Macintosh computer

A popular model of computer made by Apple Computer. Introduced in 1984, the Macintosh features a graphical user interface (GUI) that utilizes windows, icons, and a mouse to make it relatively easy for novices to use the computer productively. Rather than learning a complex set of commands, you need only point to a selection on a menu and click a mouse button.Moreover, the GUI is embedded into the operating system. This means that all applications that run on a Macintosh computer have a similar user interface. Once a user has become familiar with one application, he or she can learn new applications relatively easily. The success of the Macintosh GUI led heralded a new age of graphics-based applications and operating systems. The Windows interface copies many features from the Mac.There are many different Macintosh models, with varying degrees of speed and power. All models are available in many different configurations. All models since 1994 are based on the PowerPC microprocessor.
