    I've made bootable USB installers from various versions of the Yosemite installer from the App Store over time. It's my understanding when I upgrade a Mac, the store always downloads the latest Yosemite available at the time so I know my sticks have 10.10.2 or .3 or .4, but don't know which are which.

    Is there some way of identifying which subversion of Yosemite that stick has?

    Just checked the OS X Installer apps (start app -> about OS X installer):

    OS X Installer 10.10.0 has version number 1.6.5 (1012)
    OS X Installer 10.10.1 has version number 1.6.7 (1014)
    OS X Installer 10.10.2 has version number 1.6.10 (1017)
    OS X Installer 10.10.3 has version number 1.6.16 (1023)
    OS X Installer 10.10.4 has version number 1.6.30 (1040)

    or, boot the stick and start the terminal. enter "sw_vers" hit enter. this will give the OS version and build number. or insert the stick in a Mac and start System Preferences. go into Startup Disk. this also will show version (and build number if you hover the mouse pointer over the stick's icon).

    Do you know if I can just copy the most current "Install OS X Yosemite" file onto the other (older) Yosemite bootable USB sticks and overwrite the existing file, or do I have to reimage the most current stick onto the others?

    I'm not sure if there is anything special about the "boot loader" amongst the various versions of Yosemite.

    Even easier, I can just do a "get Info" on the installer file and it tells me the correct version number. :)
