How to create a bootable OS X 10.9 Mavericks USB drive

Author: By Mihaita Bamburic


  1. Connect the USB drive to your Mac. Backup any files that may be stored on it.
  2. 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).
  3. Open Terminal.
  4. Type (paste) the following command: sudo /Applications/Install\ OS\ X\ --volume /Volumes/Mavericks --applicationpath /Applications/Install\ OS\ X\ --nointeraction.
  5. To kick off the process, type in your user password when requested.
