VoodooHDA is a simple kext that enables audio on hackintoshes. I tested it on OS X 10.9 Mavericks and 10.8 Mountain Lion (with iATKOS ML / ML2) and it just works. Of course it depends on your audio card, but as far as I know, it works on almost every card.
The problem is that VoodooHDA kext sometimes gives kernel panic. They seems to be totally random and sometimes disappear on reboot, sometimes not.
However, here’s the fix: VoodooHDA kext with kernel panic issue fix!
Voodoo Battery is mainly known for two reasons: it works on almost any system, and it has bugs. However, this is the simplest way to get a battery meter on an hackintosh (tested on Mavericks and iAtkos ML) and bugs can be worked around easily.
OS X Mavericks has just been released… for free. That means you can get it from the App Store and install it, as long as you already have OS X installed. So, even if you’re running an hackintosh, you can download it from the App Store and avoid looking for it somewhere else. But if you try to install it, you’ll find out that it just doesn’t work. It prepares for installation, then reboots on your old system as usual.
This guide will show you how I upgraded my iAtkos ML2 installation to 10.9 Mavericks using vanilla system files. You’ll need a spare USB drive (at least 8Gb). Installing from USB is easier, faster and cheaper (you don’t have to buy a DL-DVD for a one-time use).
