    I'm creating my bootable Yosemite install disk now (I want a fresh install).

    I noticed something strange. When I open the contents of the installer app and look in the .plist file, it says build number 14A387. I thought i was supposed to be 89. The last developer candidate was name 88b, I think.

    What build numbers do you guys have out there?

    14A388b was the last public beta
    14A389 is the public release currently in the app store

    Don't worry about 14A387. Technically it's an alpha (albeit a rather advanced alpha) - one which was never released to anyone. It is what was used to make the final version with build 14A389.
