Use DVD Player to watch DVD movies on Mac

If your Mac has a built-in DVD drive or is using an Apple USB SuperDrive, just insert your DVD into the drive. DVD Player opens automatically.

To control playback or access the DVD menus, use the onscreen controls. Other features, such as subtitles, closed captioning, and parental controls, are available from the menu bar. You can use the Space bar and other keyboard shortcuts and gestures as well.

If you have DVD media stored on your Mac:

1. Use Spotlight to find and open DVD Player.
2. From the DVD Player menu bar, choose File > Open DVD Media. 
3. Select the VIDEO_TS folder that contains the video you want to play, then click Open.

• Content-protection requirements prohibit DVD Player from displaying content when you're using screen-sharing software, mirroring the screen using AirPlay, taking a screenshot, or recording the screen. DVD Player displays a gray Viewer window instead.
