OS is recognizing the Intel HD 4000 card, but everytime it attempts to load the kexts, it fails... I had to remove all the AppleIntelHD* kexts to another folder in order to boot the notebook. But know I dont have video acceleration...

It`s a problem with the kexts or I need a DSDT.aml ?

hello

are u sure that is ur problem ? u have glitches in ur lcd ?

u must use the right ig-platform-id for the hd 4000

usually

platform-id 3 .. resolution 1366x768

platform-id 4 .. bigger resolution .. also use dual link

http://clover-wiki.zetam.org/Configuration/Graphics#ig-platform-id

and use a proper smbios

good hack

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.

Yes, I have read, but didnt understand completely... and since it worked I didnt remove the AzulFB key.

I was reading the topic you mentioned and except for the DSDT patch (which I have no idea how it works), everything is fine.

I think gonna try a fresh install and changes some things, see if it works.

I`ll be back.

[mrgtrader]

Yes, I`m back!

I tried almost everything, including DSDT patches... i was already downloading the Yosemite to try it, see if it works when I found this guide:

http://rampagedev.wordpress.com/more-guides/intel-hd-graphics-guide/

First I only have tried the 3 and 4 IDs... but after seeing this guide I tried the 1 and it worked! Really AWESOME!

I don`t know why, but the first guide I read showed me that the 1 ID was no good for me... for this reason I have even tried.

Obs.: And I have changed too my SMBios, according to this new guide.
