based on the Nix documentation the macOS situation does not look as positive as described by this comment:

- if you have an M1 mac, it does not work (https://github.com/NixOS/nixpkgs/issues/95903)

- if you have an intel mac, when you install it, you have to add the "--darwin-use-unencrypted-nix-store-volume" switch to the installer, otherwise it does not work (https://nixos.org/manual/nix/stable/#sect-macos-installation). i do not want unencrypted things on may computer. (and yes, there is a long section of the documentation about other approaches with other tradeoffs, and if you have a T2 chip then maybe it is ok (but why isn't the installer detecting this automatically?)... the point is, with homebrew there is no such problem)
