Make a FaceTime video call using Messages on Mac
In Messages, you can start a FaceTime video call to one or more people who have a Mac, iOS device, or iPadOS device that meets these requirements.
Note: You need to sign in to FaceTime using your Apple ID and make sure FaceTime is turned on.
In the Messages app on your Mac, do one of the following to choose who you want to start the video call with:
Click the Video button in the top-right corner of the window.
Choose FaceTime Video to immediately start the call.
When someone who doesn’t have a camera answers a video call, they’re represented by a monogram and a sound level meter instead of video.
In macOS Monterey, you can use SharePlay while on a FaceTime call. See Use SharePlay to watch and listen together in FaceTime and Use SharePlay to share screens in FaceTime on Mac.
