If you've ever used Terminal on a Mac, you have probably heard about Homebrew. Installing Homebrew on a Mac is quite simple, and it extends the Mac operating system while also giving Terminal wings to fly.
How to Install Homebrew
Homebrew relies on some support from Apple's Xcode. Therefore, you need to install that, too. Follow the steps below to get started:
Open Terminal from the Applications folder or Launchpad.
Copy and paste the following command into Terminal, then press Return./usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
As part of the install, Homebrew will also install Apple's Xcode developer software. A pop-up will prompt you to approve this.
Press the Return key to continue.
Enter your administrator password, then press Return again.
The Homebrew installation will begin. It may take a few seconds to install completely.
At the end of the text on the Terminal window, you will see the words Installation successful.
You will also see information about Homebrew analytics and a link if you want to learn more. You can opt-out of analytics gathering if you want for privacy purposes.
Close the Terminal window.
What Is Homebrew?
Homebrew is the most popular Mac package manager. Packages are bundles of source code created by developers. Some of the files may be programs, support code, and other bits and pieces needed for the software to run. Homebrew installs open-source, command-line tools, and applications like Google Chrome and VLC effortlessly with a single command. You don't have to worry about unzipping files or installing pieces of software in any order. Homebrew does it all for you.
Most Mac users are familiar with dragging a DMG file to the Applications folder to install the software. Sometimes, these installs fail because you needed to take additional steps beforehand. With Homebrew, all the prerequisites are handled automatically in the correct order.
How to Use Homebrew
To use Homebrew, open Terminal, enter the command using lower-case letters, then press Return to execute it. Be aware of spaces and hyphens.
Try running brew doctor to check to see that everything is installed okay and make sure there aren't any updates you need to apply. Run brew help to see a list of common commands.
