If we turn our attention to the early macOS and Mac OS X operating systems, we can see that a pattern was followed from the very beginning. With the exception of the first OS X beta, all versions of the Mac operating system from 2001 to 2012 were named after big cats, such as Cheetah or Panther.
Although feline names are used publicly, wine names are used internally in the company (with the exception of OS X 10.6 and macOS 10.13, the two systems that did not have any code names).
Even after Apple changed the code names to California sites in 2013, wine names continued to be used internally until 2014. In 2015, Apple changed the code names again, this time to apple type names.
A year later, in 2016, the apple company decided to unify the brand of operating systems from Mac OS X to macOS, thus unifying with operating systems of other Apple products such as iOS, tvOS or watchOS.
Below is a complete list of the public code names of OS X versions, along with the code names that were used internally (if any).
