Terminal is the default command line interface on macOS that allows users to interact with their system using text commands. It provides access to the Unix underpinnings of macOS, enabling advanced users to perform tasks that may not be possible through the graphical user interface. Terminal can be found in the Utilities folder within the Applications directory.

With Terminal, you can execute a wide range of commands to manage files, run scripts, configure system settings, and troubleshoot issues. This powerful tool is essential for developers, system administrators, and power users who need precise control over their Mac’s operations. Understanding basic Terminal commands can greatly enhance your ability to customise and optimise your macOS experience.
