HOW TO Create a Maverick (OS X 10.9) USB Installer


 

From Terminal (command line)
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

The only thing you may need to adjust is the name of your destination volume which may be called “Untitled 1” by default unless you named it s.th. else —so use “Untitled” or whatever name you gave it.

C’est tout.
