I've used it as my primary package manager on macOS for six months, but ended up dropping it.
My main reasons -
* Nix doesn't have support for GUI apps like homebrew cask does - which meant I couldn't drop homebrew anyway.
* The nix ecosystem forums suggest using nix-shell for managing packages for other languages, eg. python, java - but it's been really difficult to convince team members to use nix instead of pyenv, conda, gradle etc
