Mac OS X & macOS names

As you can see from the list above, with the exception of the primary SX Beta, all versions of the Mac operating system from 2001 to 2012, from cheetah to panther to cougar, were all cat names.

But when public-facing constructions were named after big cats, internally, they were named after the wines (except for OS X 10.6 and MacOS 10.13, both of which have no codename. Was not).

Even after Apple changed its public-facing code names to locations in California in 2013, it continued to name the wine internally until 2014. In 2015, Apple decided to modify the theme of internal code names from wine to apple varieties. Really.


We find it interesting that in 2019 Apple switched back to a cat-theme with California’s name Catalina (named after the island of California).

In 2016, Apple plans to re-integrate the branding of its OS into Mac OS X with MacOS, which sits alongside iOS, TVs, and Watches.

Here’s the last 10 MacOS names:

  • MacOS 10.14: Mojave- 2018
  • MacOS 10.13: High Sierra- 2017
  • MacOS 10.12: Sierra- 2016
  • OS X 10.11: El Capitan- 2015
  • OS X 10.10: Yosemite-2014
  • OS X 10.9 Mavericks-2013
  • OS X 10.8 Mountain Lion- 2012
  • OS X 10.7 Lion- 2011
  • OS X 10.6 Snow Leopard- 2009
  • OS X 10.5 Leopard- 2007

In Catalina, users will see that Apple is replacing iTunes with its popular entertainment apps — Apple Music, Apple Podcasts and therefore the Apple TV app. The new OS also will include the new Sidecar and security measures. macOS Catalina also gets security improvements to stay hackers cornered.
