If you are looking for a web cam for mac, I would suggest this web cam that I bought already for me. My mac is 10.4.11 and has been very difficult to find a good web cam, but not very expensive. The web cam is: Laser Smart Easycam 5.0 megapixel, and driver free for mac and mac compatible. You can buy it on ebay or in some shop. Also you can have a look on www.laserco.net. This webcam works very well.
