Motherboard: GA-Z77-D3H Processor: Intelcore I5 3570K MemoryD3 16GB Graphics: For the moment HD4000 tested with XFX Radeon 5770 but got som graphical glitches in the black tones. Everything was pretty easy, just bought the Mountain lion from app store. Used unibeast to install. Had to install the drivers for the networkcard and change the resolution for hd4000. My only problem now is the sound... lot of people has problem withVIA VT2021 found a solution for lion but this dont work for the mountain lion. Does anyone has a solution for this except change the soundcard?
