From the developer:
KeyShowX is a simple, yet powerful, tool for making multi-screen presentations, shows and digital signage. It is a companion product for Apple Keynote and Microsoft PowerPoint on MacOS. Consider it as a universal, flexible and scriptable remote control unit for simultaneous execution and synchronization of multiple presentations running on different computers.
You may want to check out more software for Mac, such as PCR Editor, Vvidget or S90 ES Mix Editor, which might be similar to KeyShowX.
