Setup

macOS

Note

If you're using Alfred, to make Applications installed via Nix to appear on Alfred:

• Open Alfred Preferences
• General > Default Results > Extras > Click Advanced
• Add com.apple.alias-file

Caution

This setup is NOT compatible with homebrew, it is designed to completely replaces homebrew. Uninstall homebrew before proceeding.

Nix in macOS is handled by nix-darwin.

Initial

This is done because nix-darwin commands is not yet added to PATH, should be a one-time thing

nix-env -iA nixpkgs.git
# Run `sudo chown $USER /nix/var/nix/profiles/per-user/$USER` if that returns error

nix build .#darwinConfigurations.<host>.system

./result/sw/bin/darwin-rebuild switch --flake .#<host>
# or
nix run nix-darwin -- switch --flake .#<host>

Rebuild

After initial setup, you should now be able to use the command directly:

darwin-rebuild build --flake .  # or you can specify the hostname with `--flake . #<hostname>`

# or if you're feeling lucky

darwin-rebuild switch --flake .

Other

Nix in non-NixOS Linux is handled by system-manager.

Rebuild

Unfortunately, root access is required in order to use system-manager.

sudo -i nix run 'github:numtide/system-manager' --extra-experimental-features "nix-command flakes" -- switch --flake $PWD

Home

This is for per-user setup. Instead of managing the entire system, you're managing one user at a time. This is handled by home-manager

Rebuild

home-manager build --flake .  # or you can specify the user with `--flake . #<username>@<hostname>`

# or if you're feeling lucky

home-manager switch --flake .
