List Of All macOS Version History (1997 to 2021)

macOS Version History

Last Updated: 28 July 2021

Are you looking for macOS Version History? Well, you came to the right place!

In this article, I’m not going to list the version history of the classic Macintosh Operating System found in the 80s and 90s rather I’m going to list all the latest macOS Version history that you will find on the 20s Apple Computers.

Before we dig deep into the list of version history, let us have a short introduction to MacOS.

Apple had been using the Macintosh Operating System from 1984 to 2001 which included its final release of MAC OS 9 in 2001, the Mac OS X 10.0 (Cheetah) was a direct descendant of the operating system.

Apple used the “MacOs X” term for their operating system from 2001 until 2011 and the “OS X” term from 2012 to 2015. Although it was originally marketed as simply “Version 10” of the Mac OS (indicated by the Roman numeral “X”), it has a completely different codebase from Mac OS 9.

A new macOS namely “Monterey” was announced during Worldwide Developers Conference (WWDC) on 7th June 2021.

Interesting Facts About MacOS


  • MacOS retained the major version number 10 throughout its development history until the release of macOS 11 Big Sur in 2020.
  • MacOS have always been named after big cats (Versions 10.0 – 10.8) or locations in California (Version 10.9 – Present).
  • 32-bit PowerPC applications were supported on Intel processors with Rosetta and 64-bit Intel applications are supported on Apple silicon Macs with Rosetta 2. However, Intel-based Macs are unable to run ARM-based applications, such as iOS and iPadOS apps.
  • For the past 10 years, Apple announces the new macOS on Worldwide Developers Conference (WWDC) held every year in the month of June.
  • MacOS never had a separate left-click or right-click like Windows, whenever you need left-click just make a single click and for a right-click make two consecutive clicks.


APPLE’S MacOS VERSION HISTORY



First Public Beta: “Kodiak”


Like every other Operating System, Apple started its macOS with a preview version of macOS X which is internally codenamed as Kodiak. It was released on 13 September 2000 for $29.95 to gain feedback from users and developers.

Apple made many changes to the UI based on customer feedback, the beta version of macOS X was marked as the first public availability of the Aqua interface. Apple’s Mac OS X Public Beta expired and ceased to function in spring 2001.
