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 for development. Also trigger when someone mentions setting up Homebrew, Oh-My-ZSH, Node.js, Python, Docker, or terminal configuration on a new Mac — even if they don't call it a "setup". This skill is opinionated and based on real-world experience setting up M-series Macs for fullstack JS/TS + Python + AI development.
