# Homebrew: macOS Package Manager for Python



Homebrew is a package manager for macOS and Linux that makes installing software packages simple. While not Python-specific, it provides an important way to install Python tools and dependencies on macOS systems.

## Core Capabilities

- Installs packages ("formulae") and larger binary packages ("casks")
- Manages package dependencies
- Updates installed packages
- Installation and uninstallation using `brew install` and `brew uninstall`
- Installs [Python interpreters](https://pydevtools.com/handbook/explanation/what-is-a-python-interpreter.md) (`brew install python`)
- Installs Python tools like [uv](https://pydevtools.com/handbook/reference/uv.md) and [pipx](https://pydevtools.com/handbook/reference/pipx.md)
- Provides dependency libraries needed for Python packages (e.g. openssl, sqlite)

{{< callout type="warning" >}}
While Homebrew can install Python, it's not recommended as your primary way to manage Python versions for development projects. Homebrew updates can unexpectedly change Python versions, breaking your project environments. Instead, use dedicated Python version management tools like [`uv python install`](https://pydevtools.com/handbook/how-to/how-to-install-python-with-uv.md) or [pyenv](https://pydevtools.com/handbook/reference/pyenv.md) which provide more reliable and granular control over Python versions. See [Should I use Homebrew to install Python?](https://pydevtools.com/handbook/explanation/should-i-use-homebrew-to-install-python.md) for the full reasoning.
