We have iMacs that we use as industrial control computers, and we connect FireWire cameras into them via Thunderbolt adapters. On previous OS X versions, we would have to go into the preferences for iChat / Messages and prevent them from automatically launching when these cameras were connected, to make sure those applications didn't mess with our own video software.
However, on Mavericks these preferences have disappeared, apparently because now FaceTime is the application that automatically launches when an external FireWire camera is plugged in.
FaceTime seems to lack any formal exposed preferences, so is there another way to disable the automatic launching of this application on the connection of an external camera (a preference setting written at the terminal, etc.)? If so, how would we do this?
