Camera Not Detected on Mac

This is what worked for me. Essentially killing the VDCAssistant process and letting it automatically restart itself. I didn’t even have to restart my video chat app I was using to see make the video work!

mac-pro$ ps aux | grep VDCAssistant
root            71691   1.4  0.3  2568156  24452   ??  Ss    2:33PM   0:00.51 /System/Library/Frameworks/CoreMediaIO.framework/Resources/VDC.plugin/Contents/Resources/VDCAssistant
mac-pro$ sudo kill {{pid listed in grep command.. in this case it's 71691}}
