Installing OS X Mountain Lion

As previously stated, as of this writing OS X Mountain Lion can only be installed via the Mac App Store. To download and install OS X Mountain Lion, all you need to do is open up the Mac App Store and click on OS X Mountain Lion, which is currently featured at the top of the Mac App Store screen.

It took about an hour for OS X Mountain Lion to download onto my Mac. You will be prompted to begin the installation process once the download has completed.

As OS X Mountain Lion begins to install, you’ll be asked some very basic questions and you’ll be prompted to accept the EULA. You’ll also be asked to enter your password in order to allow OS X Mountain Lion to be installed on your Mac’s hard drive.

Your Mac will reboot and you’ll be brought to a screen labeled Install Mac OS X. There’s nothing to do at this point except sit back and wait while OS X Mountain Lion is installed on your Mac’s hard drive. The actual OS X Mountain Lion installation only took about half an hour to complete.

After OS X Mountain Lion has been installed on your computer you will be prompted to enter your Apple ID.

If you choose to enter your Apple ID you’ll be prompted to setup iCloud. Setting up iCloud and cloud based personal file storage is beyond the scope of this article, you may setup iCloud on your own providing that you are comfortable with storing your documents in the cloud.

All in all setting up OS X Mountain Lion was a breeze. I did have to upgrade to the newest version of Little Snitch after upgrading to Mountain Lion, but that is to be expected with antivirus and firewall software.
