How to install and uninstall HomeBrew on your Mac
If you’re the kind of Macs user who spends a lot of time using Terminal and need to install other command line tools like cask, htop, or wget, at some point you’ll want to install the Homebrew package manager, which makes it easier to install them. Here’s how to install and how to uninstall Homebrew.
What is Homebrew?
Homebrew is an open-source package management system that simplifies the installation of ‘home-brewed’ software on macOS. That is, the large body of UNIX and open source software available for download. It’s written in Ruby and consists of a git repository, which allows updated repositories to be downloaded from GitHub.
Homebrew downloads the files necessary to install and run a piece of software and then compiles them into binaries for installation.
Why would I install Homebrew?
If you’re interested in installing UNIX tools that don’t come with their own installers for macOS, Homebrew makes finding, creating and configuring installation packages much easier than doing it manually.
How to install Homebrew
In addition to a Mac with Mac OS X or macOS installed and a little knowledge of using bash or zsh, you will need to install Command Line Tools before attempting to install Homebrew. Here’s how to do that.
- Go to Applications>Utilities and double-click Terminal to launch it.
- Type this command: `xcode-select —-install`
- You will see a pop-up window telling you that ‘xcode-select’ requires access to command line developer tools and asking for your permission got install them. Press Install.
- Wait for the installation to finish.
Once Command Line Tools has installed, you can go ahead and install Homebrew like this:
- Launch Terminal again.
- Type in the following command:
`/use/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”`
- Press Return and you’ll see a number of lines explaining telling you what the script will install and where it will install it.
- Hit Return again.
- Type in your admin password.
- When installation is complete – which could be a while, depending on your Mac and internet connection speed – you will see a message that says ‘installation successful’.
Once you see that message, you can start to install software packages using Homebrew. First, though, it might be worth reading the documentation. To do that, use this command in Terminal:
To install packages, use the following syntax:
`brew install [package name]`
So, to install cask, for example, the command would be:
`brew install cask`
How to uninstall Homebrew on your Mac
There are a number of ways to uninstall Homebrew on your Mac. One method is to use read the documentation and follow the instructions there to manually uninstall. Use this command:
Another method is to use a ruby curl command to download the uninstall script from GitHub and execute it. To do that, use this command:
`ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)”`
If you don’t want to use curl to execute a script downloaded from the internet, you can download it manually, review it, and then execute it. The script can be downloaded here: https://raw.githubusercontent.... Once you’ve downloaded it, save it as a text document and then run the uninstall using that.
