• The Mac Terminal is a command-line interface for easily controlling and changing your operating system.
• It's simple to find the Terminal app in the Finder or Spotlight on your Mac.
• You can use it to open a programme, a file (through the default app), a file using a specified application, or a file using the text editor.
• If you're unfamiliar with the Mac Terminal, think of it as the ultimate command shortcut hub, allowing you to quickly and efficiently take command of your operating system (it's also something you might use if you're familiar with UNIX operating systems).
