nix-config

nix-darwin, home-manager and dotfiles managed by nix.

Features

nix with nix flakes
nix-darwin
home-manager (via nix-darwin but could work as standalone too)
homebrew casks (via nix-darwin)
several dev-shells [WIP]

Machines

Host	Hardware	named after
`Kare`	Apple Laptop	Susan Kare
`Hopper`	Apple Laptop	Grace Hopper

My standard username is pw. All code will be placed in the ~/Documents/Code/weiland/ directory. Previously, all my code was stored in ~/src/weiland.

Installation

on a freshly clean mac machine

Setup machine

iCloud

During Setup:

Login in to iCloud
System Settings -> iCloud -> iCloud Drive: enable Desktop & Documents Folders.
Disable Optimize Mac Storage for Documents (and later in Photos, too), so all data will be downloaded.

System Updates

Making sure system is up-to-date:

sudo softwareupdate --install --all --restart --verbose

Xcode and Developer Tools

Install command line developer tools:

xcode-select --install

Then, install Xcode from the App Store.

Now, accept the Xcode and SDK license:

sudo xcodebuild -license accept

And make sure Xcode runs:

sudo xcodebuild -runFirstLaunch

Open Xcode go to Preferences, open the Platforms tab and download iOS and VisioOS Simulators.

Install Rosetta

Actually, I try to avoid it, but looking at you AusweisApp.app

softwareupdate –install-rosetta

Code directories

Create code directory:

mkdir -p ~/Documents/Code/weiland
mkdir ~/Documents/Code/clones
mkdir ~/Documents/Code/tests
mkdir ~/Documents/Code/go

Clone this nix-config

On a new system, the file modes might be lost, and have to be fixed so the keys can be accessed:

chmod 600 ~/Documents/Configs/ssh/id_pw

Now we can clone. In order to prevent password prompts and because there is no ~/.ssh directory yet with key pairs, we start with a different key path:

GIT_SSH_COMMAND='ssh -i ~/Documents/Configs/ssh/id_pw -o IdentitiesOnly=yes' git clone git@github.com:weiland/nix-config.git ~/Documents/Code/weiland/nix-config

other ways to clone (if ssh keys or GitHub are already setup):

# using ssh (with default key in ~/.ssh)
git clone git@github.com:weiland/nix-config.git ~/Documents/Code/weiland/nix-config

# or using default (i.e. login to GitHub)
git clone https://github.com/weiland/nix-config.git ~/Documents/Code/weiland/nix-config

If there is no git ...

(which is supposed to be there actually with ventura/sonoma and installed xcode dev-tools)

You can follow the next step and install nix and then you can create a nix shell with git installed temporarely:

nix run nixpkgs#git

# or via old nix-env command
nix-env -iA nixpkgs.git

And now cd into the newly cloned nix-config directory:

$ cd ~/Documents/Code/weiland/nix-config

Install nix package manager

Via the official nix installer:

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

Or using Determinate Nix Install / fish shell installation

Or using The Determinate Nix Installer, which performs well on mac (esp. after mac upgrades) and brings flake support by default:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

If already in the fish shell:

sh (curl -L https://nixos.org/nix/install | psub)

Enable flakes via config file

Not needed when using my home-manager config (or the Determinate Nix installer).

mkdir -p ~/.config/nix
echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf

Install Homebrew

It can run independently but is later controlled via nix-darwin.

bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

The brew command will ba available later after applying the home-manager settings.

Install mac with nix-darwin

This will apply the nix-darwin config and the home-manager config, so all mac default preferences will be set as well as all apps, tools and binaries will be installed.

# making sure to be in the right directory
cd ~/Documents/Code/weiland/nix-config

The following commands will install the host Hopper. Which can be replaced with any other hostname that exists in the ./hosts/ directory.

nix run --extra-experimental-features "nix-command flakes" nix-darwin -- switch --flake .#Hopper

You have to enter your sudo password (at least once, perhaps more often as longer it takes) and click on Allow when prompted.

Or if using flakes remotely:

TODO(weiland): Fix command below

nix flake --extra-experimental-features 'nix-command flakes' init -t github:weiland/nix-config#darwin

The next step is to restart the mac:

sudo reboot

Now nix-command and flakes are enabled by default, so --extra-experimental-features can be omitted.

Update / Rebuild

Run again:

nix run nix-darwin -- switch --flake .#Hopper

# for further times, one can use in any directory:
nix run nix-darwin -- switch --flake ~/.config/nix-darwin#Hopper

(Perhaps Full Disk Access is required. Enabled it in the Privacy & Security System Settings for the current Terminal.)

Finalisation / App Preferences

iterm

re-use config from `data/iterm/`

Set config:

$ defaults write com.googlecode.iterm2 PrefsCustomFolder "/Users/pw/Documents/Code/nix-config/data/iterm"

Alternatively:

Open iterm2
General -> Preferences -> check Load preferences from a custom folder or URL
choose /Users/pw/Documents/Code/weiland/nix-config/data/iterm
And don't overwrite the existing one.

Generally, allow Full Disk Access for iTerm in System Settings -> Privacy & Security

For pre Sonoma:

If no directory can be selected, iterm has no access to the hard disk. This can be fixed by open `System Settings` -> Privacy & Security -> Hard Disk Access -> add _iterm2.app_.

Import a new colorscheme

#### Use a different colorscheme

Set colorscheme:

open ~/Documents/Code/weiland/nix-config/data/iterm/Oceanic-Next.itermcolors

Open any other additional itermcolors-file.

Other colorschemes for iterm can be found at: https://iterm2colorschemes.com and should be downloaded to data/iterm/.
