System 7

System 7 (codenamed "Big Bang" and sometimes retroactively called Mac OS 7) is a single-user graphical user interface-based operating system for Macintosh computers. It was introduced on May 13, 1991, by Apple Computer. It succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. Features added with the System 7 release included virtual memory, personal file sharing, QuickTime, QuickDraw 3D, and an improved user interface.

"System 7" is often used generically to refer to all 7.x versions. With the release of version 7.6 in 1997, Apple officially renamed the operating system "Mac OS", a name which had first appeared on System 7.5.1's boot screen. System 7 was developed for Macs that used the Motorola 680x0 line of processors, but was ported to the PowerPC after Apple adopted the new processor.

Development

The development of the Macintosh "Systems" up to System 6 followed a fairly smooth progression with the addition of new features and relatively small changes and upgrades over time. Major additions were fairly limited, notably adding Color QuickDraw and MultiFinder in System 6. Some perspective on the scope of the changes can be seen by examining the official system documentation, Inside Macintosh. This initially shipped in three volumes, adding another to describe the changes introduced with the Mac Plus, and another for the Mac II and Mac SE.

System 7 (album)

System 7 is the first studio album by the dance/ambient band System 7.

A somewhat different version was released in the United States as 777 by 777. (777 was also the title of System 7's second UK album.) The running order is different, there are two different mixes of two tracks, and it has two completely new tracks - "Depth Disco" and "Mia".

With several vocal tracks, this album has rather a different feel from later System 7 albums. Aniff Cousins appears on "Freedom Fighters" (with Zoë providing chorus vocals) and "Dog", and Olu Rowe on "Habibi", "Bon Humeur" and "Strange Quotations".
