How to Create Mountain Lion Bootable USB Drive



A tutorial how to make a Mountain Lion Install USB for installing it on multiple Mac computers or to do a clean install.


Full Instructions:

  1. Download Mountain Lion from the Mac App Store, and do not install it (yet).
  2. Go to Applications folder and right-click the Install Mac OS X Mountain Lion app and click Show package contents.
  3. Go to the Contents > SharedSupport folder and locate the file called InstallESD.dmg.
  4. Open Disk Utility and drag the InstallESD.dmg image to the device sidebar.
  5. Insert your USB that has more than 4 GB. Add a partition with 4.8 GB with format Mac OS Extended (Journaled).
  6. Select the InstallESD.dmg file in Disk Utility and click the Restore tab.
  7. Drag your Mountain Partition to the Destination field, and then click the Restore button. Once it is complete you should have a fully bootable Mountain Lion install drive. (If there is an error it should still work)
If you have any questions, feel free to comment below or on my youtube video.



Mac OS 10.8 Mountain Lion has officially released today July 25, 2012. Mountain Lion is available for download right now in the Mac App Store for only $20. The price is a really good deal, comparing to the $30 price tag for Mac OS X Lion that came out last year.

Many new features, over 200, come with Mountain Lion for mac users. You can see my first look impressions here. After using Mac OS X Mountain Lion for a couple weeks I am definitely satisfied. One of my favorite features is the notification center and the twitter integration where you can tweet directly from the notification center.

I cannot wait for facebook integration to come out for Mountain Lion users in the fall, also with iOS 6 for Apple devices. A complete review of OS X Mountain Lion coming soon!
