SiriMote Lets You Use Your New Apple TV Remote on Your Mac
Mac: The new remote that ships with the new Apple TV is awesome, but unlike the old remotes, it’s not easy to pair with your Mac. SiriMote is a simple little app that does just that.
SiriMote does not add any Siri functionality to the Apple TV Remote. Instead, it just adds the media control options that worked on the previous remote. This way you can play / pause music, change the volume and use it as a clicker for slides in Keynote. SiriMote requires El Capitan and a Mac with Bluetooth 4.0.
