Installation

The suggested and easiest way to install Homebrew is on the homepage.

The standard script installs Homebrew to /usr/local so that you don’t need sudo when you brew install. It is a careful script; it can be run even if you have stuff installed to /usr/local already. It tells you exactly what it will do before it does it too. And you have to confirm everything it will do before it starts.

Requirements

Alternative Installs

OS X Mountain Lion (10.8) and below

Because GitHub now only allows clients that support TLS 1.2 to access repositories over HTTPS, the Homebrew installer will use the Git protocol when run on systems older than OS X Mavericks (10.9). This requires the availability of a git binary, which can be provided by pre-installing the Command Line Tools for Xcode. Homebrew will also require the Command Line Tools or Xcode in order to automatically compile and install a newer curl and git with support for TLS 1.2.

Untar anywhere

Just extract (or git clone) Homebrew wherever you want. Just avoid:

However do yourself a favour and install to /usr/local. Some things may not build when installed elsewhere. One of the reasons Homebrew just works relative to the competition is because we recommend installing to /usr/local. Pick another prefix at your peril!

mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

Multiple installations

Create a Homebrew installation wherever you extract the tarball. Whichever brew command is called is where the packages will be installed. You can use this as you see fit, e.g. a system set of libs in /usr/local and tweaked formulae for development in ~/homebrew.

Uninstallation

Uninstallation is documented in the FAQ.

1 For 32-bit or PPC support see Tigerbrew.

2 10.12 or higher is recommended. 10.9–10.11 are supported on a best-effort basis. For 10.4-10.6 see Tigerbrew.

3 Most formulae require a compiler. A handful require a full Xcode installation. You can install Xcode, the CLT, or both; Homebrew supports all three configurations. Downloading Xcode may require an Apple Developer account on older versions of Mac OS X. Sign up for free here.

4 The one-liner installation method found on brew.sh requires a Bourne-compatible shell (e.g. bash or zsh). Notably, fish, tcsh and csh will not work.
