Mac OS X Public Beta expired and ceased to function in Spring 2001. On September 13, 2000 Apple released a $29.95[9] "preview" version of Mac OS X (internally codenamed Kodiak) in order to gain feedback from users.[10]

Cheetah

Mar 24, 2001

On March 24, 2001, Apple released Mac OS X v10.0 (internally codenamed Cheetah).[12] The initial version was slow, incomplete, and had very few applications available at the time of its launch, mostly from independent developers.

Simply releasing Mac OS X was received by the Macintosh community as a great accomplishment,

Apple released 10.1 as a free upgrade CD for 10.0 users, in addition to the US$129 boxed version for people running Mac OS 9.

Aug 23, 2002

On August 23, 2002,[16] Apple followed up with Mac OS X v10.2 Jaguar, the first release to use its code name as part of the branding.[17] It brought great raw performance improvements, a sleeker look, and many powerful user-interface enhancements (over 150, according to Apple[18] ), including Quartz Extreme for compositing graphics directly on an ATI Radeon or Nvidia GeForce2 MX AGP-based video card with at least 16 MB of VRAM, a system-wide repository for contact information in the new Address.

Version 10.6 'Snow Leopard'

Aug 28, 2009

Mac OS X v10.6 Snow Leopard was released on August 28, 2009. Rather than delivering big changes to the appearance and end user functionality like the previous releases of Mac OS X, Snow Leopard focuses on "under the hood" changes, increasing the performance, efficiency, and stability of the operating system. For most users, the most noticeable changes are: the disk space that the operating system frees up after a clean install compared to Mac OS X 10.5 Leopard, a more responsive Finder rewritten
