To get started on a bare macOS installation, first install Nix:
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
Launch a new shell. Then use Nix to switch to the macOS configuration:
sudo rm /etc/bashrc
sudo rm /etc/nix/nix.conf
nix \
--extra-experimental-features flakes \
--extra-experimental-features nix-command \
run nix-darwin -- switch \
--flake github:chrishrb/nix-dots#mw
Once installed, you can continue to update the macOS configuration:
nix run nix-darwin -- switch --flake ".#mw"
Manually install the german programming keyboard.
