering if that was possible with OS X already installed. I figure I am missing a few drivers or some of them didn't go through right. Any suggestions or links would be greatly appreciated. Thanks before hand.
