Follow below methods to Create Bootable USB Drive of Mac OS X 10.9 Mavericks Installer.

Method 1:  Using Terminal

In the earlier version of Mac OS, the easiest method for creating a bootable USB drive is using a Disk Utility tool, but you can’t use the Disk Utility tools for the latest version OS X 10.9 (Mavericks). Since we are not using Disk Utility to create a Bootable USB Drive of Mac OS X 10.9 Mavericks, we’ll have to resort to the terminal application on your Mac.

Step 1: Download the latest version of Mac OS X10.9 Mavericks from the Apple Mac Apps Store

Download Mac OS X10.9 Mavericks

  • If you haven’t installed Mavericks on your Mac yet, then download click the download link and download it but don’t run the installer.
  • If you have already installed Mavericks on your Mac, then download the installer again and don’t run it. The download file called Install OS X Mavericks should be in your Applications folder. Let it be there.

Step 2:  Format USB Flash Drive

The Mavericks installer file is over 5GB, so you need a formatted USB flash drive of 8GB in size. Format your USB flash drive once. Now plug-in your USB drive and open Disk Utility, this is just to format your USB flash drive. Select Your Flash drive from the left side in Disk Utility and click on Erase tab > Erase button. Once again click the Erase button to repartition the drive.

Note: Make sure that the format is Mac OS Extended and the name as Untitled.

Step 3: Making the Bootable USB Drive

Open Terminal – you can find this in > Utilities  Folder > Applications or use Spotlight search. Once the terminal is opened copy the below command and paste it in the terminal and hit enter.

sudo /Applications/Install\ OS\ X\ – -volume /Volumes/Untitled – -applicationpath /Applications/Install\ OS\ X\ – -nointeraction

Now it will ask you to enter your administrative password. Type the password and press enter.

Note: To proceed you must type the password, if you don’t have an administrator password set up on your Mac. Then set up a password first and then proceed.
  • The terminal will now initialize the process by erasing the drive again and copying the files to it.
  • If everything went right then, you should see a message “Copy complete” and “Done.”
Note: The above process may take up to 2 hours to complete successfully (min 25 minutes).

Congratulations! Now you have successfully created a Bootable USB Flash drive of Mac OS X 10.9 Mavericks.
