Flirc is the companion utility for your Flirc device, a tool designed to enable you to quickly setup any remote controller device to be used with your Mac’s media center.
Really, really cool little app/USB dongle system. Since Apple nixed the IR remotes on new Macs if you want that functionality you have to get a third party solution. This is exactly where FLIRC comes in. With the app/dongle and nearly any remote you are back in business. Really helpful!
