Burn OS X Mountain Lion to DVDAh, the versatile DVD! We think it is so old fashioned, but really, it keeps so much going – specifically the software that we love to use on all our devices. You can download the OS X Mountain Lion from Apple’s App Store at any time after you have purchased it, but it is always useful to have a bootable disk at your disposal. You will not always be in a position to re-download the installation package every time you want it.

First, you need to download the OS X Mountain Lion to your Mac system. However, do not install it now, unless you understand the different options to install it. I will go over the download options below:

Using Lion Disk Maker

This is the simplest of them. Follow these steps to create an OS X Mountain Lion bootable DVD or USB flash drive using the Lion Disk Maker:

  • Installation media- you need at least 8 GB. So use an 8GB USB flash drive or SD card or a dual layer DVD because a single layer DVD has only 5GB space.
  • Download Disk Maker- the latest version is 2.0rc2. Install it
  • Run and it will show you the Mountain Lion request that is downloaded to your Mac. Click ‘Create a Boot Disk’ using SD cards or USB flash drives or ‘Burn a DVD’ as the case is. Soon you have everything.

Using the Built-in Disk Utility

You can also burn the OS X Mountain Lion using Apple’s disk utility. Here, is how:

  • Look in Applications folder for the Mountain Lion installer. Right click on it and select ‘Show Package Contents’.
  • Find the file ‘InstallESD.dmg’ from SharedSupport inside Contents.
  • Open Disk Utilities from the Utilities folder in Applications.
  • Drag and drop the DGM file into the left sidebar of the Disk Utilities window.
  • If you are burning to a DVD:
    • Insert the disc in the DVD tray
    • Select the DMG file in the left sidebar
    • Click on ‘Burn’
  • If you are burning to a USB disc or SD card:
    • Insert the disc. Take care that there is no relevant data in it as it may get erase.
    • In the Disk Utility select the disc in the sidebar
    • In the Partition tab, select ‘1 Partition’
    • Choose ‘Mac OS Extended (Journaled)’ as the format type
    • Click on options and choose ‘GUID partition table’
    • Hit apply, and the disc will be formatted for installing the Mac in it
    • Now in the Restore tab, select the source as the DMG file and the disc as the destination.
    • Click on ‘Apply’

Now you are done with it and thus succeeded in creating an OS X Mountain Lion bootable disk.
