Watch together using SharePlay in the Apple TV app on Mac
With SharePlay, you can watch movies or shows with anyone, anywhere. You can start a FaceTime call on your Mac, then start watching a movie or show in the Apple TV app. The video plays in sync for everyone on the call. Everyone can control playback from their devices — so you and your friends can laugh, cry, scream or sigh at the same time.
Note: Some movies and shows require a subscription or purchase. If you watch a purchased movie or TV show, all SharePlay participants must also have purchased or subscribed to the item in order to watch together. FaceTime, or some FaceTime features, and other Apple services may not be available in all countries or regions.
