macOS dotfiles

This repo is a little quirky at the moment; I'm half way between a Nix-style setup and a stow-based one. Eventually this will be fully Nix-based but for now we do some non-reproducible stuff with bootstrap.

Prerequisites

1. git
2. nix
3. Nix experimental features enabled:

echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf

Installation Instructions

nix profile add github:collinmurch/dotfiles#pkg-set

# expect stow conflicts on first run
nix run github:collinmurch/dotfiles#bootstrap 

Additional Optional Config

Custom Environments

Shared environment variables (~/.env)

Both env.nu and .zshenv load ~/.env on startup if it exists. Use standard KEY=VALUE (dotenv) format with double-quoted values. This file is gitignored so it stays local to each machine.

EXAMPLE_VARIABLE="some-value"
ANOTHER_VARIABLE="another-value"

Shell-specific overrides

If either of these files are present, they will be sourced by the respective shell:

• Zsh: ~/.zprofile
• Nushell: $nu.default-config-dir/local.nu (overlay)

Additional sandbox permissions for Codex and Claude Code:

• Codex:
  • ~/.codex/rules/*.rules (any name but base.rules)
  • ~/.codex/config.toml (config.base.toml is merged in at initialization)
• Claude Code: ~/.claude/settings.json (~/.claude/settings.base.json is merged in at initialization)

Fonts

This setup includes encrypted TX-02 (Berkely Mono) fonts that are optionally decrypted during bootstrap.sh using my Bitwarden SSH key. JetBrains Mono is installed and is a fallback font for all configs if TX-02 isn't found.

MacOS System Settings

A list of defaults & functionality explanations I prefer can be set with /bin/zsh config_macos.sh, which I wouldn't recommend just running. I'll probably migrate this to nix-darwin at some point.

Raycast

1. Export settings under Advanced from previous machine
2. Import them under the same tab on a new machine
3. Check to make sure scripts are loaded from ~/Developer/scripts
