hi everybody
I've got an alienware m17x r4
chipset : intel hm 77
integrated graphics : intel hd 4000
gpu : amd hd7970m
cpu : i7 3630qm (ivy bridge)
i'm on mountain lion 10.8.2
What works : intel hd 4000 but only when i'm plugged in with an hdmi otherwise my integrated screen remains black
the sound works but i can't adjust the volume
the wifi doesn't work (i have an intel centrino N2230)
the sound via hdmi doesn't work aswell
amd hd 7970m doesn't work
usb 3.0 doest work but i can get the usb works by disabling the xhci in the bios.
Could anybody help me and i dont have a dsdt file in my osx,
Thanks in advance
