Hi @Hawk1
The Masuter Pro runs standard GRBL 1.1, so it is supported by LightBurn.
If you want to try an earlier version of LightBurn on macOS, all previous builds are kept here:

On macOS it’s also worth checking the Laser window → Port dropdown. If you only see cu.Bluetooth-Incoming-Port, the Mac isn’t detecting the controller. Most FoxAlien boards use a CH340/CH341 USB chip, so you may need the driver.
There’s a thread with the Mac driver link here:
