OS X Yosemite USB Install

Here's a simple way to create a USB install disk for OS X Yosemite!

First, download Yosemite from the app store, then format your 8GB+ USB drive in Mac OS Extended (Journaled) format. I'll be using a Lexar P10 USB 3 32GB drive in this example (I highly recommend a USB 3 drive for this install)

Second, run the following command below in the terminal to create the install USB drive. This assumes that the Yosemite installer is in your Applications folder and that your USB drive is labelled Untitled.

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction

Your USB drive should now be labeled "Install OS X Yosemite". To boot from this drive, hold down the Option key when booting your Mac and select the USB drive.
