These are my dotfiles. There are many like them, but these are mine.

On a new mac, you might need to install git.

xcode-select --install

Verify the installation by running

xcode-select -p

should output the following

/Library/Developer/CommandLineTools

Clone this repo. It might be a good idea to clone using HTTPS if you don’t have your SSH keys configured. I store my SSH key on a Yubikey for portability but that setup relies on some of the stuff that’s configured in here. HTTPS is a safe bet. You can always fix your local git config later on using something like

git config [email protected]:.insteadof https://github.com/

In order to perform a multi-user install of nix on macOS, follow these steps.

The first order of business is to make sure diskutil is in your $PATH. If it isn’t, execute

export PATH=/usr/sbin:$PATH

to add it. Now you can go ahead and run the installer

sh <(curl -L https://nixos.org/nix/install) --daemon

This should take you throught the process in a nice and straight-forward way. Once the installation finishes, you can verify it by opening a new terminal, and executing

nix-shell -p nix-info --run "nix-info -m"

It’s possible that this won’t work straight away, and you may get something like

error: could not set permissions on '/nix/var/nix/profiles/per-user' to 755: Operation not permitted

Don’t worry. The issue is very likely that the nix-daemon isn’t up and running just yet. Give it a few seconds and try again.

With Nix installed, we’re ready to bootstrap and install the actual configuration. Flakes is finally supported in the latest versions of Nix, so from the root of the checkout out repo we should be able to go ahead and run

nix build \
	--extra-experimental-features nix-command \
	--extra-experimental-features flakes \
	.#darwinConfigurations.bootstrap-x86.system
./result/sw/bin/darwin-rebuild switch --flake .#bootstrap-x86

Then open up a new terminal session and run

darwin-rebuild switch --flake .#macbook

Tada! Everything should be installed and ready to go.
