Hello Shinji3rd!
So I installed my hackintosh with your guide, and almost everything is working!
First of all, I already had a dw1560 wifi/bt card so I installed it and I have wifi and bt working fine.
So comes my first question: you installed NullEthernet because you don't have internal wifi or ethernet hardware, right? I didn't install it.
Then AppleHDA Patcher method didn't work for me, so I went with VoodooHDA 2.8.8 pkg. And it works (I haven't test audio through HDMI because my external monitor don't have audio).
The one thing I struggle with is the brightness fn keys. I can control brightness from Prefs>Monitors, but not with fn keys, any idea?
Thanks again for this great guide!
