You probably know that Mac OS X 10.5 is known as “Leopard.” You might also know that 10.6 is called “Snow Leopard.” Turns out that Apple has used the name of a large cat as a code name for every version of Mac OS X, starting with “Cheetah” for version 10.0. Meow!
Here’s the entire list. Memorize it and impress your friend(s) with your trivial Macintosh knowledge!
Mac OS X 10.0: Cheetah
Mac OS X 10.1: Puma
Mac OS X 10.2: Jaguar
Mac OS X 10.3: Panther
Mac OS X 10.4: Tiger
Mac OS X 10.5: Leopard
Mac OS X 10.6: Snow Leopard
UPDATE:
Mac OS X 10.7: Lion
Mac OS X 10.8: Mountain Lion
