Well, this completely crashed my MacBook Pro. Although to be fair, I think it has to do with the fairly unreliable graphics card/drivers than anything else.
I've had no end of problems with the graphics card and graphics card drivers on this model-- both times I've brought it in to be serviced the Apple techs have simply nodded and had the machine sent in for a new logic board without even testing. I guess NVida produced a terrible batch of GPU's that Apple used on these models.
