Any help would be greatly appreciated, thank you! Neither application nor the operating system has a way of setting a default webcam that I can find. I can manually select the webcam when I use FaceTime or Skype, but I have to manually go into the preferences for each application every single time I open it. With video though, there is no such option I can find. For audio, I can go to System Preferences -> Sound -> Input and select a device for sound input.
I have an external webcam that I would like to use instead of the webcam built in to the iMac.
