Using an updated installer is convenient, because it means that if you ever need to re-install Mountain Lion, you won’t have to install 10.8.0 and then immediately install the latest big update.The initial Mac App Store version of Mountain Lion will boot only those Macs released prior to Mountain Lion’s debut—Macs released after Mountain Lion’s debut will ship with a newer version of Mountain Lion preinstalled. For example, when the inevitable 10.8.1 update is released, a few days later the Mac App Store will begin providing an updated Mountain Lion installer that installs 10.8.1 right off the bat. Which means that a bootable install drive you create from that installer will install OS X 10.8.0.However, unlike with the CD- and DVD-based Mac OS X installers of old, which can never be updated once they’re created, Apple regularly updates the Mountain Lion installer on the Mac App Store so that it installs the latest version of OS X 10.8.

So if you buy a new Mac post-Mountain Lion, and you haven’t purchased Mountain Lion for another Mac, you can’t download the Mountain Lion installer from the Mac App Store.

The latter is easier, but the former doesn’t require you to download third-party software. ![]() Connect to your Mac the properly formatted hard drive or flash drive you want to use for your bootable Mountain Lion installer. Drag the Mac OS X Install ESD icon into the Source field on the right (if it isn’t already there).

Once you’ve downloaded it from the developer’s website—or, if you already had it, once you’ve checked to make sure you’ve got the latest version—follow these steps: As of version 10.7.4 of the Lion installer, and continuing with the Mountain Lion installer, you must use the mounted Mac OS X Install ESD volume or you’ll get an error at the end of the restore procedure, and the newly created bootable drive may not function properly.)You can use Disk Utility’s Restore screen to create a bootable flash drive or hard drive.Using Carbon Copy Cloner Version 3.5 or later of this excellent clone-backup utility includes a special feature for creating a bootable install drive.
