OS MAC version

   Apple has always used public-facing code-names of Mac 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 Here are all of them, past, present, and currently in development.
