Back in October I upgraded my year and a half old 13" MacBook Pro to Snow Leopard in anticipation of the Mac App Store and have suffered no less than five kernel panics since installing SL. Now, I've owned several Macs over the years and only experienced two kernel panics, both due to hardware faults. After each of the KPs I've had on the MacBook Pro I ran the Apple Hardware Test immediately afterwards which reported no errors. I know it sounds far-fetched but could these panics stem from Snow Leopard itself? Has anyone else with a 5,5 MacBook Pro experienced multiple panics under Snow Leopard? Thanks in advance.
