How do I view a webcam image on OS X 10.11. I have a webcam previously used on Windows and just want to use it as a camera.
If you just want to see what your webcam is showing:
Open QuickTime Player --> File --> New Movie Recording
It will give the option to record what your webcam is seeing but you don't have to. It will show a video feed from your webcam.
As an alternative to QuickTime Player you can use VLC. You'll have to download it from VLC's website.
Open VLC --> File --> Open Capture Device --> Tick Video --> Choose your camera for the drop down list --> Click Open
