Photo Booth can't find camera
This is getting frustrating. I get a message at least once every time I try to open up Photo Booth. (see attachment). This is a new computer (iMac 5K) and this never happened to my 2006 iMac. I don't get it. It can't connect to camera. Only way I find it works again is if I turn the computer back on. This is ridiculous. I only have Safari opened and nothing. Anyone know what the problem is? I've found so many inconsistencies with El Capitan it's been really an annoying experience.
iMac with Retina 5K display, OS X El Capitan (10.11.6)
