What Authorizing Your Computer Means

Authorizing a computer for Apple TV means telling Apple that this particular machine is allowed to stream content from your iTunes library to your Apple TV device. When you authorize, you're linking the computer to your Apple ID and giving it permission to access your purchased movies, TV shows, and music. Without authorization, your Apple TV won't be able to see or play files stored on that computer.

You can authorize up to five computers per Apple ID account. This limit exists to prevent unauthorized sharing of purchased content across too many devices. If you need to use a sixth computer, you'll have to deauthorize one of the existing five first.

Key Takeaways

  • Authorization happens in iTunes on your computer and links your Apple ID to that specific machine so Apple TV can access your library.
  • You need to know your Apple ID and password before you start, and your computer must be connected to the same Wi-Fi network as your Apple TV.
  • The authorization process takes less than a minute and is a one-time setup for each computer.
  • You can authorize up to five computers per Apple ID, and you can check how many are currently authorized in your account settings.

Steps to Authorize on Windows or Mac

Open iTunes on the computer you want to authorize. If you don't have iTunes installed, read it from Apple's website first. Make sure you're signed out of any Apple ID accounts in iTunes before you begin.

Click the Account menu at the top of the iTunes window. On Windows, this is in the menu bar; on Mac, it's in the top menu. Select Sign In and enter your Apple ID and password. This is the same Apple ID you use for your Apple TV account. If you don't have an Apple ID yet, you'll need to create one before proceeding.

Once you're signed in, go back to the Account menu and look for an option called Authorize This Computer (the exact wording may vary slightly depending on your iTunes version). Click it. A dialog box will appear asking you to confirm your Apple ID and password again. Enter them and click Authorize. You should see a message confirming the authorization was successful.

Your computer is now authorized. You can close this dialog and start streaming your iTunes library to your Apple TV. The authorization stays active until you manually deauthorize the computer or change your Apple ID password.

What to Do Before You Start

Make sure both your computer and Apple TV are connected to the same Wi-Fi network. They don't have to be in the same room, but they need to be on the same network for streaming to work. Check your network settings on both devices if you're unsure.

Have your Apple ID and password ready. This is the account you use to purchase content from iTunes and the same one linked to your Apple TV. If you've forgotten your password, you can reset it on Apple's account recovery page before you begin the authorization process.

Update iTunes to the latest version available for your computer. Older versions of iTunes sometimes have trouble with authorization. On Mac, check the App Store for updates; on Windows, open iTunes and go to Help > Check for Updates.

Checking How Many Computers You've Authorized

You can see a list of all authorized computers linked to your Apple ID. Open iTunes, sign in with your Apple ID, and go to Account > View My Account. Scroll down to the section labeled Computer Authorizations or Authorized Computers. This shows how many of your five allowed authorizations you've used and lists the names of each authorized computer.

If you've reached the five-computer limit and need to authorize a new one, you'll have to deauthorize an old computer first. You can do this from the same account page by clicking Deauthorize next to the computer you no longer use. After deauthorizing, you can then authorize the new computer.

Deauthorizing a Computer You No Longer Use

If you're selling, giving away, or recycling a computer, deauthorize it before you hand it over. Open iTunes on that computer, sign in with your Apple ID, and go to Account > Authorize This Computer. Instead of "Authorize," the option will now say Deauthorize This Computer. Click it, enter your password, and confirm.

If you can't access the computer anymore—for example, if it's already gone or broken—you can deauthorize it remotely through your Apple ID account settings on Apple's website. Sign in, go to your account page, find the Computer Authorizations section, and click Deauthorize All. This removes all five authorizations at once, so you'll need to re-authorize your current computers afterward. Use this option only when necessary, since it affects all your authorized machines.

Troubleshooting Authorization Problems

If you see an error message saying you can't authorize, first check that you're using the correct Apple ID and password. A typo in either one will cause authorization to fail. Sign out of iTunes completely, then sign back in and try again.

If authorization still doesn't work, restart both your computer and your Apple TV. Unplug your Apple TV for 10 seconds, plug it back in, and wait for it to fully restart. Then try authorizing again. Sometimes a temporary connection issue between the devices prevents authorization from completing.

Make sure your computer's firewall isn't blocking iTunes. If you have third-party security software installed, check its settings to allow iTunes to communicate with Apple's servers. You may need to add iTunes to your firewall's whitelist or temporarily disable the firewall while authorizing.

If you've tried these steps and authorization still fails, sign out of your Apple ID in iTunes, restart your computer, and sign back in. This refreshes your connection to Apple's authorization servers and often resolves stubborn problems.

Frequently Asked Questions

Can I authorize a computer that's not on the same Wi-Fi as my Apple TV?

Yes. The authorization itself happens through your Apple ID account and doesn't require the devices to be on the same network. However, once authorized, your Apple TV will only be able to stream from that computer if both are on the same Wi-Fi network. Authorization is a one-time account setup; streaming is what requires the network connection.

What happens if I change my Apple ID password?

Your authorized computers will stop working until you sign in again with your new password in iTunes. Open iTunes, sign out, then sign back in with your new password. The authorization will reactivate automatically. You don't need to re-authorize the computer itself.

Can I authorize a computer on someone else's Apple ID?

Yes, but that computer will only stream content purchased under that Apple ID. If you want to stream your own iTunes library, you need to authorize using your own Apple ID. Each Apple ID has its own set of five authorized computers, so you can't mix libraries across different accounts on the same machine.

Do I need to authorize my computer every time I use Apple TV?

No. Once you authorize a computer, it stays authorized until you deauthorize it or change your Apple ID password. You won't see any authorization prompts after the first time. The authorization is permanent unless you manually remove it.

What if I forgot which computer is which in my authorized list?

The authorized computers list shows the name of each computer as it appears in your system settings. On Mac, this is the computer name in System Preferences > Sharing. On Windows, it's the device name in Settings > System > About. You can rename your computer to make it easier to identify in your Apple ID account, and the change will show up in your authorized list within a few hours.
