Make Bootable OSX Yosemite USB Install Drive

1. Format drive with the defaults using Disk Utility and name it "Untitled".
2. Download OSX Installer App from Mac App Store (Note: If you use this installer it will not be usable again, so make a copy to ~/Documents).
3. Open Terminal and run:

sudo ~/Documents\Install OS\ X\
 --volume /Volumes/Untitled --applicationpath
 ~/Documents\Install OS\ X\ --nointeraction

4. Go do the computer you want to install Yosemite on.
5. Plug in the USB drive.
6. Turn the machine on and hold down the Option (ALT) key until you get a list of drives.
7. Choose the installer, and follow the directions.
