Use multiple libraries in the Apple TV app on Mac
You can have more than one media library in the Apple TV app. For example, you can have a library of home videos that doesn’t appear in your regular library, or you can keep some of your videos in a library on an external storage device.
If the Apple TV app
is open, quit the app.Press and hold the Option key while you re-open the Apple TV app.
In the window that appears, do one of the following:
Create a new library: Click Create Library, then name your new library.
Tip: Avoid names like “TV” or “New TV” to help you find your library later, and make sure each library has its own unique name so you know which is which.
Choose a different library: Click Choose Library.
In each library you create, you can select different settings for the types of content that are displayed, restrictions and the library name. To configure settings for a library, choose TV > Settings after you choose that library in step 3 above.
