Do you run Nix on the macOS side? How would you summarize your experience? Is it worth investing time/effort into it, considering you're also using NixOS?
You might as well also run Nix on macOS as well and extract out the common parts of your config (selection of CLI software, at least), right? I'd do that even if macOS was just a seldom-used 'backup OS'.
I do run nix on the macos side, for graphics apps like a browser I would not recommend. But for command line apps like interpreters, compilers and vim-like editors it is really useful imho.
