The first Mac OS X 10.0 was called "Cheetah" it was released in 2001.

What operating system was coined the operating system of the century?
The first operating systems were nothing like modern operating systems and were usually called batch monitors, because all they did was automatically ran jobs sequentially in batch mode. Computers of the time had no interactive mode of operation. Computer companies did not supply software of any kind with their machines, so it was usually up to the user (company, university, government office) to write all their own software. The first batch monitor/operating system was done in 1954 by MIT for their UNIVAC 1103. General Motors did one in 1955 for their IBM 701.The first computer to come from the manufacturer with an operating system already installed is a different question.
D.O.S (Disk Operating System)
The Macintosh operating system was created by Apple in 1984, which was incorporated into a computer called the Macintosh 128k. If you meant the first creators of the company Apple, then it would be Steve Jobs and Steve Wozniak.
Apples first operating system was Apple DOS 3.1 for the Apple II in 1978. Versions 1 and 2 were internal testing versions and were not made available to the public. They developed Apple SOS (Sophisticated Operating System) for the Apple III in 1980. Parts of the SOS were used in the Lisa's operating system which in turn would lead to the Macintosh Operating System. The first operating system for the Macintosh came out in 1984, with the release of the first Macintosh. This was known as "System 1.0". The current series of system software, Mac OS X, was released in 1999 for servers, and 2001 for desktops.

The Mac OS was designed by Apple as the operating system for their Macintosh range of computers. The first Mac OS, originally known as System Software, was introduced with the first Macintosh in 1984. Over the years the original Mac OS was developed, improved and expanded until Mac OS 9 in 2001. For version 10 Apple reworked the Mac OS around a UNIX core and this is known as Mac OS X.
Hardware-wise, modern Macintosh share 99.9% of the same hardware with any other consumer PC. The first Macintosh shared little with the PCs of the day, other than some standard ports for printers and serial cables. The only thing that truly differentiates the hardware these days is that Macintosh use EFI as their firmware, while PCs use a BIOS designed to be largely compatible with the first PC. Even this is starting to change. Software-wise, modern Macs use a more robust operating system, known as Mac OS X. The first Mac operating systems lacked even the concept of multi-tasking in a meaningful way. Most of the operating system was also stored on a chip along with the firmware. Modern Macs keep all of the actual operating system on-disk.
The year that the first Apple Macintosh computer made its debut was 1984. It had the operating system Mac OS 1.0, and it featured a black and white monitor with a 3.5-inch floppy drive.
MacOS is a very old operating system. The first Macintosh computers were made in 1983, and MacOS was published with them. However, MacOS was developed since the 1970s.
Apple Macintosh
Probably the Xerox one for their experimental prototype Alto computer workstation. That inspired Jobs and Wozniac of Apple to make the one on the Lisa, then the Macintosh.

DOS: Disk Operating SystemTOS: Tape Operating System, most likely came first.It used 1/2 inch 7 channel tapes on computers without harddisks.Before that IBM had a system called IBSYS on their 7090 & 7094 computers, but it was more of a Batch Monitor than a real Operating System (it only automatically ran jobs one after another in batches).
