Facetime not working in clamshell mode with external webcam connected
Does anyone know how to get facetime to work with my mac in clamshell mode? I have a usb webcam connected as well along with the monitor. I can open face time and it will show the camera feed but when i try to call someone it doesn't work and it ends the call. Same thing when i try to transfer from my iPhone to my mac it ends the call. any information would be appreciated.
