Nix-Darwin Environment Setup

This repository contains the configuration for a reproducible computer environment using nix-darwin for macOS nix modules. For more information, visit the nix-darwin GitHub repository.

Setup for a New Computer

1. Install Nix

2. Replace the location of the flake:

   sed -i '' "s/simple/$(scutil --get LocalHostName)/" flake.nix

3. Determine the correct hostPlatform for Mac architecture in flake.nix:

   • For Intel Macs: nixpkgs.hostPlatform = "x86_64-darwin";
   • For Apple Silicon Macs: nixpkgs.hostPlatform = "aarch64-darwin";

Installing a Package

1. To search for packages, use https://search.nixos.org/packages
2. Add the package to flake.nix in the environment.systemPackages list
3. Run the following command:

   darwin-rebuild switch --flake .#MacBook-Pro-Work
   

Updating a Package

To update packages, run the following commands:

nix flake update
darwin-rebuild switch --flake .#MacBook-Pro-Work

Updating nix-darwin

To update nix-darwin itself, use these commands:

nix-channel --update darwin
darwin-rebuild changelog

Note

This setup doesn't use nix-homebrew, as it's still an early project.
