I was interested in Nix because it could automate setup and configuration of macOS features. But all it does is usually run defaults or some intermediatary. In the end I stuck with brew and wrote an idempotent setupmac() function in my bash_profile (I use bash 5) with the aid of chatgpt since it knows all the cool defaults commands, and it’s pretty much solved setting up a new account or mac (alongside a Brewfile I maintain in my dotfiles). I don’t need any of those highfalutin tools.

I am, like, two minutes away from getting my configuration back on a fresh Mac or Linux system without Nix, so configuration management is just irrelevant to me. I am evaluating it as a package manager and a way to setup development environments.
