What Does Mac Terminal Mean?
The Mac Terminal is a command line interface (CLI) for Mac OS X available in all OS X versions through Lion. It is also a gateway to Unix, or the underlying operating system of OS X. Terminal allows users to modify various characteristics of their Mac desktops, fonts, files and more beyond the standard OS X graphical user interface (GUI). It allows for total customization and command. However, if novice computer users apply modifications incorrectly, this can harm the system or lead to a loss of data.
Located in the Mac Utilities folder, Terminal has a black icon with a gray border.
