Development Environment Setup

macOS

Install Nix using nix-installer:

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

Install Homebrew:

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

Bootstrap nix-darwin:

nix build .#darwinConfigurations.${hostname}.system

# Create a symlink from /run to /private/var/run required by nix-darwin. This step is needed since macOS does not allow any software to write to the root directory.
printf 'run\tprivate/var/run\n' | sudo tee -a /etc/synthetic.conf
# If the following command fails, restart the OS to achieve the same thing.
/System/Library/Filesystems/apfs.fs/Contents/Resources/apfs.util -t

./result/sw/bin/darwin-rebuild switch --flake .

If the macOS user was not created by nix-darwin and Can't set user shell without giving nix-darwin complete control over my user issue is still not solved, run:

chsh -s /run/current-system/sw/bin/zsh

If infocmp alacritty produces an error, run:

ln -s ~/.nix-profile/share/terminfo/61/alacritty ~/.terminfo/61/alacritty
ln -s ~/.nix-profile/share/terminfo/61/alacritty-direct ~/.terminfo/61/alacritty-direct

If infocmp tmux-256color produces an error, run:

ln -s ~/.nix-profile/share/terminfo/74/tmux-256color ~/.terminfo/74/tmux-256color

From now on, changes to the configuration can be applied by running:

make switch

To activate configuration changes such as autohiding the dock, log out and log in again.

NixOS VM

Download the minimal NixOS ISO image.

Create a VMware Fusion VM with the following settings:

• Display: 3D graphics acceleration, maximum shared graphics memory, and full resolution for Retina display.
• Hard Disk: SATA 192 GB.

Once the VM is booted, change the root password to "root":

sudo su
passwd

Run ifconfig in the VM to figure out its IP address and export an environment variable with the VM's IP address:

export VM_ADDRESS=<VM's IP address>

Perform NixOS installation:

make vm-install

Then run:

make vm-bootstrap

Finally, reboot the VM by using the reboot command. After that, clone this repository inside the VM and use make switch from now on.
