Mac OS X & macOS names

As you’ll see from the list above, with the exception of the primary OS X beta, all versions of the Mac OS from 2001 to 2012 were all named after big cats, from Cheetah to Panther to Cougar.

But while the public-facing builds were named after big cats, they were named after wines aside from OS X 10.6 and macOS 10.13, both of which had no codename.

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 vary the theme of internal code-names from wines to sorts of apples. Original.

Apple took the plunge to unify the branding of its operating systems by rebranding Mac OS X to macOS in 2016. It sits nicely alongside iOS, tvOS, and watchOS, and paved the way for macOS 11, the successor to Mac OS X, which arrived twenty years after the primary beta of Mac OS X.
