Installing E-Stim Commander on a Mac

Category: Commander

Commander 3 is the software that allows you to connect an E-Stim Systems 2B to a PC or Mac, and thus allow you to control the 2B from the computer, as well as record and playback 'sessions'.

Although Commander 3 was originally developed on a Mac running macOS High Sierra, It has also been tested on Catalina and Big Sur, with the new M1 hardware. it should also operate correctly on older versions of macOS. If has also been tested on Windows 10, Windows 7, and should work on Windows 8 and 8.1. We also offer Commander 3 for Linux, although the Linux version is not actively supported at this time.


Which Version?

Commander 3 is designed to operate with E-Stim Systems 2B running 2.106 firmware and below. Commander 4 is designed to operate with 2B's running firmware 2.2. and above. If you are not sure which firmware your 2B is running, we have a video on how to check what firmware version your 2B is running.
