Prerequisites

• macOS (Apple Silicon)
• Git

Installation

# 1. Install Nix
sh <(curl --proto '=https' --tlsv1.2 -L https://nixos.org/nix/install)
2. Clone dotfiles (use nix-shell if git is not installed)
nix-shell -p git --run "git clone https://github.com/mozumasu/dotfiles ~/dotfiles"
3. Backup existing shell configs (first time only)
sudo mv /etc/bashrc /etc/bashrc.before-nix-darwin
sudo mv /etc/zshrc /etc/zshrc.before-nix-darwin
4. Apply nix-darwin configuration (first time)
Note: $HOME is expanded before sudo runs, so the path is correct
Replace <hostname> with your host name (geisha, bourbon, etc.)
sudo nix run \
  --extra-experimental-features nix-command \
  --extra-experimental-features flakes \
  nix-darwin -- switch --flake "$HOME/dotfiles/.config/nix#<hostname>"
After initial setup, use:
nix-switch (or darwin-rebuild switch --flake ~/dotfiles/.config/nix#<hostname>)
