My MacOS machines as code

This repository aims to provide full declarative configurations for my MacOS machines.

Base Features

• System: Nix-darwin for declarative MacOS configuration.
• User Management: Home Manager integration for user-specific packages and dotfiles.
• Homebrew: nix-homebrew for declarative management of Casks and formulae.

Prerequisites

• macOS only: This configuration is designed specifically for macOS (Darwin)
• sudo access: The installation requires administrator privileges
• Fresh install recommended: While this can be run on an existing system, it will modify system-level configurations

Installation

Run this one-liner to automatically install everything:

curl -fsSL https://raw.githubusercontent.com/dsalaza4/env/main/install.sh | zsh -- <machine>

Where <machine> is the name of the machine you want to install. personal will be used by default.

This script will:

1. Install Determinate Nix (if not already installed)
2. Clone this repository to a temporary directory
3. Run the nix-darwin configuration to set up your system

Usage

After installation, you can manage your system configuration using the included justfile commands:

Available Commands

• just build [MACHINE] (or just b [MACHINE]): Rebuild the system configuration

  just build           # Rebuilds the personal machine (default)
  just build work      # Rebuilds the work machine

  Use this after making changes to your configuration files.

• just update (or just u): Update flake dependencies

  just update

  This updates all Nix flake inputs to their latest versions.

Managing Multiple Machines

This repository supports multiple machine configurations under machines/:

• machines/personal/ - Your personal machine (default)
• machines/test/ - CI test configuration

To add a new machine:

1. Copy machines/personal/ to machines/<name>/
2. Customize the configuration in machines/<name>/
3. Add a new darwinConfigurations.<name> entry in flake.nix
4. Build with just build <name>

Making Changes

1. Edit configuration files in this repository
2. Run just build to apply changes (or just build <machine> for a specific machine)
3. Commit and push your changes to keep them synchronized

Missing features

1. Docker Desktop: Not available via nixpkgs or homebrew.
