Command Line Tools are an optional component of Xcode that bring a variety of advanced utilities to the Mac command line, including compilers, debuggers, and other essentials for software development and command line tinkering.
Installing Command Line Tools in MacOS is relatively simple, Open the Terminal application and enter the command 'xcode-select --install' to start the installation process.
Once installed, Command Line Tools can be used immediately, or you can proceed with your desired tasks such as installing Homebrew.
If the installation via command line fails, you can manually download and install Command Line Tools through the developer.apple.com website.
