ChibiOS Free Embedded RTOS

I've was able to successfully complete till step 3.4.1, I couldn't find a MSYS2 tool equivalent for MAC. Could you please help on alternatives for MSYS2 for MAC for further proceedings.

Hey I'm familiar with chibistudio with Windows OS, can you please guide me through on how to get started with Chibistudio on Mac?
I'm not sure whether Chibistudio for MAC is available or should we configure chibios with Cubeide or Eclipse.

Expecting your helpful feedback,
