Click Home in the sidebar, then click a movie, TV show, or event you want to watch.
The options you see depend on what kind of content you’re viewing and whether or not it’s available for you to watch.
Note: When you click an item in the Continue Watching row, it begins playing immediately (unless you haven’t yet rented it, purchased it, or subscribed to its channel).
Do any of the following:
Play the item: Click Play. (The Play button is available for free content, content you’ve already purchased or rented, or content on Apple TV channels you subscribe to.)
Subscribe to Apple TV+ or an Apple TV channel: Click the subscription button, then follow the onscreen instructions.
Buy or rent a movie or TV show: Click Buy or Rent, then select the option you want and confirm your purchase or rental. For details, see Change Media & Purchases settings for your Apple Account on Mac
