TUAW shows you how to install Yosemite on a USB 3.0 flash drive
OS X Yosemite has a lot of people excited, and for some good reasons -- a new, more iOS 7-like UI, AirDrop that works with iOS, calling from Mac, and a host of other really useful and fun new features. Developers are already testing the new OS, and the general public can begin testing soon in an open consumer beta. But you should never, ever install a beta operating system on a production machine -- otherwise known as "my only Mac" or "the Mac they gave me at work". Instead, you can easily install Yosemite on a USB 3.0 flash drive and have your development/testing operating system available in your pocket just a reboot away.How to install Yosemite on a USB 3.0 flash drive
