Looking in activities.py, I see a some functions that are OS-agnostic, but also a ton of functions that are Windows-specific in terms of process names and paths, and directly referencing the win32 lib. It's a matter of "unsupported" meaning "impossible" rather than "you're on your own". That said, the code is pretty easy to read, and would make for a good starting point to make your own automation library.

Yeah indeed. It works, but not all of their activities work on Mac OS
