Scott P. Hall has an interesting theory on the subject:
“Mavericks” isn’t the first of the big landmarks California offers that came to my mind. So, this in turn made me notice a curious thing: Apple did change the naming convention of OS X, but they didn’t bump Mavericks to version 11 … it’s 10.9.
Apple doesn’t do something like that without it having any meaning. The naming convention change makes sense, because…well…Sea Lion? But I believe Mavericks isn’t “the big one”. I believe, say, Yosemite will be 11, or any other of the aforementioned big landmarks California has.
I hadn’t considered this before, but it kinda makes sense. We’ll see what happens.
