I've tried nix-darwin a time or two in the past. Every few years when homebrew makes a "hostile" change and I get upset I consider trying it again (now most recently with changes to gatekeeper). I think I'll get to doing so in the next year or so.

But I think just in fairness, the comparison here for flakes should be to Homebrew bundles. My packages are managed in a bundle: https://github.com/Julian/dotfiles/blob/main/Brewfile and then locked by a lockfile: https://github.com/Julian/dotfiles/blob/main/Brewfile.lock.j... and installing is just `brew bundle install`. All native Homebrew functionality. In practice I have never had an issue with non-reproducible builds across my machines (partly because the tendency on macOS is to run the latest versions of things and stay up to date).

(But again I do find nix-darwin interesting to try for other reasons.)

Very nice, I think I'll be moving my "must-have" homebrew packages to a Brewfile. FYI tho, Homebrew no longer supports Brewfile.lock.json (it was always just a log anyway, not a lockfile). https://github.com/Homebrew/homebrew-bundle/pull/1509

Fun, thanks for letting me know, will remove it :)

(I'll still stick with "I never really have run into a version issue for things I use Homebrew for, for places where it matters, I have whatever-programming-language-lockfile-for-the-project-I-am-developing" for cases where I need to be sure the setup is reproducible, which is why I've clearly never noticed this file was useless).

The bundler integration for nix-darwin actually just bakes tightly-controlled Brewfiles. It’s still worthwhile though, since part of the “tightly-controlled” means better cleanup when you remove things.
