Ok, thanks for the answer...
I am already using platform id 3... But I am using chameleon, not clover... like this:
GraphicsEnabler
Yes
IGPEnabler
Yes
InjectIntel-ig
03006601
IntelCapriFB
3
IntelAzulFB
3
Graphics Mode
1366x768x32
And this settings works, it shows Intel HD 4000 on System Information app, with another set of keys it doesn`t.
And my SMBios I have set according to a post saying that is the best for my processor:
SMbiosdate
05/10/12
SMbiosvendor
Apple Inc.
SMbiosversion
MBA51.88Z.00EF.B00.1205221442
SMboardproduct
Mac-2E6FAB96566FE58C
SMfamily
MacBook Air
SMmanufacturer
Apple Inc.
SMproductname
MacBookAir5,2
SMserial
C02LG674DRVC
SMsystemversion
1.0
The problem is that the system doesn`t boot up since installation... only in safe mode OR if I remove the AppleIntelHD* kexts. I have to return this kexts, but how do I do that without ruining my system?
I was able to boot the system one time with all the kexts, but that time I have installed a patched AppleIntelCpuPowerManagement... however the system showed me Kernel Panic after a few minutes so I removed it and now I am using NullCpuPowerManagement... it could be it ?
In another topic someone suggested to use an DSDT.aml but I have no idea how.
