Download of xMaster 2.1.4 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally developed by Art Coughlin. The application belongs to Lifestyle Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
xMaster is a schedule manager for the X-10 model CP290 computer interface. Use xMaster to create and edit schedules of events that can be stored in the CP290's memory, or saved to disk. Retrieve events from the CP290. Have different schedules automatically loaded to the CP290 on specific dates.
You may want to check out more Mac applications, such as BookTracker, Statistics Pro Demo or Reunion, which might be similar to xMaster.
