It does. It lets nix run your machine configuration declaratively, like nixos. Ive never done much macOS, but i'd be worried about apple making it hard in a future release--the hardware isnt open source so they could rug u. Youre also at the mercy of nix devs handling support if anything breaks.

imo best to spin up a beefy nixos vm, manage it with nixos declaratively, and get best of both worlds.

Or get a thinkpad ;)
