With that in mind, it makes sense to use the downloaded installation file to create a separate and independent bootable USB/SD Card/DVD drive. Or if they want to install it on multiple machines without having to download it from Mac App Store again and again, or in case they want to install the Mountain Lion as a fresh install. The lack of a physical installation source causes some people to have flutters incase something actually goes wrong with their Mac, and they can’t get access to the downloaded installer on the machine.


With Mountain Lion being initially available and distributed through the Mac App Store, it obviously means that it doesn’t come with an installation DVD nor a USB. The fact that Apple’s new OS is now available is obviously a positive thing, but once again the fact that it only comes as a digital download has caused a few people to raise their eyebrows at the company’s chosen method of distribution. For more on Mountain Lion, be sure to read the official Cult of Mac review.With Apple finally releasing OS X Mountain Lion via the Mac App Store, users can quickly open the store up on their Macs and get their hands on the latest player in the desktop operating system game. If you’d rather install Mountain Lion without a bootable copy and keep your setup the way it is, refer to our general tutorial. Choose your Mac’s hard drive and begin installing Mountain Lion.īy following those steps, your Mac will be restored to Apple’s stock setup and all of your personal files will be gone. Once your Mac’s hard drive is erased, quit Disk Utility and go back into the Mountain Lion installer.

(Make sure you have a backup first, just in case.) From the erase tab, choose “Mac OS Extended (Journaled)” and wipe your drive.
