This memory system enabled more applications to run simultaneously, tremendously reducing the possibly of programs crashing each other. This system was built on the Mach kernel and BSD implementation of Unix, features originally incorporated in the NeXTSTEP operating system. Mac OS X introduced a Unix-like memory management system and preemptive multitasking to the Macintosh platform. Mac operating systems are currently compatible with PowerPC and Intel hardware. Shortly thereafter, Apple released computers with PowerPC hardware, eventually updating their operating system to support the new architecture. Mac OS X was officially released in 1997, with early versions only supporting Motorola 68000-based Macintosh computers. According to CEO Steve Jobs, Apple purposely downplayed the existence of their operating system to distance it from systems like MS-DOS, which was viewed as more technically challenging. The first version was very integral to the original Macintosh in 1984, yet unnamed and simply referred to as system software. Mac OS is the flagship series of GUI (Graphical User Interface) based operating systems designed for Apple's Macintosh computer. Home › Operating Systems › Mac The Mac Operating System
