Setting up MacOS for development - cheatsheet

Posted 01 Jan 2019

The following provides a quick guide to setting up a new Mac - primarily for the use a development machine. I use this for myself and new employees whenever needing to set up a new machine:

Homebrew and Cask

For most dependencies install Homebrew (please refer to the original site in the event the instructions are out of date):

/usr/bin/ruby -e "$(curl -fsSL"

For graphical applications, install Brew Cask:

brew tap caskroom/cask

Then install all your favourites, such as:

brew cask install google-chrome
brew cask install dropbox
brew cask install spotify
brew cask install postico
# etc

NVM, Node and Yarn

Install Node version manager:

curl -o- | bash

Ensure you follow the steps at the end of the install - namely add the following to ~/.bash_profile:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/" ] && \. "$NVM_DIR/"  # This loads nvm

Reopen your terminal window and install node:

nvm install 9
nvm alias default 9

Install Yarn via Brew:

brew install yarn --without-node

Ruby version manager:

Install the Ruby version manager:

\curl -sSL | bash -s stable

Install Ruby:

rvm install ruby
gem install bundler

Setting up your GitHub SSH key:

Connecting to GitHub

ssh-keygen -t rsa -b 4096 -C "YOUR_EMAIL"
pbcopy < ~/.ssh/
