How to create a bootable OS X Mavericks USB install drive?


Apple has released the latest version of their desktop operating system OS X 10.9 Mavericks. It is available free to download from Apple App Store. For installing Mavericks, you have to create OS X USB installer. 


To create bootable OS X Mavericks install drive:
1.Firstly, download OS X Mavericks installer from the App Store but don’t run it. In case, you have already upgraded then you have to download the installer again from the App Store as this installer gets deleted after the upgrade. Locate the installer in Applications folder.
2.Now, you need to format USB flash drive of at least 8GB and keep its default name as “Untitled.” Check out that you don’t have another volume with same name. If you find one then rename it temporarily. Also, you can name your USB flash drive with some other name. But, don’t forget to change the command in Step 3 to show the correct name.

3.Enter the following command by opening a terminal window:
sudo /Applications/Install\ OS\ X\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ –nointeraction
After this, you need to enter your password to continue. It will take only 20 minutes or more to complete.

Congrats! Now, you can boot with the USB installer while holding down the Option key and start installation of OS X Mavericks. If it gets stuck at "Copying installer files to disk," try with different USB flash drive. In case, your USB installer is not appearing in Startup manager then also try to switch to a different USB flash drive.
