There is nothing more epic that's California themed than Mavericks.
From what I remember, I did enjoy James Gardner in reruns of Maverick.
For the rest of us not living in CA and don't remember the show or sports teams, mavericks are the ones who tend to cause one trouble, like when they fired upon me from 10 miles away. I would have expected more research in choosing a well known positive sounding name.
Redwoods, Sequoias, Gold Rush, Disneyland, bubble headed bleach blonde, Muscle Beach, Golden Gate, Hollywoodland, Santa Cruz, Alcatraz, SUV, and Terminator are all more California sounding to outsiders than Maverick. This is especially true of Vitamin-D deprived support staff personnel, such as myself. Focus group across the country prior the OSX announcement and ask, "Which one is more California? Maverick, or Reno?", and Reno likely would have won.
They
should call it Sea Lion. I know I am going to. Apple can then transition later to mammals or sea life.
