Archived - Apple TV (1st generation): Firewall alert appears in iTunes

This article has been archived and is no longer updated by Apple.

Symptoms

If you've enabled the Mac OS X built-in firewall with certain options, or have configured third-party firewall software in certain ways, connections to Apple TV (1st generation) may not work if certain ports are blocked. As a result, these issues may occur:

  • iTunes states that "Your computer's firewall settings prevent you from using some iTunes features."
  • If you try to sync content your Apple TV (1st generation), this alert appears in iTunes: "The Apple TV '(Your Apple TV's name)' is not responding.  Check that any firewall software running on this computer has been set to allow communication on port 3689."

Note: If you are using Microsoft Windows instead of Mac OS X, see "Apple TV: 'Check that any firewall software running on this computer has been set to allow communication on port 3689' alert in Windows" for more information.

Resolution

Third-party firewall software

Port-based, third-party Internet security/firewall software may cause communication issues between your Apple TV and your Mac if the correct ports are not open. This includes products such as Little Snitch by Objective Development, Internet Security Barrier by Intego, or Norton Internet Security for Mac by Symantec.

Consult the product's documentation, contact their support staff, or visit their support website for details and assistance.
 

Mac OS X v10.6 or later firewall

  1. From the Apple () menu, choose System Preferences.
  2. From the View menu, choose Security.
  3. Click the Firewall pane.
  4. Either click Stop to stop the firewall entirely, or click the Advanced button and ensure that "Block all incoming connections" is not enabled.

The other firewall options will not prevent Apple TV (1st generation) from communicating with your Mac.

 

Mac OS X v10.5.x firewall

  1. From the Apple () menu, choose System Preferences.
  2. From the View menu, choose Security.
  3. Click the Firewall pane.
  4. Either click Stop to stop the firewall entirely, or click the Advanced button and ensure that "Allow only essential services" is not enabled.

The other firewall options will not prevent Apple TV (1st generation) from communicating with your Mac.

For Mac OS X v10.4 or earlier firewall

  1. From the Apple () menu, choose System Preferences.
  2. From the View menu, choose Sharing.
  3. In the "Allow" field make sure the "iTunes Music Sharing" check box is checked. This will allow the transfer of content for syncing and or streaming to your Apple TV.

Note: If you use Fast User Switching on a Mac with the firewall enabled, you'll need to enable additional ports to allow streaming to Apple TV (1st generation). If you don't, only the first user will be able to stream to Apple TV. For one additional user enable TCP port 49152. For each additional user, open the next incremental port (49153 for three users, 49154 for four users, 49155 for five users, and so forth).

Follow these steps to add the necessary ports:

  1. Choose Apple > System Preferences.
  2. Choose View > Sharing.
  3. Click the Firewall tab.
  4. Click New.

  5. From the Port Name pop-up menu, choose Other.
  6. In the TCP Port Number(s) field, type in:

    49152, 49153

    Note: This example allows for a total of three users. If you need more, enter the additional number(s) as described in the note above. If you need fewer, just enter the first number.
     
  7. In the Description field type in: Extra Apple TV Streams
  8. Click OK.

Additional Information

If iTunes continues to display one of the alerts with an Apple TV (1st generation) even though the Mac firewall is configured properly, and there is no third-party firewall software, there may be a network issue.
