Hi, I have a Macbook pro Late 2007 with a built-in iSight (of course) and Mac OS X 10.6. Some weeks ago my iSight started to be not recognized by software like Photo Booth of Skype. As I don't use it frequently I didn't search a solution but now I miss my webcam. Photo Booth simply show a message like "webcam not connected". I think that the problem started when i uninstalled an app which emulate a webcam from a video file. But I can't remember the name of this app. What can I do now? Thanks.
