Yes, unfortunately it only works on Linux and FreeBSD. I should add that to the readme.

EDIT: Added.

Why, though?

Because I'm just one guy with a few people helping me a little bit. I needed a limited scope. But I'm actually thinking of porting it to Mac now.

I don’t think you need to port that much as macOS is based om freeBSD

Cus they like Stallman too much
