After installing OS X, you’ll have vanilla files which won’t work as expected with non-Apple hardware. Multibeast will replace some system kexts and will apply some patches and fixes to make your system fully working again. It’s a simple tool that allows you to put the OS X installer on the USB drive and boot from it. Once downloaded, it will try to install: let it do that, it’s extracting some files we’ll need later! After that, your computer will reboot on Lion. That’s simple, just open the App Store, reach the Updates tab and you’ll find the option to upgrade there. Installing from USB is easier, faster and cheaper (you don’t have to buy a DL-DVD for a one-time use).

You’ll need a spare USB drive (at least 8Gb). This guide will show you how I upgraded my iAtkos ML2 installation to 10.9 Mavericks using vanilla system files.

It prepares for installation, then reboots on your old system as usual. But if you try to install it, you’ll find out that it just doesn’t work. So, even if you’re running an hackintosh, you can download it from the App Store and avoid looking for it somewhere else. That means you can get it from the App Store and install it, as long as you already have OS X installed. OS X Mavericks has just been released… for free.
