Jun 24, 2013 I own a Macbook Air and wanted to extract an OS X 10.8 Mountain Lion InstallESD.dmg from the Air. However as OS X 0.8 Mountain Lion came installed on my Macbook Air i could not obtain the InstallESD.dmg from the App Store.

  1. Sep 04, 2017  Allows zero-config upgrade or reinstall, with app store downloaded installer app, or fresh install, with installer app or official bootable install media, and create bootable Recovery HD.
  2. Oct 22, 2011  When updating to 10.7.2, there's a Lion Recovery Update that goes along with it. This is meant to update your Recover HD recovery partition to 10.7.2 along with your Mac. However, when I tried updating, I could see from the logs that for whatever reason, my Recovery HD was staying at.
  3. In the Finder, open the Recovery HD drive and then open the com.apple.recovery.boot folder, and you should now see a file called 'BaseSystem.dmg.' Drag this to the list of disks in Disk Utility so.
  4. Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

An interesting dilemma, indeed. The configuration of the Recovery HD seems convoluted and backward; why they'd put the entire startup system inside another disk image is beyond me--unless installing extra utilities is exactly what they're trying to prevent. I see two possible solutions:

  1. After backing up BaseSystem.dmg, try using Disk Utility to convert the image to a read/write format. Make your mods, and convert it back. This option, of course, is highly tricky, and it’d be difficult to keep the volume bootable.

  2. Use Disk Utility to create a new (standard, visible) partition in HFS+, and Restore from BaseSystem.dmg to it. You’ll now effectively have two recovery partitions. This new one, though, not being wrapped up in an image, should be free to add files to. It seems like Mac OS X Base System has all the requisite files for starting up from, all the way down to boot.efi. You might have to also jump through a few hoops in order to get it bootable, but it should be far more straightforward than using option 1. Once you’ve done that and tested it thoroughly, you could remove the “official” Recovery HD partition.

How many entities does it need to do dmg. Might I stress: I have tried neither of these, and I’m running purely on speculation based on past experience. Proceed entirely at your own risk, and only if you know exactly what you're doing!
