App Casting, stream the screen of any of your Mac (10.9) App to your favorite media player.
LeanBack is a Mac freeware (no spyware/malware) that enables you to cast any of your Mac applications (as long as it is running and not minimized) to a HLS-enabled media player (devices and applications that support the HLS format). You may have read about the Chromecast "tab casting" feature. Well, why should we be limited to casting only the Chrome browser tab? LeanBack is the answer!
