Having a bootable USB flash drive of your operating system is a very useful tool to have around for diagnostics, maintenance or fresh clean installs of your OS. In the past few versions of OS X, if you wanted to create a bootable USB stick, you had to do a little bit of Erica Sadun-style nerd wizardry or download a third-party tool like Lion Disk Maker to create one. Luckily with Mavericks, Apple has included a tool to allow us to create a bootable USB flash drive with a few simple terminal commands.
This video will show you how to do it, so go grab an 8 GB or larger USB stick and follow along.
