dotfiles

M1 macOS (nix-darwin) config, managed with a flake and home-manager.

macOS (M1) — nix-darwin

Apply

# Enable flakes if you haven't:
mkdir -p ~/.config/nix
echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf

# First run: bootstraps darwin-rebuild, then applies system + user.
sudo nix run nix-darwin/master#darwin-rebuild -- switch --flake ~/dotfiles#<user>

After the first run, re-apply with (aliased to rebuild):

sudo darwin-rebuild switch --flake ~/dotfiles#<user>

User-only changes (no sudo):

home-manager switch --flake ~/dotfiles#<user>@mac    # aliased to `rebuild-home`

Remove

sudo nix run nix-darwin#darwin-uninstaller          # removes nix-darwin

Stock files it replaced are backed up next to the originals as .before-nix-darwin / .hm-bak; restore those if needed, then delete ~/dotfiles.
