    I have a mid 2012 MBP running Yosemite not the public beta. Ever since I upgraded to Mavericks my computer will not restart. It'll show a screen with just the dock and I have to hold down the power button until it shuts off. Anybody else have this problem?

    Two thoughts:

    1) you can't "upgrade" from Yosemite to Mavericks. That's going backwards - downgrading. Is that what you meant?

    2) You probably need to boot to Recovery Mode and reinstall the OS. See https://support.apple.com/en-us/HT4718

    I would agree with this course of action. :)

    If in doubt, clean install.

    Sorry bad wording on my part. I meant the problem has been consistent since I upgraded to Mavericks and has continued with my upgrade to Yosemite

    Then I would definitely recommend a clean install of Yosemite.

    Please tell me you have a complete time machine backup of your mac?

    Well then, you probably don't have very many options. A reinstall is probably the safest course of action. If you are hesitant to do that, there is one thing you can try first--safe boot (see https://support.apple.com/en-us/HT201262). If the machine will safe boot, then you can troubleshoot a bit more and possible fix the problem. Still, reinstalling from recovery mode is easiest.

    I don't. That's why the clean install isn't really an option for me

    Not having a backup is a recipe for disaster :/

    Especially considering how cheap a 1TB portable hard drive is.

    Reinstalling the OS won't destroy your data. Just reinstall, don't format or erase the drive first.
