+The reason you are still seeing command not found is that darwin-rebuild does not exist on your computer yet.When doing a brand-new installation of nix-darwin, the darwin-rebuild tool is not part of the standard Nix installer. You have to bootstrap it using the nix run command first, which will dynamically pull the tool from GitHub and execute the initial build.Run the following command from your terminal inside your ~/.dotfiles directory:zshsudo nix run nix-darwin#darwin-rebuild -- switch --flake ~/.dotfiles#lt-mbp
