Q: What is a Hackintosh?

A Hackintosh is a non-Apple computer that runs macOS using compatible hardware and custom bootloaders such as OpenCore or Clover.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple's macOS license agreement. It is generally used for educational and experimental purposes.

Q: What hardware is best for Hackintosh?

Intel CPUs with compatible chipsets and supported AMD GPUs are typically best for Hackintosh. Hardware compatibility is critical for stability and performance.

Q: What is OpenCore in Hackintosh?

OpenCore is a modern bootloader used to boot macOS on non-Apple hardware. It provides better compatibility, security, and system stability than older bootloaders.

Q: Can Hackintosh be updated like a real Mac?

Hackintosh systems can be updated, but updates should be done carefully. Bootloader, kexts, and configuration files often need updates before installing new macOS versions.

Q: Is Hackintosh suitable for professional work?

A properly configured Hackintosh can be stable enough for professional tasks such as software development, audio production, and video editing, depending on hardware compatibility.

Q: Does Hackintosh support Intel and AMD processors?

Hackintosh supports both Intel and AMD processors, although Intel systems generally offer broader compatibility and easier configuration.

Q: Can macOS run faster on Hackintosh than on a Mac?

In some cases, high-end Hackintosh hardware can outperform older Macs, but performance depends on hardware choice, configuration quality, and macOS compatibility.

Hello again, Mirone.

For if necessary I attach the "codec dump" my ALC268 extracted from Linux.

Thank you.

Hello Mirone.

Thanks for your feedback.

The file you sent me works, but only half. Consider:

positive:

1. Now the sound icon in the menu bar is enabled and the volume control works.

2. In Preferences detects the device and controls work.

3. System Information shows all the components of the device correctly.

4. The internal microphone works.

negative:

1. There is no sound from the internal speaker. But if you hear when you connect headphones (although the sound is poor).

2. No Preferences detects change internal to external devices.

3. No chance of noise reduction for the microphone ..

4. Multiple kernel error messages like "Sound assertion in AppleHDAWidget at line ..."

Can you help to solve these problems? I've been trying for several days but nothing works.

A greeting.

I will calmly analyze later and send you another kext.

Hello, again, Mirone.

I further investigated, starting from the HDA kext who sent me and I got everything to work ok.

I have done the following:

1.I reconfigured Platforms.xml and layout12.xml from AppleHDAPlatformDriver.kext of 1.7.4 version of AppleHDA.kext that had been using since Snow.

2. In info.list (configdata) of AppleHDAHardwareConfigDriver.kext, I have also used the 1.7.4 version

With these changes everything works correctly.

Only slight problem not solved:

Every 50 seconds, exactly, the kernel delivers 4 times the error messages "Sound assertion in AppleHDAWidget at line 2122", that's all.

Now I'm researching, using your guide, and I'm trying to patch AppleHDA.kext native ML, ie from version 2.3.0.

I have not achieved anything. No I do wrong, or maybe the settings need to be different.

I'm patching from ADI 1984B. Is that correct? or in ML must use ADI 1984 or ALC 885? Always from Layout ID 12?, as it is in DSDT?

My weak point of the whole process is the Platforms.xml, then I lose. Maybe that's why no work.

I can help achieve this, if possible?

Thank you very much for your cooperation.

Boa tarde... Obrigado por se dispor a ajudar. Uso o ML 10.8.3.

ADI1984b correct, you can use other layouts,

pathmaps and follow the examples of kext I sent you.

i tried running this script but it gave me this error

cd ~ / Desktop && mkdir CodecDump && c is in / proc / asound / card * / codec # *;'s f = "$ {c / \ / * card / card};" cat "$ c"> CodecDump / $ { f / / \ / / -}. txt; && zip-r done CodecDump.zip CodecDump

c: command not found

than i figured it out that google translate fuxed it , so i copied the script again from its original form than it worked and gave me the zip file but i think my audio device is not in there and only the HDMI is available, so please look in the attached file of codec_dump

--------

i tried to run that .sh script which is posted as an attachment in that thread but it didn't gave me any output and just showed me a blinking cursor........i left it for around half an hour in that way but still the same blinking cursor.

these are your video card's HDMI audio, Try again I need your codec_dump ALC898.

Run this in the terminal:

cd ~/Desktop && mkdir CodecDump && for c in /proc/asound/card*/codec#*; do f="${c/\/*card/card}"; cat "$c" > CodecDump/${f//\//-}.txt; done && zip -r CodecDump.zip CodecDump

use last version of Ubuntu: http://www.ubuntu.com/download

i think linux didn't detected my audio device thats why it happened......i have tried it so many times and the same result came, so i used darwin dump in OS X
