Installing Homebrew

Homebrew cites itself as the missing package manager for MacOS. This is a third party application to ease in the installation of software on your MacOS system.

Open your terminal and run the following:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Once this has been completed, the install will suggest a few extra steps. These are very important and we repeat them here to be sure:

echo 'eval "$(`which brew` shellenv)"' >> ~/.zshrc

source .zshrc

You can confirm brew is installed correctly by running it's doctor command:

brew doctor

Installing additional tools

We'll install some basic tools to help during the course:

brew install tree

Installing oh-my-zsh

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
