Pair or unpair an Apple Remote with Mac
If you have more than one computer with a built-in infrared (IR) receiver in the same room, you’ll probably want to pair each computer with a specific Apple Remote. Pairing sets the computer to take commands only from the specified remote. You can pair your computer with only one remote at a time. You must remove the pairing before you can use a different remote with the computer.
Pair an Apple Remote
Hold the remote close to the computer (3 to 4 inches away) and point the remote at the front of the computer.
Pair the Apple Remote by doing one of the following:
Apple Remote with seven buttons: Press and hold both the Right and Menu buttons on the remote until the paired-remote icon appears on the screen of your computer (about 5 seconds).
Apple Remote with six buttons: Press and hold both the Next and Menu buttons on the remote until the paired-remote icon appears on the screen of your computer (about 5 seconds).
Unpair an Apple Remote
On your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click General.
Click the lock icon to unlock it, then enter an administrator name and password.
In the window that appears, click Unpair.
If your computer is not paired with a remote, the computer will take commands from any remote within range (up to 30 feet), even if the remote is paired with another computer.
