Create bootable OS X Maverick USB Flash Drive

Create bootable OS X Maverick USB Flash Drive from original App Store Mavericks 10.9 package.

1) Erase a minimum 8GB USB pen drive using Disk Utility* and ensure it’s named ‘Untitled’ and Mac OS Extended (Journaled) format.

2) Download OS X Mavericks from the Mac App Store. It’ll download and save to the Applications folder automatically. Furthermore, after it’s finished downloading, it may automatically begin the install process. If this happens, just quickly cancel it.

3) Run the below command in Terminal** window:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

4) Type your current user password.

The application will erase your USB pen drive first, then write Mac OS X Mavericks files making it bootable. The result of burning image into USB should be as follows:

Password:
Erasing Disk: 0%… 10%… 20%…100%…
Copying installer files to disk…
Copy complete.
Making disk bootable…
Copying boot files…
Copy complete.
Done.

** – in order to run Terminal press CMD + Space, type Terminal and click/select to run. Alternatively go to Applications > Utilities, find and run Terminal from there.

    • Should be fine now i.e. have tested copying and pasting into Terminal and it started burning my Apple Mac OS X Mavericks 10.9 into USB Flash Drive. Please let me know if you experience any problems. Ta for letting me know. D

  1. I am running a danish Mac OS version and folders are named differently. I have tried to replace “Applications” with “Programmer” in the command above, but that results in “command not found”. Do I need to replace anything else, to make this work with my local language version of Mac OS?

    • I would remove the whole ‘/Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia’ and start typing /Progr hit Tab key to complete then type next part of the path that’s equivalent to ‘Install’ in your language hit tab again and continue doint that until you get to the last ‘createinstallmedia’. Same applies for /Volumes/Untitled which may differ in other languages. Tab key basically will autocompelete for you the correct path.

    • You’ll need a Dual Layer 8GB DVD in order to burn the image:

      1) Search in Spotlight (cmd+space) for ‘Install OS X Mavericks.app’.
      2) Click on ‘Show All in Finder’ at the top.
      3) Find ‘Install OS X Mavericks’ package, right click and choose ‘Show Package Contents’.
      4) Navigate to ‘SharedSupport’ folder
      5) Right click on InstallESD.dmg and select Burn “InstallESD.dmg” to Disc… (this should burn file’s contents although still need to test it).

  2. Many thanks, it worked perfectly. Well, it didn’t work at first, but that’s because I had not begun by downloading Maverick. So I did, following these instructions:

    “Download OS X Mavericks from the Mac App Store. It’ll download and save to the Applications folder automatically. Furthermore, after it’s finished downloading, it may automatically begin the install process. If this happens, just quickly cancel it.”

    And then, the Terminal command worked perfectly.

    Thank you again!

    • That’s a very good point! I should have never assumed people have already downloaded the new OS X. I’ve added your paragraph to my text – thank you very much.
