History: System 7 was a version of Mac OS, the operating system of the Apple Macintosh computer, which was used in the early 1990s up until 1997, as the successor to System 6. It featured built-in cooperative multitasking, virtual memory, personal file sharing, a slightly 3D looking interface taking advantage of colors, QuickTime for video capture and playback, and QuickDraw 3D for 3D graphics. It is still widely used by many Macintosh users who own Apple hardware of similar vintage. The "System 7" term is used to describe all the 7.x versions. The codename used for System 7 was "Big Bang", which reflects the considerable changes that came with it. System 7.0 was released on May 13, 1991. It offered a number of system enhancements that were either previously not available, or were optional extensions to the operating system.
