    I have a unibody MacBook. Is it possible to install Mac OS X on a USB external hard drive and use that to boot?

    Yes as long as it's formatted Mac OS Extended (Journaled) and has a GUID partition table.

    Ah, thanks.
    Works great; I'm running OS X on my external drive at this very moment :)
