Apple introduced iTunes Home Sharing in iTunes 9 as a way for multiple computers in a single house on the same WiFi network to share music between their iTunes libraries. With it turned on, you can listen to music on another computer in your house and copy music between computers or iPhones and iPods. It's also the way that iTunes libraries connect to the second-generation Apple TV. Here's how to set it up.
- Make sure you have iTunes 9 or higher. Home Sharing was not available in earlier versions.
- There are two options for turning on Home Sharing: from the left-hand tray in iTunes (though this option will disappear after the first time you turn on Home Sharing) and from the Advanced menu. Click on either.
- In order to turn on Home Sharing, enter the iTunes account information for the account you want to share from. All devices connected via Home Sharing must use the same iTunes account.
- Click "Create Home Share." This will turn on Home Sharing and make your iTunes library available to other computer on the same WiFi network.
- Look for the "Shared" section in the left-hand tray in iTunes to find other iTunes libraries you can access.
- To turn off Home Sharing, go to the Advanced menu and click "Turn Off Home Sharing."
