Recent Mac computers come with a handy remote control. This remote let’s you interact with programs like FrontRow, iTunes, iPhoto and it can even be used as a remote for Keynote.
However, if you have two or more Macs close to each other, both Macs will respond to any button pressed on the Apple Remote Control. This is because by default, your Mac will respond to any Apple Remote.
Luckily you can change this behaviour by pairing each Apple Remote with one specific Mac. You can do this by holding the remote close to the Mac you want it to pair to while pressing the Menu and Next buttons simultaneously for about 5 seconds. A remote icon should appear on your screen when the pairing process was successful.
One thing you might want to do is temporarily disable the IR port on the other Macs by going to System Preferences and the Security pane. On the General tab, there’s a checkbox option which allows you to disable the IR receiver on your Mac. When you’re done, you can switch the IR receiver back on by unchecking the same checkbox.
