Mac: The new remote that comes with the new Apple TV is cool, but unlike older remotes, it doesn’t easily pair with your Mac. SiriMote is a simple little app that’ll do just that.
SiriMote does not add in any of the Siri functions of the Apple TV Remote. Instead, it just adds in the media control options that worked on the previous remote. So, you can play/pause music, change volume, and use it as a clicker for slides in Keynote. SiriMote requires El Capitan and a Mac with Bluetooth 4.0 to work.
