I want to create a bootable copy of Mountain Lion, and I've been reading instructions on various forums, and they all say to copy the installESD.dmg file that's located within the Install OS X Mountain Lion.app. I was wondering, what is the difference between the two? I know once you install OS X, the app is deleted. What wouldbe the difference between copying Install OS X Mountain Lion to the USB vs copying InstallESD.dmg to the USB?
We also have a complete guide to installing and upgrading to Mountain Lion (OS X. It’s called Install Mac OS X Lion.app and it. You didn’t need to first mount the InstallESD.dmg image.
Thanks very much 🙂
