"System 7" is often used generically to refer to all 7.x versions. On January 24, 1984, Apple Computer Inc (now Apple Inc) introduced the Apple Macintosh Personal computer, with the Macintosh 128K 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 the Motorola 68k processor, but was ported to the PowerPC after Apple adopted the new processor. The Motorola 680x0 / m68k / 68k / 68K is a family of 32-bit CISC Microprocessor CPU chips and was the primary PowerPC is a RISC Instruction set architecture created by the 1991 Apple – IBM – Motorola alliance known as AIM
Compared with System 6, System 7 offered:
System 7 was the first version of the Mac OS that required a hard drive as it was too large to work comfortably from floppy disk. A floppy disk is an increasingly Obsolete data storage medium that is composed of a disk of thin flexible ("floppy" Magnetic storage medium encased It was also the first Apple operating system to be available on CD. System 7 itself did not come bundled with major software packages, however newly purchased Macintosh computers were often bundled with software such as HyperCard, ClarisWorks, Power Pete, Mac-Chess, and Netscape. Macintosh, commonly nicknamed Mac is a Brand name which covers several lines of Personal computers designed developed and marketed by Apple Inc HyperCard was an Application program created by Bill Atkinson for Apple Computer Inc AppleWorks refers to two different Office suite products both of which are now discontinued Power Pete is a computer game developed by Pangea Software and published by the Interplay Entertainment Corporation under the MacPlay brand name Netscape Communications (formerly known as Netscape Communications Corporation and commonly known as Netscape) is an American computer services company PowerPC Macintoshes included Graphing Calculator. PowerPC is a RISC Instruction set architecture created by the 1991 Apple – IBM – Motorola alliance known as AIM NuCalc, also known as Graphing Calculator, is the name of a Computer software tool made by the company Pacific Tech capable of performing many graphing calculator System 7 also included networking and file sharing software in the form of system extensions and control panels.
The basic utilities installed by default with System 7 included TeachText (superseded by the more flexible SimpleText in later versions) for basic text editing tasks and reading readme documents. The TeachText application is a simple Text editor made by Apple Computer bundled with System 7 SimpleText is the native Text editor for the Classic Mac OS. SimpleText allows editing including text formatting (underline italic bold etc fonts and sizes A readme (or read me) file contains information about other files in a directory or archive and is very commonly distributed with computer Also available on the additional "Disk Tools" floppy disk are Disk First Aid for disk repair and Apple HD SC Setup for initializing and partitioning disks.

Later versions of System 7, specifically System 7. 5 and Mac OS 7. 6, came with a dedicated "Utilities" folder and "Apple Extras" folder including: AppleScript, Disk Copy, QuickDraw GX Extras and QuickTime Movie Player. AppleScript is a Scripting language devised by Apple Inc, and built into Mac OS. Disk Copy was the default utility for handling Disk images in System 7 through Mac OS X 10 QuickDraw GX was a replacement for the QuickDraw (QD 2D graphics engine and Printing Manager inside the "classic" Mac OS. QuickTime is a Multimedia framework developed by Apple Inc, capable of handling various formats of Digital video, Media clips sound text More optional extras and utilities could be manually installed from the System CD.
System 7. 1. 2 was the first version of the Mac OS to support Apple's new PowerPC-based computers. PowerPC is a RISC Instruction set architecture created by the 1991 Apple – IBM – Motorola alliance known as AIM 68k applications which had not yet been updated to run natively on these systems were emulated transparently (without users' knowledge) by a built-in 68k processor emulator. An emulator duplicates (provides an emulation of the functions of one System using a different system so that the second system behaves like (and appears to The Mac 68K emulator was a Software Emulator built into all versions of the Mac OS for PowerPC. Fat binaries, which contained the code necessary to run natively on both PowerPC and 68k systems, became common during this time.

A universal binary is in Apple parlance an Executable file or application bundle that runs natively on PowerPC is a RISC Instruction set architecture created by the 1991 Apple – IBM – Motorola alliance known as AIM
System 7. 0 through 7. 1 offered a utility called Apple File Exchange, which could access the contents of FAT- and Apple II-formatted floppy disks. Apple File Exchange is a Utility included on the Tidbits disk or Install 2 disk in system versions 7 Templateinfobox filesystem whilst covering all 3 file systems please make any style changes to both at the same time System 7 Pro, System 7. 5 and up shipped with PC Exchange, previously a separate product, which allowed the system to mount FAT-formatted floppy disks on the desktop in the same manner as regular Macintosh disks. PC Exchange was a Mac OS control panel that lets the Operating system mount FAT File systems and mapped file extensions A floppy disk is an increasingly Obsolete data storage medium that is composed of a disk of thin flexible ("floppy" Magnetic storage medium encased System 7 also can read HPFS and NTFS formatted drives.

System 7 allowed users to access PC networks and allowed communication. Third party software such as SoftPC allowed compatibility between MS-DOS and Microsoft Windows programs while others such a Connectix Virtual PC allowed the Mac to run Windows and the Mac OS to run via emulation. Others took a more native approach by running Windows and MS-DOS by using x86 expansion cards with an x86 chip on the card. Microsoft released versions of Internet Explorer 2 and 2. Microsoft Internet Explorer 2 (Internet Explorer 20 is a graphical Web browser released in November 1995 by Microsoft for Windows 95 and 1, Internet Explorer 3, and Internet Explorer 4 for PPC and 68k Macs. Microsoft Internet Explorer 3 (Internet Explorer 30 is a graphical Web browser released on August 13 1996 by Microsoft for Microsoft Windows and Microsoft Internet Explorer 4 (also IE4) is a graphical web browser released in September 1997 by Microsoft, primarily for Microsoft Windows, but also IE 4. 5 for Mac dropped 68k support, and Internet Explorer 5 only supported PPC, although development ended with the last patch version being Version 5. Microsoft Internet Explorer 5 (abbreviated IE5) is a graphical Web browser released in March 1999 by Microsoft, primarily for Microsoft Windows 1. 7 released in July 2003.
At the time of its release, many users noticed that performance suffered as a result of upgrading from System 6 to System 7, though newer hardware soon made up for the speed differential. System 6 (also referred to as System Software 6) is a Graphical user interface -based Operating system for Macintosh computers Another problem was System 7's large "memory footprint": System 6 could boot the system from a single floppy disk and took up about 600 KB of RAM, whereas System 7 used well over a megabyte, and could no longer be usefully run from floppy-only machines without the aid of an external SCSI hard drive. A floppy disk is an increasingly Obsolete data storage medium that is composed of a disk of thin flexible ("floppy" Magnetic storage medium encased A kilobyte (derived from the SI prefix Kilo -, meaning 1000 is a unit of Information or Computer storage equal to either 1024 A megabyte is a unit of Information or Computer storage equal to either 106 (1000000 Bytes or 220 (1048576 bytes depending on A hard disk drive ( HDD) commonly referred to as a hard drive, hard disk, or fixed disk drive, is a Non-volatile storage device (Versions up to 7. 5 could boot from a floppy, but there would be no room for other applications, although it was possible to access an AFP server on an AppleTalk network. The Apple Filing Protocol ( AFP) is a layer 6 ( Presentation layer) network protocol that offers file services for Mac OS X and original Mac ) It was some time before the average Mac shipped with enough RAM built in for System 7 to be truly comfortable. Offsetting this was the inclusion of a hard disk as standard in most Mac models; only the long-lived Mac Plus and certain models of the Macintosh SE did not ship with one. The Macintosh Plus computer was the third model in the Macintosh line introduced two years after the original Macintosh and a little more than a year after the Macintosh The Macintosh SE was a Personal computer manufactured by Apple between March 1987 and October 1990
System 7. 0 was adopted quite rapidly by Mac users, and quickly became one of the base requirements for new software.
The engineering group within Apple responsible for System 7 came to be known as the "Blue Meanies", named after the blue index cards on which were written the features that could be implemented in a relatively short time. The Blue Meanies of Apple Computer was an engineering group primarily responsible for the architecture of System 7 during the early 1990s An index card is heavy Paper stock cut to a standard size Index cards are often used for recording individual items of information that can then be easily rearranged and filed In comparison, the pink index card features were handled by the Pink group, later becoming the ill-fated Taligent project. Taligent ( Tal ent and Intell' igent') was the name of an object-oriented Operating system and the company dedicated to producing it
System 7. 0 was the last version of the Macintosh operating system to be made freely available and redistributable by Apple. Although it could be purchased from Apple, the cost was nominal and considered to only cover duplication and media. It was perfectly legal to copy a friend's System 7 installation floppies, and it was common for Macintosh dealers to allow customers to use the store's demo machines to copy System 7 install disks for the cost of a box of floppies. Many CD-ROM magazines such as Nautilus included System 7 on their disks. Nautilus (from Greek ναυτίλος, 'sailor' is the common name of any marine creatures of the Cephalopod family Nautilidae, the sole Apple started selling the Mac OS as a retail product with System 7. 1. System 7. 5. 3r2 is also freely downloadable from Apple's web site – seemingly in contravention to Apple's retail policies – but this release is free as a mea culpa for the extremely botched initial releases of Open Transport and System 7. 5. 2.

A patch called "System 7 Tune-Up" also followed, which fixed the "disappearing files" bug in which the system would lose files.  In August 1992, the 7. 1 update was released which introduced the Fonts folder, allowing users to organize their fonts in the Finder, replacing the Font/DA Mover application used in System 6. In the operating system for the Apple Macintosh computer a Desk Accessory (DA was a piece of Software, originally written as a device driver conforming
The first major upgrade was System 7. 1. 1, also known as "System 7 Pro". This release was a bundle of 7. 1 with AppleScript tools, QuickTime and Apple Open Collaboration Environment (AOCE). QuickTime is a Multimedia framework developed by Apple Inc, capable of handling various formats of Digital video, Media clips sound text Apple Open Collaboration Environment, or AOCE (sometimes OCE) was a collection of messaging-related technologies introduced for the Mac OS in the early While System 7 had some trouble running in slightly older machines due to memory footprint, System 7 Pro barely fit into any Macintosh computers at the time. It was most commonly used for its minor bug fixes rather than its new functionality.
Apple joined the AIM alliance (Apple, IBM and Motorola) shortly after the release of System 7 in 1991, and started work on PowerPC-based machines that later became the Power Macintosh family. The AIM alliance was an alliance formed in September 1991 between Apple Computer, IBM and Motorola to create a new computing standard based PowerPC is a RISC Instruction set architecture created by the 1991 Apple – IBM – Motorola alliance known as AIM Power Macintosh, later Power Mac, is a line of Apple Macintosh Workstation -class Personal computers based on various models of PowerPC Support for these machines resulted in System 7. 1. 2.
System 7. 1. 2 was never offered for retail sale; it shipped with the first batches of the PowerPC Macs. Later shipments shipped with System 7. 5 instead.
The next major release was System 7. 5 (codenamed "Capone", a reference to Al Capone and to ‘Chicago’, the code name for Microsoft's Windows 95), which included bug fixes from previous updates and added several new features including:
System 7. QuickDraw GX was a replacement for the QuickDraw (QD 2D graphics engine and Printing Manager inside the "classic" Mac OS. A graphing calculator (also known as a graphic calculator or graphical calculator) typically refers to a class of handheld Calculators that are capable of OpenDoc was a multi-platform Software componentry framework standard for Compound documents inspired by the Xerox Star system and intended as an alternative 5. 1 was primarily a bug fix on 7. 5, but also introduced a new "Mac OS" startup screen in preparation for Mac clones. A Macintosh clone is a personal computer made by a manufacturer other than Apple, using (or compatible with Macintosh ROMs and System software
System 7. 5. 2, released only for the first PCI-based Power Macs, was notable for introducing Apple's new networking architecture, Open Transport and also for being the most unstable version of Mac OS in recent memory. The Peripheral Component Interconnect, or PCI Standard (commonly PCI) specifies a Computer bus for attaching peripheral devices to a Computer Open Transport was the name given by Apple Computer to their implementation of the Unix -originated System V STREAMS, replacing MacTCP
System 7. 5. 3, a major bug-fix update that also included Open Transport for other PowerPC-based machines as well as some 68k-based machines. Open Transport was the name given by Apple Computer to their implementation of the Unix -originated System V STREAMS, replacing MacTCP 7. 5. 3 also made several improvements to the 68k emulator, and added translucent dragging support to the Drag Manager. It was also the first version of Control Strip for all Macs. The Control Strip is a component of System 7 and remained until the cancellation of the classic Mac OS in December 2001 This was also the first version of Mac OS to support SMP. In Computing, symmetric multiprocessing or SMP involves a Multiprocessor computer-architecture where two or more identical processors can connect to a single (9500/MP) a System 7. 5. 4 was pulled due to a mistake at Apple, where some components were not included in the installer, and replaced with System 7. 5. 5.
In addition to this, Open Transport was updated separately twice. Open Transport was the name given by Apple Computer to their implementation of the Unix -originated System V STREAMS, replacing MacTCP
Mac OS 7. 6 (codenamed "Harmony") was the last major update, released in 1997. With 7. 6, the operating system was officially called "Mac OS" instead of "System". Mac OS 7. 6 introduced several features that were also included in Mac OS 8, including a revamped Extensions Manager, more native PowerPC code for Power Macs, more bundled Internet tools and utilities, and an overall more-stable Finder. Mac OS 8 is an Operating system released by Apple Computer on July 26 1997. In this version, the PowerTalk feature added in 7. 5 was removed due to poor application support.
The minor update to Mac OS 7. 6. 1 finally ported the 68k exception handling routines to PowerPC, turning dreaded type 11 errors into less harmful errors (type 1, 2 or 3, usually) as crashing applications would more often terminate safely instead of crashing the operating system. 
Through this period Apple had been attempting to release a completely new "modern" operating system, named Copland. Copland was a project at Apple Computer to create an updated version of the Macintosh operating system. When the Copland project was abandoned in 1996, Apple announced plans to release an OS update every six months until Rhapsody (which would later evolve into Mac OS X) shipped. Year 1996 ( MCMXCVI) was a Leap year starting on Monday (link will display full 1996 Gregorian calendar) Rhapsody is the code name given to Apple Computer 's next-generation Operating system during the period of its development between Apple's purchase of NeXT Mac OS X (mæk oʊ ɛs tɛn is a line of computer Operating systems developed marketed and sold by Apple Inc, the latest of which is pre-loaded on all currently Two more releases were shipped, now officially branded as the "Mac OS" — Mac OS 7. 6 and the minor bug fix 7. 6. 1. Future versions were released as Mac OS 8–8.6 and Mac OS 9–9.2. Mac OS 8 is an Operating system released by Apple Computer on July 26 1997. Mac OS 9 is the final major release of Apple's "Classic" Mac OS.
Apple created and published an "Older Software Downloads" page on their AppleCare Support website on July 17, 2001.
