I just bought a new Logitech webcam for my iMac. I've realized that it's not compatible and may never work. It's the first time I've ever hooked up a piece of hardware to my Mac and it hasn't recognized it. Does anyone know if there are any good third party drivers that will work with the webcam? Thought I saw one for sale a while back that would give you the option to switch between the built in cam and an external cam. Thanks!
