Earlier systems used the lower 24 bits for addressing, and the upper 8 bits for flags.

It also moved the Mac to true 32-bit memory addressing - necessary with the ever increasing amounts of RAM available. System 6 consolidated the previous releases into a much more complete and stable operating system. MultiFinder had been released with earlier systems, but the 6.x systems were the first to make it official and widely used. Time was given to the background applications only when the foreground (or 'running') applications gave it up ( cooperative multitasking), but in fact most of them did via a clever change on the OS's event handling. System 6 added MultiFinder, an add-on replacement for the Finder which could run several programs at once.

System Software 5.1 ( System 4.3, Finder 6.0, MultiFinder 1.0).

System Software 5.0 ( System 4.2, Finder 6.0, MultiFinder 1.0).

System 5 was also the first Macintosh operating system to be given a unified 'Macintosh System Software' version number, as opposed to the numbers used for the System and Finder files. This significantly altered the extent and design of the underlying graphics architecture (and its APIs), but it is a credit to Apple that most users, and perhaps more importantly existing code, were largely unaware of this. The others significant change that System Software 5 brought to the Mac was Color QuickDraw, which debuted with the Macintosh II. System Software 5.0 added MultiFinder, an add-on replacement for the Finder which could run several programs at once. 'System 5' refers to the system software bundle version, not the System software version. The other significant change that System 4.x brought to the Mac was Colour QuickDraw, which debuted with the Macintosh II in 1986. System 3.0 introduced HFS (Hierarchical File System) which had real directories - previously the Finder created the illusion of folders on the flat file system. While adding MMU emulation has been discussed, the feature has not been added because of the effort required in implementing it, the impact on performance it will have and the lack of time on the part of the developers.All of these versions could only run one application at a time, though special application shells such as Switcher (discussed under MultiFinder) could get around this to some extent.

SheepShaver is capable of running Mac OS 7.5.2 through 9.0.4 (though it needs the image of an Old World ROM to run Mac OS 8.1 or below ), and can be run inside a window so that the user can run classic Mac OS and either BeOS, Intel-based Mac OS X, Linux, or Windows applications at the same time.ДЄlthough SheepShaver does have Ethernet support and CD-quality sound output, it does not emulate the memory management unit. 'Chubby Bunny' also simplifies the set up process of OS 9 visualization on Intel Macs running OS X.вЂSheep Shaver WrapperвЂ™ is built off of Sheep Shaver but it does some of the bundling work for the user.

ДЄs a free software, a few variants exist to simplify the installation process on Intel-based Macs: SheepShaver has also been ported to Microsoft Windows. It can be run on both PowerPC and x86 systems however, it runs more slowly on an x86 system than on a PowerPC system, because of the translation between the PowerPC and Intel x86 instruction sets.

SheepShaver was originally commercial software when first released in 1998, but after the demise of Be Inc., the maker of BeOS, it became open source in 2002.
