nix-config

My Nix Configuration for macOS using nix-darwin and home-manager.

Supports both Apple Silicon and Intel Macs, with multi-user support for shared machines.

Quick Start

# First time setup (after installing Nix)
nix run nix-darwin -- switch --flake ~/.config/nixpkgs#<config-name>

# Subsequent rebuilds
darwin-rebuild switch --flake ~/.config/nixpkgs#<config-name>

Available configurations: salarm3max (Apple Silicon), salarintel (Intel)

User Profiles

User-specific settings (name, email, etc.) are stored in users/*.nix files.

Example user profile (users/myusername.nix):

{
  username = "myusername";
  fullName = "My Full Name";
  email = "me@example.com";
  gitSigningKey = "~/.ssh/id_ed25519.pub";  # or null if not using signing
  jujutsuBranchPrefix = "myprefix";
}

Then reference it in your machine configuration in flake.nix:

myMachine = mkDarwinConfig {
  system = "aarch64-darwin";
  hostname = "my-machine";
  users = [ (import ./users/myusername.nix) ];
};

For shared machines with multiple users:

sharedMachine = mkDarwinConfig {
  system = "aarch64-darwin";
  hostname = "shared-machine";
  users = [
    (import ./users/user1.nix)
    (import ./users/user2.nix)
  ];
};
