I bought a Macbook Pro computer on Sept 3rd from MacMall. As I was using it to learn Snow Leopard (this is my first Mac, I am a long time Windows developer), it would crash every one or two hours. After calling Apple support, I dropped it off at the Apple store for diagnostic testing and repair. WhenI picked up the computer from Apple, they told me that it did not crash while they had it. They suspected a software problem, so they had done a fresh install of Snow Leopard for me. At home I went through the start up procedure with the newly installed Snow Leopard. Then I downloaded the iPhone SDK, and the computer crashed again while I was away waiting for the download to finish. I was using a USB mouse, which was the only device attached. No other software installed. I was presented with a dump that mentions terms like "panic", Kernel trap", and "page fault". Does anyone have any idea what this problem might be? I really can not use this MacBook under these circumstances.
