This repo stores my NixOS and Nix on Darwin setup.
NixOS configs are here: ./nixos
Nix on Darwin configs are here: ./darwin
My custom modules expose a heywoodlh configuration parameter. Here's an incomplete example snippet for using my modules in a flake:
{
description = "heywoodlh nix config";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";
darwin.url = "github:LnL7/nix-darwin/master";
heywoodlh-configs.url = "/Users/heywoodlh/opt/nixos-configs";
};
outputs = inputs@{ self, nixpkgs, darwin, heywoodlh-configs, ... }: {
darwinConfigurations = let
heywoodlh-darwin-modules = (heywoodlh-configs "/darwin/modules/default.nix");
in {
"my-macbook" = darwin.lib.darwinSystem {
system = "aarch64-darwin";
specialArgs = inputs;
modules = [
heywoodlh-darwin-modules
{
networking.hostName = "my-macbook";
heywoodlh.darwin.sketchybar.enable = true;
heywoodlh.darwin.yabai.enable = true;
system.stateVersion = 4;
}
];
};
};
};
}
Documentation for module options can be viewed here: options.md
Check out the outputs for this flake with this command:
nix flake show github:heywoodlh/nixos-configs
For some reason, the darwinConfigurations outputs aren't shown properly, so you'll have to manually check out ./flake.nix to figure out what MacOS outputs are available.
To install a NixOS configuration, let's assume the nixos-desktop-intel output, do the following:
sudo nixos-rebuild switch --flake github:heywoodlh/nixos-configs#nixos-desktop-intel
For VMs, use the NixOS graphical installer.
Then run the install on the virtual machine:
sudo nixos-rebuild switch --flake github:heywoodlh/nixos-configs#nixos-vmware --impure
Make the following settings changes to the VM in VMWare Fusion:
Display:
- Accelerate 3D Graphics
- Shared graphics memory => maximum
- Use full resolution for Retina display
Keyboard and Mouse:
- Disable all host keybindings
Remove the Camera and Sound devices
Sharing:
- Enable Shared Folders
- Add MacOS
$HOME
- Add MacOS
Use the following settings when setting up the VM:
Virtualize > Use Apple Virtualization > Enable Rosetta (x86_64 Emulation)
Use the copy-to-ram install option, then run through the graphical installer.
After the install, run the following command:
sudo nixos-rebuild switch --flake github:heywoodlh/nixos-configs#nixos-utm --impure
To install a MacOS configuration, let's assume the m3-macbook-pro output, do the following:
nix run "github:LNL7/nix-darwin#packages.aarch64-darwin.darwin-rebuild" -- switch --flake github:heywoodlh/nixos-configs#m3-macbook-pro --impure
Run the following command to use the Home Manager implementation on any Linux distribution with nix installed:
nix --extra-experimental-features 'nix-command flakes' run github:heywoodlh/nixos-configs#homeConfigurations.heywoodlh.activationPackage --impure
For headless Linux machines:
nix --extra-experimental-features 'nix-command flakes' run github:heywoodlh/nixos-configs#homeConfigurations.heywoodlh-server.activationPackage --impure
