It’s rather common for all members of a household to want to share their music or movies with each other. Here’s how you can do this easily with iTunes!
Go to iTunes > Preferences > Sharing and check the box labeled “Share my library on my local network.” If you want to limit who can access your library, set a password in the box near the bottom. Otherwise, everyone will be able to access it. You can limit sharing to the content or playlists of your choice in your iTunes library.
Once Home Sharing is turned on, other iTunes users can see your library by clicking the Library drop-down menu in the top-left of iTunes. iOS device users can also access libraries through Home Sharing by going to the “More” tab in the Music or Videos apps. And don’t forget to back-up all the content in your iTunes library!
