<operating system> (Mac OS) Apple Computer, Inc.'s proprietary operating system for their Macintosh family of personal computers. The part of the operating system that simulates the desktop is called "Finder." The multitasking version of Finder was called "MultiFinder" until multitasking was integrated into the core of the OS with the introduction of System 7.0 in 1990. The Macintosh series provides a built-in graphics language, called "QuickDraw", which provides a standard for software developers. Mac OS 8, scheduled for delivery in July 1997, included new human-interface features, increased system stability and performance, a PowerPC processor-native Finder, tighter integration of Internet access through panel-based "assistants," Personal Web Sharing and the ability to run Java applets and programs through Mac OS Run Time for Java. Version 9.2 was the last version of the bespoke Mac OS. The next version, Mac OS X is quite different, being based on Unix. See also Macintosh file system, Macintosh user interface. (2007-03-15)

EROS (microkernel)

Extremely Reliable Operating System (EROS) is an operating system developed starting in 1991 at the University of Pennsylvania, and then Johns Hopkins University, and The EROS Group, LLC. Features include automatic data and process persistence, some preliminary real-time support, and capability-based security. EROS is purely a research operating system, and was never deployed in real world use. As of 2005, development stopped in favor of a successor system, CapROS.

Examples of use of Macintosh Operating System

1. Apple (www.apple.com), for instance, added a better noise–canceling microphone to its iSight camera, priced at $14'.''. The newest version of the Macintosh operating system also includes a more sophisticated video compression algorithm called H.264.

2. Apple‘s CEO Steve Jobs rebutted by calling the record industry ‘greedy’. In the computer space, where Apple is seeing its best sales in years, information–security firms have discovered a few new vulnerabilities in its Macintosh operating system.
