iTunes Home Sharing allows you to share iTunes media libraries between home computers (no more than 5), and through Wi-Fi network play content on iOS devices (iPhone, iPod, iPad), Apple TV.
iTunes Home Sharing is a great feature, and any user can make the most of it. However it is doubly frustrating when it won’t work. Below we explain how to solve a handful of the problems that crop up most frequently with Home Sharing:

Troubleshoot Problems with iTunes Home Sharing on Windows and the Mac
Home Sharing Isn’t Available in iTunes 8 or Earlier
Apple introduced Home Sharing in iTunes 9, so if you have an earlier version of iTunes, you need to upgrade and get the latest version of iTunes. The only exception is if your computer’s operating system doesn’t support the latest version if iTunes, In this case, get the latest version your current OS can handle.
Home Sharing Computers Can’t See Each Other on the Network
If your iTunes Home Sharing computers can’t see each other’s songs and other items on the network, first at all make sure that the computers are connected to the same network. In a home setup, this is usually clear enough, unless you have deliberately divided the network into different subnets (logical sections) to keep your loved ones away from your mission-critical files. But if you are dealing with a bigger network, such as a dorm network, it may be divided into different subnets, in which computers on each subnet can see only other computers on that subnet.
Second, make sure that iTunes on each computer is set to use the same Apple ID. If you have set up two or more Apple Ids, and you are using different ones for different computers, you will need to standardize on a single Apple ID for Home Sharing.
If the computers are on the same network and using the same Apple ID, check whether the computers can see other shared items – for example, printers and shared folders or files. If they can, most likely the router is set to suppress multicasting, a feature that sends data packets to several computers at once across the network. Home Sharing requires multicasting to be turned on, but some routers turn it off by default to help avoid too much traffic bouncing around the network and overwhelming it.
If this seems to be the case, log in to your router’s configuration utility or web-based configuration screens and look for an option for turning on multicasting. Routers use different terms for this, and the configuration tools hide it in different locations, so you will need to use your initiative. For example, some Linsys routers have a Filter Multicast check box, which you can find in the Security – Firewall area.
Dealing with Occasional Glitches in iTunes Home Sharing
Once you have gotten Home Sharing working, it usually works consistently. But if you find Home Sharing is acting hinky, try these four basic moves to get it working again. Start at the beginning and stop when the problem disappears:
- Restart iTunes: Begin by restarting iTunes on each of the computers you are using.
- Restart your wireless network connections: If your computers are using wireless network connections, drop each connection. Then reestablish the connection. For example, on Mac OS X, click the Wi-Fi menu or AirPort menu on the menu bar. Then click Turn Wi-Fi Off or Turn AirPort Off. Click the menu again, then click Turn Wi-Fi On or Turn AirPort On.
- Restart your PC or Mac. This move is tedious, but it clears up many problems.
- Restart your router. Doing this is even more tedious, because it takes down your Internet connection, but it often solves problems with Home Sharing.
The Home Sharing Item Disappears from the Source List When You Set Up Home Sharing
This is not actually a problem. In fact, it is just the way the iTunes user interface works, and it is a bit confusing.
Before you set up Home Sharing on a computer, the Home Sharing item appears in the Source list in iTunes. This item gives you access to the controls for setting up this feature. But as soon as you finish setting up this feature on that computer, the Home Sharing item disappears from the Source list. Instead, you see whichever Home Sharing libraries are available, each showing a house icon to indicate that it is Home Sharing rather than plain old sharing. This is normal.
iTunes Home Sharing Transfers Duplicate Files
When transferring files, Home Sharing doesn’t check if your library already contains copies of the files you are transferring. So if the files you tell this feature to transfer include files your library already contains, you will get duplicate files.
To avoid this problem open the Show drop-down list and choose Items Not In My Library rather than All Items. iTunes then displays only those items in the shared library that your library doesn’t contain.
Tip: You can use the File – Display Duplicates command to identify duplicate files within your library.
Home Sharing Doesn’t Transfer Playlists and Ratings.
Some people expect Home Sharing to transfer playlists and ratings from one computer to another. But this is simply something it doesn’t do.
If you want to copy or move your playlists and ratings from one computer to another, you need to export your library from the source computer (that is, the computer that currently contains it) and then import it to the destination computer. Before you import the library on the destination computer, use Home Sharing to make sure that the destination computer’s library contains all the files that the source computer’s library contains.
