Recently my Photo Booth on my Mac has not been working for me. Everytime I try to open the application it comes up with - ''Photo Booth cannot open because the camera is in use by another application. Close the application using the camera and then try opening Photo Booth again.''
I've tried everything, by closing all programmes open and then opening Photo Booth, restarting the computer, but nothing seems to be working. I'm not sure whether there's a problem with the application or the built in camera. Any help would be appreciated.
Thanks.
