To let you all know. After update to 10.8.3 the following changes were needed.
1) In AppleInterFramebufferCapri.kext change connector string for AAPL,ig-platform-id: 01660003 (if that's what u use)
from
@0, 05 03 00 00 02 00 00 00 03 00 00 00 // LVDS @1, 02 05 00 00 00 08 00 00 06 00 00 00 // DisplayPort @2, 03 04 00 00 00 04 00 00 81 00 00 00 // DisplayPort @3, 04 06 00 00 00 04 00 00 81 00 00 00 // DisplayPort
to
@0, 05 03 00 00 02 00 00 00 03 02 00 00 // LVDS @1, 02 05 00 00 00 08 00 00 06 00 00 00 // DisplayPort @2, 03 04 00 00 00 04 00 00 81 00 00 00 // DisplayPort @3, 04 06 00 00 00 04 00 00 81 00 00 00 // DisplayPort
Otherwise screen won't lit. Alternatively use patched one from 10.8.2
Some other kexts were overwritten So I had to return the patched ones.
AppleACPIPlatform.kext (for battery)
IOBluetoothFamily.kext
IOAudioFamily.kext (needed by VoodooHDA?)
IONetworkingFamily.kext no longer needs patching as it includes BCM5722D.kext with pci144e,1681 it seems
As for WiFi card (I use Atheros AR5B95) I patched IO80211Family.kext again by adding its id
into match list of info.plist inside the AirPortAtheros40.kext (WiFi)
Let me know how it goes in your case.
BTW. Still trying to enable HDMI.
I am almost sure that it is the 4th connector string i.e. @3, 04 06 00 00 00 04 00 00 81 00 00 00 // DisplayPort
It senses hotplug and it worked on my HP Probook but some numbers have yet to be adjusted.
