Installing Homebrew on macOS

Homebrew is the most popular package manager on macOS, and it is easy to use and very versatile. Installing Homebrew on macOS is simple; just follow the instructions at https://brew.sh/:

1. In a nutshell, open a new Terminal window and execute the following command to install Homebrew:

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Once the installation is finished, test whether Homebrew is working by entering brew --version in the Terminal. You should see something like this:

$ brew --version
Homebrew 2.1.4
Homebrew/homebrew-core (git revision 77d1b; last commit 2019-06-07)

3. Now, we are ready to use Homebrew to install tools and utilities. If we, for example, want to install the Vi text editor, we can do so like this:

$ brew install vim

This will then download and install the editor for you.
