Installation - Mac

To install on a Mac OS X system, first download the file from the Downloads page on the RJM Music website. Before downloading, make sure the correct product is selected in the bar above the list of releases. 

Important note: The editor version needs to match the first two numbers of your product's firmware version. For example, If you have firmware version 4.6.1, the editor needs to be version 4.6.x. In general, it's best to have the latest firmware and editor version. Your Mastermind's firmware version is displayed in bottom right corner of the main LCD display for 2 seconds on power up.

Double-click the .dmg file that was downloaded, and it will open up a window showing the Editor app and a link to the Applications folder. Drag the editor app file to the Applications folder to install.


To run, open up your Applications folder, where you'll find the MMGTEditor or MastermindEditor file. Double click the file and the editor will start up.
