Fully automated new Mac setup for fullstack web developers and AI engineers. Generates and executes idempotent shell scripts to install dev tools, CLI utilities, GUI apps, AI/ML tooling, shell config, and macOS preferences — all via Homebrew, fnm, uv, and defaults commands. Use this skill whenever someone says "set up my Mac", "new Mac setup", "configure my dev machine", "install my dev tools", "fresh Mac install", "developer environment setup", or anything about bootstrapping a macOS machine…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# New Mac Setup This skill generates and runs a complete, idempotent Mac setup for fullstack web development and AI engineering. It produces 8 shell scripts that can be run individually or via a master runner, plus dotfiles and macOS preference automation. The scripts are designed to be re-runnable — they check whether each tool is already installed before attempting installation, so you can safely run them again if something fails partway through. ## Philosophy The setup is opinionated. The core opinions: - **Terminal**: Ghostty (fast, GPU-accelerated, Zig) + cmux (vertical tabs, split panes, socket API for AI agents). cmux reads Ghostty's config, so one config file serves both. - **Shell**: ZSH with Oh-My-ZSH, powerlevel10k theme, zsh-autosuggestions, zsh-syntax-highlighting - **Node**: fnm (not nvm — fnm is faster), pnpm and bun for package management/runtime - **Python**: uv from Astral (not pyenv, not pip, not conda — uv is dramatically faster and handles both venvs and package installs) - **Docker**: Colima (not Docker Desktop — lighter weight, CLI-native, free) - **Editor**: Cursor (AI-native editor) …

How to install
mdr add swyxio/skills/new-mac-setup@sha256:5a6dba717e50330fThe line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
