OK. I am going crazy trying to figure out why my iSight on my MacBook is not working. I have the latest Parallels Beta and I was wondering if it is intefering with the USB drivers that drive iSight. Can anyone tell me if they can launch PhotoBooth and get iSight working with Parallels Beta installed but not launched. I would appreciate it. If so, I'll have to take my MacBook in for repair. I have tried everything else - reset PMU, reset NVRAM, install 10.4.7 combo update, etc.
