Code Names of OS X...

in macOS edited January 2014
Okay, so we all knew about Puma, Cheetah, and such.

Some of us even knew that Kodiak was the codename for the Public Beta.

But did you know that the three developer releases before that were, in order, Beaker, Bunsen, and Gonzo?

And an alternate codename for Rhapsody was Teflon? (As well as the Hera and Atlas build distinctions...)

It's amazing what one finds when dumpster diving in the CVS directories for Darwin.

    I didn't feel like posting an entire thread on this, but:

    I think Apple's going to get away from numbers in their naming scheme. I think OS X will remain under that name, and future releases will be the "code name" they give them.

    "Now available, OS X Jaguar"

    "Coming soon, OS X Congo" (or whatever)

    That seems confusing enough.

    Was Orient just a total work of fiction by the rumor mills, or is it actually the next step after Jagwire?
