Logitech C910 webcam El Capitan compatability?

Solution 1:

Fortunately, there is another trick that seems to fix the problem immediately using a command line force quit, and does not require a reboot:

• Quit all open apps that may try to use the camera

• Open Terminal, found in the /Applications/Utilities directory in OS X

• Enter the following command strings exactly, then hit return:

    sudo killall VDCAssistant
  

• Still at the terminal, issue the following command as well:

    sudo killall AppleCameraAssistant
  

• Relaunch the app that was attempting to use the camera

Solution 2:

I had the same issue with a C920, it kinda works but doesn't quite 'fit' into the OS. Logitech didn't seem to offer any support for it at all.

I got round it using an intermediary app called Webcam Settings [$7.99/£5.99] which essentially turned it into a useful camera again.
