-[Apple|AppleCorporation] [Macintoshes|AppleMacintosh] run their own
OperatingSystem, also made
by [Apple|
AppleCorporation]. They are collectively known as MacOS, although there are several major versions.
-Version 7 was around at the time of windows 3.1, but everyone chose the inferior system anyway... Versions 8.5 through to all versions of 9 is the more familiar look and feel, and the latest, [Mac OS X|MacOSX] (pronounced OS ten) is a complete re-write that has a FreeBSD and Mach based kernel
.
+A family of
OperatingSystem~s developed
by AppleCorporation for their AppleMacintosh
.
-Initially written for
the [Motorola
] [68000|68000] [CPU],
the later versions (up until
[Mac OS X|
MacOSX]) never supported such things as ProtectedMemory. Support for the [PowerPC] was hacked in to System 7.5. The promised rewrite for the [PowerPC] (codenamed [Copland]) was supposed to be System 8, but it was so late that eventually [Apple] cancelled it and bought [NeXT] instead. The [NeXT] engineers effectively rewrote [NeXTStep], incorporating a few features from [Copland] (such as [Carbon]) and took so long that [Apple|AppleCorporation] might as well have just finished [Copland]
.
+It has two major branches,
the old
[MacOS
] Classic family and
the new
[MacOSX] family
.
+[MacOS] Classic shares many overall design choices with the later MicrosoftWindows (prior to Win32.) It used CooperativeMultitasking and lacked ProtectedMemory, so any application could crash or freeze the entire system. It was initially written for the [Motorola] [680x0] [CPU] architecture, but System 7.5 was hacked to run on [PowerPC]. System 8 was supposed to be a full [PowerPC] rewrite, but the rewrite effort codenamed [Copland] was so late that eventually [Apple] cancelled it and bought [NeXT] instead. The [NeXT] engineers effectively rewrote NeXTStep, incorporating a few features from [Copland] (such as [Carbon]), and created [MacOSX]. It took so long that AppleCorporation might as well have just finished [Copland]. System 8.5 through 9 sport the familiar LookAndFeel.
