- Connect the USB drive to your Mac. Backup any files that may be stored on it.
- Format it, using Disk Utility, as a Mac OS Extended (Journaled) drive, named Mavericks. This can be done from the Erase tab within the app; make sure the USB drive does not have multiple partitions (that can happen, so turn to the Partition tab to verify and correct this).
- Open Terminal.
- Type (paste) the following command: sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Mavericks --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction.
- To kick off the process, type in your user password when requested.
