Use Home Sharing to share media from a computer to other devices - Apple Support
To view Home Sharing Content from the Mac on Apple TV, use the Computers app on Apple TV. That will try to find a shared library on the home network that has the same Apple ID in its settings for Home Sharing. If it finds multiple computers that qualify, then you will be asked to make a choice for one at a time. If it finds none, then it will say ‘No libraries available’.
Home Sharing files will not show in the TV app on the Apple TV box. As mentioned earlier, use the Computers app instead.
Add your files to the library using iTunes or using the TV app on your Mac. By default, the shared files may be moved or copied to a standard folder, but you can override that and use the files just where they are. In both cases, it only matters that the shared files are added the the library database. There is no sharing folder as such.
The Home Sharing files will have to be compatible with Apple TV. Incompatible files would still show in the Computers app, but refuse to play.
Untagged video files will be shared as “home videos”, which is a separate tab/category in the Computers app.
Movies | TV Shows | Music | Photos | More | Search
You will find Home Videos, Podcasts, Audiobooks in the More tab.
If you change the Media Kind tag for a file (Home Video to something else), then you can change how your file will be categorized and shared.
