The instructions below assume that you are using a Mac with "Homebrew" installed. Homebrew is a package manager for MacOS that makes it easy to install software. If you're familiar with Linux "apt-get" or "yum" commands, the "brew" command works similarly. For more information on installing Homebrew, visit their website at https://brew.sh/. To quickly install Homebrew, follow these steps as a non-root user in a terminal window.
