Mac: Camera not available
Note:
This post was written in 2014 and discusses technology that may be outdated.
The concepts may still be relevant, but specific tools/versions have changed.
My Macbook Pro sometimes doesn’t detect it’s web camera when I’m trying to join a video call and it’s painful to have to reboot the machine to fix it. A simpler way (especially if you have root access to your machine) is to kill VDCAssistant from the command line.
sudo killall VDCAssistantOnce you’re done, restart the application that was attempting to use your web camera :)
