Mac OS is the trademark-protected name for a series of graphical user interface-based operating systems developed by Apple Inc. (formerly Apple Computer, Inc.) for their Macintosh line of computer systems. The Macintosh user experience is credited with popularizing the graphical user interface. The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.

Apple deliberately downplayed the existence of the operating system in the early years of the Macintosh to help make the machine appear more user-friendly and to distance it from other operating systems such as MS-DOS, which was more arcane and technically challenging. Much of this early system software was held in ROM, with updates typically provided free of charge by Apple dealers on floppy disk. As increasing disk storage capacity and performance gradually eliminated the need for storing much of the advanced GUI operating system in the ROM, Apple explored clones while positioning major operating system upgrades as separate revenue-generating products, first with System 7.1 and System 7.5, then with Mac OS 7.6 in 1997.

Early versions of the Mac OS were compatible only with Motorola 68000-based Macintoshes. As Apple introduced computers with PowerPC hardware, the OS was upgraded to support this architecture as well. Mac OS 8.1 was the last version that could run on a 68000-class processor (the 68040). Mac OS X, which has superseded the "Classic" Mac OS, is compatible with both PowerPC and Intel processors through version 10.5 ("Leopard"). Version 10.6 ("Snow Leopard") supports only Intel processors.

What is the easiest way to install Mac OS X on a PC?
Q. I have a Windows Vista computer and would like to install Mac OS X Leopard on the PC. I have an original copy of Leopard with me, but I wonder whether there are any softwares that aid the process or helps me install Mac OS X on a PC, like what Wubi ( does. If not, what alternatives are there to do likewise?

A. The fact that you "have an original copy of Leopard" doesn't matter, OS X only runs on Apple hardware. Any attempt to do otherwise is illegal. If you want OS X, BUY a Mac. Then, you can run a legal copy of Windows on a Mac. FYI: No VMware supports the use of OS X, because they'd get their butts sued off! That includes Wubi, though not technically VMware.

Is it possible to install MAC Os on my Compaq laptop?
Q. I want to install MAc os on my compaq laptop which is preloaaded with Windows 7. Is this possible. Do I need some special hardware for installing MAc os.

A. Hmm.. I just bought a compaq presario recently and I think you shouldn't bother considering mac.. I know that it is a true eye candy but with compatibility issues may get along the way of doing it. The bottom line is yes, it can be installed but through hardware virtualization, thus it is not native. Why switch? 7 is a great OS so far.
