Wondering what the name of the latest version of MacOS is? Curious about the versions of Mac OS X that came before? Here we'll fill you in on the names of the different versions of the Mac operating system as well as the code-names that Apple used for them, as well as how you can check which version you are running and find out what the latest version of macOS is.
If you look back at previous iterations of macOS and Mac OS X, a clear pattern emerges. With the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were all named after big cats, from Cheetah to Panther to Mountain Lion.
But while the public-facing builds were named after big cats, internally, they were named after wines (with the exception of OS X 10.6 and macOS 10.13, both of which had no code-name).
Even after Apple switched public-facing code-names to places in California back in 2013, it carried on naming them after wines internally until 2014. In 2015, Apple decided to change the theme of internal code-names from wines to types of apple. Original.
Then, in 2016, Apple took the plunge to unify the branding of its’ operating systems by rebranding Mac OS X to macOS, which sits nicely alongside iOS, tvOS and watchOS.
Below, you can find a complete list of OS X version code names, along with internal code names (if available).
