Homebrew Package Manager

Homebrew is a free and open-source software package management system that simplifies the installation, updating, and management of software on Apple's macOS, as well as on Linux and the Windows Subsystem for Linux (WSL). Often referred to as "The missing package manager for macOS," it allows users to easily install command-line tools, applications, and libraries using simple terminal commands. Homebrew automatically handles dependencies, ensuring that all required components for a piece of software are also installed, making it an indispensable tool for developers and power users who need to manage a wide array of software not available through standard application stores.
