Facetime camera not working
My Facetime app isn't working. Whenever I open it I get this image. I have already tried to reboot, and to disable and enable facetime. Also, the problem only occurs on this app, Photo Booth and Skype work great, here instead the camera is not turning on, the green LED next to it remains off.
