Setting up a mac from scratch, how I do it.

System Settings

Open System Preferences.

Keyboard Settings

  • Key Repeat: Fastest
  • Delay Until Repeat: Shortest

Check “Use F1, F2, etc. keys as standard function keys” Click “Modifier Keys”, remap Caps Lock to escape on all keyboards.

Setting the Hostname

Open Sharing, set the hostname for the system there.


Open Sound, go to the Sound Effects tab, make sure “Play feedback when volume is changed” is checked.

Apps and Other Utilities

Go to the App Store, install xcode. Go wait for it to install.

Open Safari, go to, and follow it’s instructions to install homebrew.

Once that’s done, run the following commands:

brew cask install iterm2 shiftit alfred flycut macdown
brew install rbenv node tig the_silver_searcher jq wget tree

# Set up rbenv
rbenv init 2>&1 | tail -1 >> ~/.zshrc

# Get the latest ruby.
LATEST_RUBY=$(rbenv install -l | sed -n '/^[[:space:]]*[0-9]\{1,\}\.[0-9]\{1,\}\.[0-9]\{1,\}[[:space:]]*$/ h;${g;p;}')
rbenv install ${LATEST_RUBY}
rbenv global ${LATEST_RUBY}
gem install bundler

# mdspell
npm i markdown-spellcheck -g # For spellchecking the knowledge repo.

These install iterm2 (terminal emulator), shiftit (keyboard-based window manager), alfred (quick launcher, amongst other responsibilities), flycut (pasteboard manager), macdown (markdown editor)

They also install and set up rbenv (ruby environment), node, tig (git tree viewer), ag (Very fast file searcher), jq (json processor), wget (url downloader), tree (recursive directory listing command)


This is an interactive script. Go to, and copy the command they give and run it.

Install mdbook-generate-summary with cargo install mdbook-generate-summary once you’re done.


Open Xcode, open Settings. (cmd+,) Go to the ‘Text Editing’ section.

  • UNder the “Show” section, make sure “Code folding ribbon” is checked.
  • Under the “While Editing” section, make sure both “Automatically trim trailing whitespace” and “Including whitespace-only lines” are checked.

Quick Snippets

adding desc, qit, etc. to xcode.

Clone the [Quick Snippets repository], run, then restart xcode.

git clone
cd QuickSnippets
cd -
