Creating a Yosemite Installation Boot Disk

OS X Mavericks

One of the jobs I do after a new Mac OS X release is to create a bootable install disk.  Generally this takes a little effort with some messing about in the terminal and with disk utility but it seems Apple have created a little utility to do the job for you.

Basically fire up the command line, switch to an admin level use then just type the following:  (assuming your blank media is called Untitled)

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

That is all you need to do.
