nix-darwin
Nix modules for darwin, /etc/nixos/configuration.nix
for macOS.
This will creates and manages a system profile in /run/current-system
, just like nixos.
The default NIX_PATH
in nix-darwin will look for this repository in ~/.nix-defexpr/darwin
and for your configuration in ~/.nixpkgs/darwin-configuration.nix
.
If you want to change these you can set your own with nix.nixPath = [ ];
.
$ darwin-rebuild switch

$
$ darwin-option services.activate-system.enable ~/src/nix-darwin
Value:
true
Default:
false
Example:
no example
Description:
Whether to activate system at boot time.
Install
This will link the system profile to /run/current-system
, you have to create /run
or symlink it to private/var/run
.
If you use a symlink you'll probably also want to add services.activate-system.enable = true;
to your configuration.
NOTE: the system activation scripts don't overrwrite existing etc files, etc files like
/etc/bashrc
won't be used by default. Either modify the existing file to source/import the one from/etc/static
or remove it.
# install nixpkgs version, this enables libsodium support (for signed binary caches)
# this is not required if you already upgraded nix at some point
nix-env -iA nixpkgs.nix
sudo ln -s private/var/run /run
git clone git@github.com:LnL7/nix-darwin.git ~/.nix-defexpr/darwin
cp ~/.nix-defexpr/darwin/modules/examples/simple.nix ~/.nixpkgs/darwin-configuration.nix
# bootstrap build using default nix.nixPath
export NIX_PATH=darwin=$HOME/.nix-defexpr/darwin:darwin-config=$HOME/.nixpkgs/darwin-configuration.nix:$NIX_PATH
# you can also use this to rebootstrap nix-darwin in case
# darwin-rebuild is to old to activate the system.
$(nix-build '<darwin>' -A system --no-out-link)/sw/bin/darwin-rebuild build
$(nix-build '<darwin>' -A system --no-out-link)/sw/bin/darwin-rebuild switch
. /etc/static/bashrc
Example configuration
Checkout modules/examples for some example configurations.
{ pkgs, ... }:
{
# List packages installed in system profile. To search by name, run:
# $ nix-env -qaP | grep wget
environment.systemPackages =
[ pkgs.nix-repl
];
# Create /etc/bashrc that loads the nix-darwin environment.
programs.bash.enable = true;
# Recreate /run/current-system symlink after boot.
services.activate-system.enable = true;
}
Modules
system.defaults
A set of modules to manage macOS settings.
{
system.defaults.dock.autohide = true;
system.defaults.dock.orientation = "left";
system.defaults.dock.showhidden = true;
}
NOTE: you have to restart the dock in order for these changes to apply.
killall Dock
environment.etc
Set of files to be linked in /etc
, this won't overwrite any existing files.
Either modify the existing file to source/import the one from /etc/static
or remove it.
{
environment.etc."foorc".text = ''
export FOO=1
if test -f /etc/foorc.local; then
. /etc/foorc.local

# Global user configuration, symlink these to the appropriate file:
# $ ln -s /etc/static/per-user/lnl/gitconfig ~/.gitconfig
environment.etc."per-user/lnl/gitconfig".text = ''
[include]
path = .gitconfig.local
[color]
ui = auto
'';
}
launchd.daemons
Definition of launchd agents/daemons. The serviceConfig options are used to generate the launchd plist file.
{
launchd.daemons.foo = {
serviceConfig.ProgramArguments = [ "/usr/bin/touch" "/tmp/foo.lock" ];
serviceConfig.RunAtLoad = true;
};
}
services
A set of modules for predefined services, these generate the appropriate launchd daemons for you.
{
services.nix-daemon.enable = true;
services.nix-daemon.tempDir = "/nix/tmp";
}
programs
A set of modules to manage configuration of certain programs.
{ pkgs, ... }:
{
environment.shellAliases.ls = "${pkgs.coreutils}/bin/ls";
programs.bash.enable = true;
programs.vim.enable = true;
programs.vim.enableSensible = true;
}
nixpkgs.config
This attribute set is used as nixpkgs configuration when using nix-darwin.
{
environment.systemPackages =
[ # Use vim_configurable from packageOverrides
lnl.vim
];
nixpkgs.config.allowUnfree = true;
nixpkgs.config.packageOverrides = pkgs: {
lnl.vim = pkgs.vim_configurable.customize {
name = "vim";
