Hello! My name is ***** ***** I'll be answering your inquiry today!
I took a look at the issue that you are having and it is a pretty straightforward issue to troubleshoot.
1.) Try various applications on the Mac to make sure that it is NOT application specific.
2.) Try another user to see if the issue is user-specific.
3.) Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the camera is detected.
You could also try a command line fix and see if that works.
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
Enter the administrator password ***** requested, this is required to execute a command with superuser privileges as prefixed by sudo
Relaunch the app that was attempting to use the camera.
Let me know if this works! If it doesn't reply back and we will try something else.
If it does, please rate my answer so that I may receive credit!
Thank you for using Just Answer!
