Unified configuration for macOS and Linux systems from a single point of control

• Darwin (macOS)

  • 2021 M1 Max MacBook Pro (16")
  • 2024 M4 Max MacBook Pro (16") (WIP)

• Linux (NixOS)

  • HP ZBook Firefly 14 G7 (WIP)

• Darwin (macOS)

  • Use the Determinate Systems Nix Installer to install Nix on macOS
  • For the first run, use nix -v run

• Linux (nixOS)

  For an existing system, use sudo nixos-rebuild switch --flake .

  (fresh install instruction wip)

After changes are made:

nh (os|darwin) switch -a . # os for NixOS, darwin for macOS

• Enter the dev environment with nix develop (or direnv allow if you use direnv).
• Run uv sync once to create .venv; .envrc will auto-activate it when present.
• Repo CLI (update/CI helpers): nix run .#nixcfg -- update --help and nix run .#nixcfg -- ci --help.
