Pause a FaceTime video call on Mac
You can pause a FaceTime video call to temporarily stop transmitting video. Both participants can still hear each other talk unless you mute the call.
On your Mac, do any of the following:
Pause a video call: In the FaceTime app , click the yellow minimize button at the top of the FaceTime window or switch to another app.
If you’re in full-screen view, first exit out of the view.
If you’re on a Group FaceTime call, the minimize button only minimizes the screen; it doesn’t pause the call.
Resume a paused video call: Click the FaceTime icon in the Dock.
