How To Create An OS X Mavericks USB Installation Drive

OS X Mavericks is available in the Mac App Store now, but it's only an upgrade . If you want to do a clean install, you'll need to manually burn an installation flash drive. Here's how to do it.

Sadly, the old method for Lion and Mountain Lion doesn't work anymore, but thanks to MacRumors forum user tywebb13, we have another simple method for Mavericks. Here's what you need to do:

  1. Insert your USB drive (you'll need one that's 8GB or larger) and open Disk Utility.
  2. Select your drive in the sidebar and go to the Erase tab. Format the drive as "Mac OS Extended (Journaled)" and name the drive "Untitled".
  3. Click the Erase button and wait for Disk Utility to finish.
  4. Close Disk Utility and open up a Terminal window. Type the following command into the Terminal:

  5. Press Enter. The process should take about 20 minutes, so don't cancel it or eject your USB drive while it's doing its thing.
  6. When it's done, you should see a message stating the process is finished. Now, you can restart your computer, hold the Option key to access the boot menu, and select your new USB drive to install a clean copy of OS X Mavericks.

Check out the video above to see the process in action, and good luck! Check out our overview of Mavericks to get started with the OS — that is, if you want to upgrade at all.

    Do you have to do the Mavericks upgrade first?

      Nope. Once you download it through the App Store, it will run the application, but you can quit the installer by pressing cmd+q. This is important for Hackintoshes because you need to patch some files before you run the installer.
