One of the most convenient aspects of the newly released OS X Mavericks is that it is available through the Mac App Store as a simple update for Mac users. That means after you download it all you have to do is
follow some simple instructions
to install it without much trouble.
However, some users really prefer to do a clean install in these cases due to the benefits it offers, such as eliminating system errors and unnecessary files that can be moved to New OS if we just update it for example.
If you’re one of those Mac users, here’s a simple guide to doing a clean install of OS X Mavericks. Needless to say, you should back up all your important data somewhere outside of your Mac.
Start.
Create a Bootable USB Drive
To install OS X Mavericks from scratch, you’ll first need to create an installation USB that you’ll use to boot your Mac. The process used to be cumbersome before, but with the help of a smart Terminal command, it’s become really simple now.
First, make sure to download the Mavericks installer app from the Mac App Store. Once done, you should have an app called ‘Install OS X Mavericks’ in your Applications folder.
Now get a USB with at least 8 GB of free space and make sure it is named Untitled and formatted in Mac OS Extended (Journaled) format using Disk Utility (this is how you can do it) ). Once you have it, plug it into your Mac.
When ready, open the Terminal application and enter the following command exactly like here:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install\ OS\ X\ Mavericks.app –nointeraction
This will automatically create an OS X Mavericks bootable USB in 20 minute intervals. For reference, here’s what you’ll see on the Terminal window throughout the process until it’s done.
Erasing disk: 0%… 10%… 20%…Copying installer file to disk…Copy complete.

Finished.
Install OS X Mavericks
Turn off your Mac and plug in the fresh install USB into it. Then turn it on and immediately press and hold the Option/Alt key on your keyboard. This will bring up the Startup Manager with all the drives on your Mac. Select your newly created drive, it will be orange.
Now, on the first installation screen, before installing OS X Mavericks, on the menu bar at the top of the screen, click utilities and choose Disk Utility from the available options.
On Disk Utility, select your Mac’s hard drive (as shown below) and on Erase select tab Mac OS Extended (Journaled) Format. Then give your hard drive a name and then click Erase.
After a few minutes, your hard drive will be erased and you will be returned to the ‘Install OS X’ screen. From there, just click Continue and follow the process until OS X Mavericks is completely installed just like it was on a new Mac.
Note: As an added bonus, this method will also install a recovery partition on your Mac.
