    I was in the beta and I did a command r reinstall OS X and not sure if it gave me the latest version or the one I was on previous.

    How do I check? I know there's a number somewhere but can't find it.

    In the middle of several books.
    Click on the Apple symbol in the upper left corner of screen > About this Mac > System report > scroll down to Software (left side) You should see OS X 10.10 (14A389) if you are running the GM.

    Click on the Apple menu, choose About This Mac. Click on Version under OS X Yosemite, which should display the build number. The public release version is build 14A389.

    Thanks folks. I was looking in the right place but wasn't clicking version. I was wondering why the build wasn't there, it just said 10.10, but I indeed had to click it.
