Mac OS System 7, is a graphical user interface-based operating system for Macintosh computers and is part of the classic Mac OS series of operating systems. It was introduced on May 13, 1991, and succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. It included virtual memory, personal file sharing, QuickTime, QuickDraw 3D, and an improved user interface.

Codenamed "Big Bang", and also known as Mac OS 7,

Apple officially renamed the operating system "Mac OS", a name which had first appeared on System 7.5.1's boot screen on the release of version 7.6 in 1997. It was developed for Macs that used the Motorola 680x0 line of processors, but was ported to the PowerPC after Apple adopted the new processor in 1994 with the introduction of the Power Macintosh.

Mac OS System 7.5, included bug fixes and included: An updated startup screen featuring a progress bar; A new interactive help system Apple Guide; a clock in the menu bar; an Apple menu item called Stickies; WindowShade to condense a window down to its title bar; MacTCP was bundled, enabling connect to the Internet; Control Strip previously only included with the PowerBook; A new Desktop Patterns control panel for 128x128 pixels with 8-bit color; the Extensions Manager; PowerTalk, a system-level email handling service and the originator of the Keychain system; Launcher, a control panel containing shortcut buttons for frequently used programs; a hierarchical Apple menu; System-wide drag & drop for text and other data;a scriptable Finder; QuickDraw GX, a 2-D graphics engine; for the PowerPC only, an advanced, 3d Graphing Calculator; support for OpenDoc

System 7.5 was codenamed "Capone", a reference to Al Capone and "Chicago", which was the code name for Microsoft's Windows 95, and was also the name of the default system font used in Mac OS until version 8.
