User interface

The user interface (UI) refers to the style and feel of how an operating system or software product feels and acts. It is what you see and do. In Mac OS X, the graphical user interface (GUI) is based on the Aqua theme, menu bar, and iOS-like features.
==Classic Mac OS==
Classic Mac OS used a fairly consistent graphical user interface (GUI) style, modestly updating its classic black & white interface in System 7 and then revising it with the Platinum appearance in Mac OS 8.
===Macintosh System 1.1===
Macintosh System 1.1 was a black and white style GUI User Interface. At that time it had no name. It had the menu bar at top, although it was not used very much. The apple logo was on the left.
