I just bought a Mac Mini G4 with Leopard installed in it. I got tired of slow PCs and decided to finally upgrade to a Mac since I use them at school for up to 3 hours a day. I have installed all the programs I need for my film editing, photography, and design. But I decided to hook-up my webcam so I can video chat with friends. I am not that savvy about webcams and Mac's. It is a older Logitech QuickCam Webcam. It does not show that it is plugged into the usb port at all. If anyone could tell me what to do, besides having to buy a new one unless I absolutely have to, and get it working with iChat I would appreciate it. Thank you.
