:boot: Bootstrap your OS X development system.

3 years after MIT


Strap is a script to bootstrap a minimal OS X development system. This does not assume you're doing Ruby/Rails/web development but installs the minimal set of software every OS X developer will want.


  • Disables Java in Safari (for better security)
  • Enables the OS X screensaver password immediately (for better security)
  • Enables the OS X application firewall (for better security)
  • Adds a Found this computer? message to the login screen (for machine recovery)
  • Enables full-disk encryption and saves the FileVault Recovery Key to the Desktop (for better security)
  • Installs the Xcode Command Line Tools (for compilers and Unix tools)
  • Agree to the Xcode license (for using compilers without prompts)
  • Installs Homebrew (for installing command-line software)
  • Installs Homebrew Versions (for installing older versions of command-line software)
  • Installs Homebrew Bundle (for bundler-like Brewfile support)
  • Installs Homebrew Services (for managing Homebrew-installed services)
  • Installs Homebrew Cask (for installing graphical software)
  • Installs the latest OS X software updates (for better security)
  • Installs dotfiles from a user's repository and runs script/setup to configure them.
  • Installs software from a user's Brewfile in their repository or .Brewfile in their home directory.
  • A simple web application to set Git's name, email and GitHub token (needs to be authorized on any organizations you wish to access)
  • Mostly idempotent (the slow bit is rerunning brew update)
