Mbot cubeGrid new firmware

Hey. I have an Mbot cube, and also have the Grid 2 upgrade pack for it. now i’m wanna upgrade the firmware so i actually have the auto bed leveling… and not just 3 holes in the bed to calibrate it manual. thats just not autlo leveling…

I saw that sailfish 7.7 have support for this and i also found a Gihub link https://github.com/MBot3D/MBotFirmware/tree/master/Firmware%20for%20CubeGrid2

With som thing that looks like a firmware for my printer and 7.7, can some one help me compile it. is it possible from mac? or do i need linux, is there another way to install 7.7 without using the github thing?

Thanks.BR Patrik
