OS X Sea Lion (version 10.9) was announced on June 10, 2013 at the 2013 Worldwide Developers Conference. Apple Senior VP Craig Federighi acknowledged the “dwindling supply” of cats during the keynote address.

After suggesting OS X Sea Lion to a mixture of applause and laughing confusion, Federighi concluded that “Sea Lion” would be a “dead end” and announced Apple's intention to begin using California landmarks for at least the next 10 years, beginning with OS X 10.9 “Mavericks”.
