Boot from USB external hard drive?

[EricJD]

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
