I'm posting on my brother's account. He suggested i ask for help here. I accidentally somehow disabled my iSight built in camera on my MacBook. I don't really know how i did it, but it i think it happened when a was messaging a friend on her messenger (AIM) and she invited me to a video chat (this is my best guess anyway). Also, what really bothers me is that when i look at my hardware under "about this mac-->more info" it no longer lists built in camera under the USB section. Can anyone give me any tips on how to fix this? Thank you.
