Make Mountain Lion Usb On Windows Download A New

If you need to install multiple copies on a few computers, or even prefer not to have to download a new copy every time you have to install the Mac OS.

And from what Ive experienced, installing from a USB Flash drive is faster than installing via downloading a new copy from the Mac App Store or even from DVD.

There are just certain parts that need extra attention however, I will highlight these areas.

Once Mountain Lion has been downloaded, youll be able to find it in your Applications folder.

Go to your Applications folder and locate the Install OS X Mountain Lion app.

Once opened therell be a folder called Contents, open it, and finally open the SharedSupport folder.

Inside this folder there should be 2 files, one called InstallESD.dmg and the other OSInstall.mpkg, copy the InstallESD.dmg to the Desktop.

This will be the file that well be using to create the bootable disk image onto the USB Flash drive.

Nowadays USB Flash drive are really cheap and can be purchased at almost any electronics store (the Flash drive I use is 16GB and only cost 15).

Plug it into your Mac, and launch Disk Utility (located in ApplicationsUtilities).

Under the selection for Format: select Mac OS Extended (Journaled), and name it anything youd like.

It would probably would be best however to make it something recognizable like Mac Install or Mountain Lion Installer.

Up to you though.

Then simply press the Erase button on the bottom right when done.

The USB Flash drive will then start to format; in most cases it takes less than a minute.

Heres an affiliate link to a 16GB USB drive that comes already properly formatted for the purpose of installing Mac OS X.

In Disk Utility select the partition that was just formatted and click the restore tab.

Make sure to select the partition that youve created and not the drive itself.

To elaborate, as you can see in the screenshot, Ive selected the partition I named Mac OS X Install ESD, not the drive itself.

One is to go to System Preferences - Startup Disk - and select the USB drive.

This will load up the Mac OS X Mountain Lion installer as soon as you restart your computer.

The other method is to simply hold down the Options key on the keyboard when your Mac is just turning on after being shutdownrestarted.
