How to patch AppleHDA

Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

Mirone here is my DSDT. Hope it will be correct this time.

Thanks

whityini · October 30, 2013

Mirone good news!!

I have removed the option NCPI=0x3000 from org.chameleon.Boot.plist and now the sound works correctly with your AppleHDA.kext.

It seem the DSDT is correct.

Thanks again for your help.

install kext+DSDT, repair permissions rebuild caches using kextwizard.

Hey there,

I successfully installed Mavericks on my Acer 4820T but the audio is not working.

I believe it is an ALC269. Is there a kext out there already working for this sound card (VoodooHDA) or do I need to patch my AppleHDA?

Thanks for the help

Mirone · December 8, 2013

try this: ALC269

actrite · December 8, 2013

I installed your kext with Kext Drop and still no sound. Do I need to edit my DSDT with the info from the README file? I currently don't have a DSDT for my laptop/motherboard. Can you assist me in creating one/downloading a pre-existing DSDT file?

Thanks

Hello

You can try install VoodooHDA 2.8.4: www.projectosx.com/forum/index.php?showtopic=355

Remeber, remove AppleHDA or install AppleHDADisabler if you want install Voodoo...

Hint: Install with Chameleon Wizard and update cache.

If you don't want use voodoo... send your ioreg+DSDT to Mirone.

actrite · December 9, 2013

Thanks, I'm going to try that method right now, but just in case I attached my ioreg and dsdt file. I'm willing to do anything to get this working!

VoodooHDA 2.8.4 works! Thanks a lot

Now If I could only get my video, webcam and wifi (AR9285) working

Doggynub · December 11, 2013

about the part in the applehdacontroller with the device and audio id which one should I put there?!

I have in System info app it shows : DevId = 1c20 - VendId = 8086

but in the codec_dump it shows vendor id = 0x10ec0665

Which one should I put there?

noyfb · January 24, 2014

21-16-3-->Speaker

20-15-2-->Phone

7-36-25-->Mic Int.

8-35-24-->Mic Ext.

Note: For notebooks is necessary to add a codecverbs to the EAPD.

in your case would 01570C02.

How did you get to the conclusion that his codecverd was 01570C02 by just looking at his graph?

Aren't codecverbs 4 x 8 alpha numeric sequences?

Mirone · January 25, 2014

This is a value for EAPD.

noyfb · January 29, 2014

I understand it's for EAPD Detect.

I can not figure out how you got that number. Where did you pull it out from?

How did you build that sequence?

Mirone · January 29, 2014

Mirone the kext not worked in 10.8.5 and 10.9

My files of audio are on link: https://drive.google.com/folderview?id=0ByWfoqaIn-fCX2lsUGctUjNrQWc&usp=sharing

Baoren · March 1, 2014

Hi there, my 1st post,

if possible I'd need some help to complete the patch I am trying to do on an AppleHDA.kext for my laptop (G74sx). It should have an ALC269VB, but i think it has a peculiar version of it, so standard kext patched don't work. I used and old version I found of AppleHDA.kext which worked fine till now (with some problems time by time), but is not working anymore in 10.9.2.

I followed all the 1st steps. I extracted codec_dump.txt, I converted to hexadecimals, I created the svg from these files, and so the verbs. I modified the info.plist from the 2 kexts inside the plugin folders.

My doubts start at this point.

1St of all, in the folder AppleHDA.kext/Contents/Resources, from an original AppleHDA.kext from 10.9.2, there are these folders:

English.lproj

Japanese.lproj

ko.lproj

zh_CN.lproj

zh_TW.lproj

And these files:

DefaultAudioLevels.plist

layout90.xml.zlib

layout92.xml.zlib

layout94.xml.zlib

layout120.xml.zlib

No trace of layout12.xml.zlib or platforms.xlm.zlib. But I see in other AppleHDA.kext already patched these files are present. So my 1st query is this: where are these files?

Anyway, I tryed to understand the structures of these files taken from other kext already patched.

It seems quite easy to modify the layout. But platforms.xml seems quite troubled to me. I don't understand enough the SVG file I created from codec dump. Especially, I don't understand these things:

the difference between dot lines and normal lines

the difference between grey and blue lines

which of the nodes I should check, considering that they seem to be more than I need

And I don't understand as well the structure that pathmap must follow. Without some suggestion it will take me a life to understand it properly.

I didn't try to patch the AppleHDA inside MacOS folder, but now I want to solve these other steps, if I find any problem at that point I'll post again.

I may need to review also my DSDT, but I think I can figure it out by myself. And if I won't, I'll ask.

I am open to any suggestion. I will attach the files I extracted so you can give it a look. Also, I'll add a converted version in PNG of the codec_dump_dec.txt.svg.

Thanks for any help

Speaker = 27-13-3

Headphones = 33-12-2

Ext. Mic = 9-34-24

Int. Mic = 8-35-25

In his pinconfigs you will need a EAPD

to be 01470c02.

The best way for you to see this is with a cmparando

kext already corrected, take it as an example.

Hi,

i have a HP G72 from my working colleague here and i try to patch the ALC270, because all the kexts floating around do not work for me.

I have tried layout 12 and 28.

Only headphone is working with the patched kext. With voodooHDA i get full sound.

Inject via clover, no DSDT injection.

Please can you take a look or do you have some ideas?

Thank you

koreandokdo · June 14, 2015

A noob question, Sorry,

As weird as it is, I can not find any .xml files of whatsoever in the Resource folder!!

Am i even looking in the right place ? By Resource folder does it mean in AppleHDA.kext > Contents > Resource?

If not, should i add or create the said .xml files there?

By the way I am on 10.6.3. (Yeah, outdated i know )
