My macOS configuration managed with nix-darwin + home-manager.

Structure

• flake.nix - Main entry point
• nix-darwin/configuration.nix - System settings
• nix-darwin/homebrew.nix - Homebrew casks and brews
• home-manager/home.nix - Packages and program configuration

2. Clone this repository:

   git clone https://github.com/t3yamoto/dotfiles ~/dev/github.com/t3yamoto/dotfiles
   cd ~/dev/github.com/t3yamoto/dotfiles

3. Apply the configuration:

   sudo darwin-rebuild switch --flake .

4. Set up manually managed files:
