[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.

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].
