Home Sharing requires a computer using the latest version of iTunes,* and one or more of the following devices on the same home network:
- Another computer using the latest version of iTunes.* You can use Home Sharing with up to five computers.
- An iOS device with iOS 4.3 or later
- Apple TV (2nd generation) with Apple TV software version 4.2.1 or later
- Apple TV (3rd generation) *Additionally, you should install any available updates for your version of Windows or Mac OS X.
Home Sharing requires all computers, iOS devices, and Apple TVs (2nd generation and 3rd generation) to use the same Apple ID.To verify your intended Apple ID is enabled on all of your devices:
- On Apple TV, navigate to Settings > Computers and look in the bottom-left.
- On your iPod touch, iPhone, or iPad, navigate to Settings > Music.
- On your computer, open iTunes. Open the File menu and select Home Sharing. If the incorrect Apple ID is listed in iTunes, do the following:
A maximum of five computers can use Home Sharing at one time. If this limit has been reached and you want to add a new Home Share, deauthorize one or more computers by choosing Deauthorize Computer from the Storemenu in iTunes. For more information about authorization and deauthorization, see About iTunes Store authorization and deauthorization.
Home Sharing requires a home network with an active Internet connection. All the devices you want to use with Home Sharing need to be connected to your home network.In addition, verify that:
- All your devices are connected to the same router, if you have multiple routers. Using multiple routers may prevent discovery between these devices.
- Your devices are not using a Virtual Private Network (VPN), or that they are all on the same VPN. A VPN may isolate the device and cause connectivity disruptions.
- If you have a router set up with a guest network, make sure all devices are either connected to the guest network and devices on the guest network are allowed to communicate with each other, or switch all devices to the primary network on your router.
- If your computer is asleep or shutdown, or iTunes is closed, there's no access to the shared iTunes library. Wake up or start the computer and open iTunes to regain access to that library.
- Your router needs to be up-to-date. If you are using an AirPort or Time Capsule, read this article to find out more about firmware updates. If you are using a router from another manufacturer, contact the manufacturer to inquire about available updates.
If you have a firewall enabled in your router or computer, make sure that the firewall is not blocking communication between your computers. Home Sharing uses TCP port 3689 and UDP port 5353 to communicate with shared iTunes libraries.In addition, Apple TV and Mac computers will use port 123 to set the time automatically. Incorrect date and time on either the computer or Apple TV can cause errors for Home Sharing and connections in general.If you are unsure whether your router has a firewall or the required ports open, test additional devices or another network to help isolate the issue. If the devices tested work on another home network, it is your router or network configuration.For Mac OS X, you don't have to edit the port addresses, but make sure the firewall in Apple () menu >System Preferences > Security > Firewall are not set to:
- Block all incoming connections
- Allow only essential services
If you use another security/firewall software on your computer or router, follow this article or contact the manufacturer or check the documentation on how to open TCP ports 123 and 3689 as well as UDP ports 123 and 5353.
