As others have said, open Terminal and enter >

Then hit return. Shuts down what ever faulty process was happening, then when you click an app that uses the camera, the camera should be detected again.


Worked for me with a Mac Mini 4 and the FaceTime HD Camera in a Thunderbolt Display.

Hallo Grant Bennet-Alder,


yes, the Thunderbolt Display was unplugged from electricity overnight. I have just turned on the macbook with the Thunderbolt Display connected. Only Thunderbolt Display is on because the lid of the macbook is closed. Camera of Thunderbolt Display does not work (as long as I have not disconnected and reconnected the Thunderbolt cable).
