The last time I tried (a month ago), I could reproduce most of my current Homebrew packages. There are few that are broken (e.g. rust, which has since been fixed), or do not have Darwin support (aria2c, which I have a PR open[1]). There are also packages that are a little bit hard to discover, e.g. those that are imported from Haskell's Hackage where it is not listed by default[2] when you do `nix-env -i <packageName>` (e.g. shellcheck). From my few days of trying to replace Homebrew with Nix, being able to rollback the environment to last known good state (`nix-env --rollback`), ability to keep track of package changes (`nix-env --list-generations`), ability to try a package without installing it (`nix-shell`, well, technically it's installed on the machine, but nothing is linked in the profile, and you can nuke them with `nix-collect-garbage`) are very nice additions. Apart from these features, the fact that it doesn't chown `/usr/local/` to my user is a big plus. Nix will also not linking anything not explicitly installed by user to their profile (e.g. if package A has B as dependency, B won't be linked until user actually choose to install it, which is then managed separately from B that were explicitly installed as A's dependency). That said, I've since revert back to Homebrew because there are few packages broken that are crucial to what I'm working on. Creating and fixing package is not too hard (I did with aria2c), although time didn't allow me to do it back then. I would love to try to switch to Nix again sometimes. People in ##nix-darwin are super-nice, also! :-) [1]: https://github.com/NixOS/nixpkgs/pull/15029 https://github.com/NixOS/nixpkgs/pull/15029 [2]: https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell...
