Ok. Well here's the thing. That's not altogether true.
The computer doesn't recognize it without the Macam driver.
And even then, It opens in the Macam program but not in IChat or IMovie.
Then when I downloaded a patch called IChatUSBCam, it works sometimes in IChat with certain people & not with others. It NEVER works with IMovie. Without downloading these programs I get nothing.
The IChat USBCam is a free 7 day trial. The entire program is $10. to buy. But if it only works with some people, I'm better off just buying a new Webcam that ALWAYS works in IChat & IMovie.
