Mac OS Versions with Code Names

Apple has always used public-facing code names for macOS — née OS X — starting with the original, bear-branded beta.

From 2001 to 2012 they were all code-named after big cats. However, because Apple marketed co-opted the internal code-names, in 2003 the internal code-names switched to wines (with the exception of OS X 10.6, which never had a code-name beyond Snow Leopard).

Though OS X marketing code-names switched to California places in 2013, the internal code-names remained wine-based until 2014. In 2015 they switched to types of apples.

In 2016, they switched the OS X name to macOS, but kept with the apple.
