So I'm not sure if this is a hardware or software issue so I posted it here. Basically I hadn't used the built in camera in a little while before upgrading to mountain lion so it is possible that it stopped working before that, It was working the last time I tried to use it, and I noticed it not working after the upgrade. Basically if I open a program like photobooth it says there is no camera connected. So I was wondering if anyone knows if this is a known issue of mountain lion killing the camera, or if anyone has ideas of how to fix it. Applecare is up so if it is a hardware issue there's not much I can do about it.
