Installing Homebrew on a Mac

  Technology, Misc Tools, Systems

Advanced Mac users may appreciate using the Homebrew package manager, which greatly simplifies the process of installing command line software and tools on a Mac.

For example, if you want to easily install favorite command line tools on a Mac like cask, htop, wget, nmap, tree, irssi, links, colordiff, or virtually any other familiar unix command line utility, you can do so with a simple command. Homebrew downloads and builds the package for you.

This is obviously aimed at more technically savvy Mac users who spend a lot of time at the command line. While there’s no particular issue for novice users installing Homebrew on their Mac, the odds of novices finding it useful are slim, unless they intend to embark on learning the command line environment. Contrast that to power users who practically live in a terminal environment, whether longtime Mac users or migrating to the platform from the Windows or Linux world, who will immediately see the value of Homebrew.

Requirements for Installing Homebrew on Mac OS

prerequisites to installing Homebrew on a Mac include the following:

  • A Mac running Mac OS X 10.10 or later, though earlier versions are sort of supported
  • Command Line Tools must be installed on the Mac (either independently or through Xcode)
  • Knowledge of the command line and using bash or zsh

Assuming you’re interested in installing Homebrew and meet those requirements, then the rest is equally straight forward.

How to Install Homebrew on Mac OS

The simplest way to install Homebrew is through ruby and curl, accomplished with a single command. This approach is the same for installing Homebrew in all supported versions of Mac OS and Mac OS X.

    1. Open the “Terminal” application, found in /Applications/Utilities/
    2. Enter the following command into a single line of the terminal:

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

  1. Hit Return and you’ll see a series of lines about what the script will install and where, hit Return again to agree or hit Escape to cancel
  2. Enter the administrator password (required by sudo execution) to begin installation

Installation of Homebrew will take a while depending on the speed of your Mac and internet connection, as each necessary package is downloaded and installed by the script.

When complete, you will see an “Installation successful!” message.

 

Now you’re ready to install software packages through Homebrew, or you can read the help documentation with the following command:

brew help
