Mac OS X 10.0 Cheetah: A Major Turning Point in Apple's Operating System History

The release of Mac OS X 10.0 Cheetah in March 2001 marked a significant milestone in the history of macOS, Apple's current operating system for Mac computers. This major version number change signaled a departure from the classic Mac OS and introduced a new, Unix-based operating system that would eventually become the standard for Apple's computers.

The development of Mac OS X began as a project to replace the 'classic' Mac OS, which had been used in Apple's Mac computers since their introduction in 1984. The company acquired NeXT, a technology firm founded by Steve Jobs, in early 1997 and incorporated its technologies into the new operating system.

Mac OS X 10.0 Cheetah was built using these NeXT technologies but did not include the signature Aqua user interface, which would become a hallmark of future versions of macOS. Instead, the operating system had a more basic look and feel, although it still offered many improvements over its predecessors.

One major change introduced in Mac OS X 10.0 Cheetah was the ability to run Mac OS 9 applications using a compatibility layer. This made it easier for users to transition from older versions of the Mac OS to the new operating system. However, this layer would eventually be phased out as future versions of macOS became more capable of running older applications natively.

The release of Mac OS X 10.0 Cheetah was followed by several more major releases, each with its own set of features and improvements. Today, macOS is a Unix-based operating system that has undergone significant changes over the years, including a name change from 'Mac OS X' to simply 'macOS' in 2011.

Despite these changes, Mac OS X 10.0 Cheetah remains an important milestone in the history of Apple's operating systems, marking the beginning of a new era for macOS that would eventually become one of the most popular and widely-used operating systems in the world.
