With the development of OS X 10.9 Mavericks finally finished and the release only a few weeks away, I thought I would share the quickest and simplest way to create a bootable USB drive. This process will allow you to complete a clean install of OS X Mavericks once it's publicly available.
I had previously shared a manual process to clean install the developer preview, but this is my new preferred method, requiring only one command.
To start you will need an 8GB USB drive and access to the Mac App Store download of OS X Mavericks. Once downloaded it's simply a case of inserting the USB drive, opening Terminal and running the following command:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/LifeinTECH
--applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
The only part of the command that must be changed is the name of the USB drive (e.g. bold and underlined above).
This command will automatically erase the USB drive and install a bootable version of OS X Mavericks. The entire process can take up to 15mins without any indication, however it will prompt once the process is complete (see the image below).
You can now restart your Mac and hold the "Option" key during startup. This will allow you to boot from your newly created USB drive and clean install OS X Mavericks. Enjoy!
