Hi Tim,
If you are looking for a camera that you can use on both your MAC and a PC, please consider one of the new UVC (USB Video Camera) standard web cams. These are produced by Logitech and Creative (...and probably others) and have the UVC logo on the box. They are Plug and play for MAC, but you have to load the included driver for PC. Regardless, you can use these cameras on either platform.
Best Regards,
