Apple introduced iTunes Home Sharing in iTunes 9 as a way for multiple computers in a single house on the same Wi-Fi 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. Learn how to upgrade iTunes, if necessary.
- Click on the File menu, choose Home Sharing, and then click Turn On Home Sharing.
- In order to turn on Home Sharing, log in using the Apple ID (aka iTunes account) information for the account you want to share from. All devices connected via Home Sharing must use the same iTunes account.
- Click Turn On Home Sharing. This will turn on Home Sharing and make your iTunes library available to other computer on the same Wi-Fi network.
- In iTunes 11 and higher, click on the View menu and then choose Show Sidebar (in earlier versions of iTunes, the sidebar is shown at all times). 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 File menu, select Home Sharing, and click Turn Off Home Sharing.
