macOS command line tool installation guide: Easily get development tools

The Xcode command line tool is an optional component of Xcode that brings a variety of advanced utilities to the Mac command line, including compilers, debuggers, and other necessary tools for software development and command line operations. Even if you are not a developer, you may need to install command line tools on your Mac, as it is also a prerequisite for installing popular package managers and casings such as Homebrew.

Whether you have recently installed macOS Sequoia or Sonoma, installing the command line tool is very easy.

Installing command line tools in macOS is relatively simple, but if you are not familiar with this process, you may not know where to start, or it may seem daunting because it involves using a terminal. Don't worry, we'll walk you through these steps step by step in a simple way.
