Homebrew is a non-profit project run entirely by volunteers, not employees. We need your funds to pay for software, hardware and hosting around continuous integration and future improvements to the project. Every donation will be spent on making Homebrew better for our users.

Please consider a regular donation through GitHub Sponsors, Open Collective or Patreon. Homebrew is fiscally hosted by the Open Source Collective.

Read the Homebrew manual with man brew.

Read installation, troubleshooting, contribution including the FAQ on docs.brew.sh.

Read the Homebrew Blog for release notes, project updates and announcements.

Find formulae, casks, dependencies, versions and package metadata on formulae.brew.sh.

View anonymised install, build and operating system usage data at formulae.brew.sh/analytics. Read how Homebrew uses Anonymous Analytics.

First, please run brew update and run (and read) brew doctor.

Second, read the Troubleshooting Checklist.

If you don't read these it will take us far longer to help you with your problem.

After this, if you still need help, please ask in Homebrew/discussions or follow (and read) the Homebrew/brew new issue chooser.

Follow Homebrew on Mastodon, Bluesky, 𝕏 (Twitter) or subscribe to the newsletter.

We'd love you to join us and >10,000 others by contributing to Homebrew!

First, please read our Contribution Guide and Code of Conduct.

A good starting point for contributing is:

• brew tap --force homebrew/core or brew tap --force homebrew/cask (depending on whether you'd rather work on formulae or casks)
• perform a strict audit on a package you use e.g. brew audit --strict ffmpeg for FFmpeg
• if no warnings, run brew audit --strict to run on all packages and pick one to fix
• read through the warnings and fix them until brew audit --strict <package> shows no results
• submit a pull request with your fixes

Alternatively, for something more substantial, check out one of the open issues in Homebrew/brew, Homebrew/homebrew-core or Homebrew/homebrew-cask.

If you've had inspiration for a new feature or bug fix: we don't need you to open an issue first, just open a pull request with your implementation and we'll review it.

Good luck!

Please see our security policy for how to report security issues and what is in scope.
