Os Mavericks Bootable Usb


In a previous post I went through the lengthy method of creating a bootable USB Flash drive that could be used to install OS X Mavericks as well as a really simple solution that involves using an application called DiskMaker X.

  1. An empty USB drive (6 GB or larger): In this guide, you will write Niresh onto a USB drive, and boot your computer from that drive to install OS X Mavericks. The USB drive must be at least 6 GB in size. Since you will need to erase all of the files on the USB drive, make sure to back up its contents first.
  2. OS X Mavericks is now available to everyone as a free download, and while you can update as many Macs as you want by downloading the installer repeatedly from the Mac App Store, a better option for many is to create a simple bootable USB install drive.
  3. Nov 06, 2013 Using a Mac with at least OS X 10.6.8 installed, access the Mac App Store and download the Mavericks (10.9) app installer. Insert the USB drive into the Mac and launch Disk Utility.

This post will go through another method that utilizes a single Terminal Command.

Once you fill out and complete the Mavericks OS account info, the Mavericks OS will automatically be the OS that will open on the iMac. The above window shows the actual Mavericks OS folders that were now installed on to the USB Flash Drive. This is the 'About This Mac' info window for the newly installed Mavericks OS.

#1 – Download OS X Mavericks


First things first, you need to download OS X Mavericks. This is a FREE download from Apple. Here’s link to it: OS X Mavericks

#2 – Prepare your USB Flash Drive

Creating a bootable USB drive for Mavericks requires a USB drive with at least 8GB of available space.

Before we can restore Mavericks onto the USB Flash drive, the drive has to be properly formatted.

To format the USB drive open Disk Utility (located in Applications/Utilities). Plug the drive in into your Mac.

  1. Select the USB Flash drive from the sidebar in Disk Utility.
  2. Select the “Erase” tab.
  3. Make sure the Format is set to Mac OS Extended (Journaled).
  4. As for the name, leave it as “Untitled”.
  5. Finally click the Erase tab.

One important note about Step 5, this will erase everything that is currently on your USB drive.


#3 – Terminal Command

Now that the USB drive is properly formatted we can run the Terminal command that will take care of the rest. Terminal can be found in the Applications/Utilities folder.

Simply copy and paste this into Terminal and press the Enter key on your keyboard:

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

Since the above command uses the sudo atritubute you will be required to enter your password to start the process.

Once the process starts you will see this in Terminal:

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

This process can take a while since it’s coping gigabytes of data over. Leave it alone and let it do its things.

There are many ways that you can create a bootable Mavericks USB Drive but this seems to me the far easiest way to do so. In this article I will assume that you already have a reasonable grasp of the OSX system and cut out the lengthy text:

1. Download Mavericks

Mavericks can be downloaded directly from Apple here (make sure you leave the file in the default download location)

2. Prepare a USB Flash Drive (Must be 8Gb or larger)

  • Plug the USB Drive in to your Mac and open “Disk Utility” (found under applications / utilities in finder)
  • Select the USB Drive
  • Select the Erase tab
  • Ensure that the format is Mac OS Extended (Journaled)

IMPORTANT – Leave the name as “Untitled”. If you change this the next step won’t work

3. Create the Bootable Mavericks USB Drive

Open up Terminal (found in applications)

Type this in:

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