VoodooHDA - problemas comuns

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.

Não sei, aqui as configurações permanecem após reiniciar

Tente ativar a chave Vectorize, talvez não precise reduzir a frequência.

Predatux · February 28, 2012

Ok, a ver si lo saco.

Un saludo

Eu to com um probleminha aqui, não sei exatamente se é com a kext ou o prefpane.

Eu percebi que botando o volume do mic e line in no minimo pelo prefpane, todo o ruído some das saídas.

Até aí tudo certo. O problema é que quando eu reinicio, essas configurações se perdem, e eu tenho que ajustar tudo de novo.

O que pode ser feito pra que isso fique salvo, ou então como faço pra que o Voodoo não detecte o microfone e line in (e torcer pra que assim não haja ruído)?

Cassio · March 12, 2012

Você pode definir os valores no Info.plist (MixerValues) ou usar o app VoodooHdaSettingsLoader nos itens de início de sessão.

Talvez ajustando iGain ou Monitor você tenha as entradas funcionando e sem ruídos, veja sobre microfonia no primeiro post.

Para desligar as entradas você pode ajustar o PinDefault desses nodes (NodesToPatch)

Coloquei o loader, tomara que funcione. Valeu!

Ola,minha duvida acredito seja bem simples,eu quero saber como descubro DeviceID e o VendorID da saida HDMI.

Citação:

a saida HDMI existe,o grande caso é o seguinte é necesssario estar em uso ou plugada para ser detectada ou não...oque segue logo a baixo é oque tem junto

Não entendi a relação.

Acredito que a saída HDMI esteja ligada ao mesmo dispositivo que as saídas analógicas, não tem dois dispositivos PCI de áudio.

@Cassio

Não entendi a relação.

Acredito que a saída HDMI esteja ligada ao mesmo dispositivo que as saídas analógicas, não tem dois dispositivos PCI de áudio.

Eu que entendi mal suas palavras,então esta tudo no mesmo deviceID e VendorID [8086:1c20]

Solução: use a solução 2 para o problema de kernel panic. Se quiser usar as duas placas, crie uma entrada para cada uma em IOKitPersonalities.

1 entrada

<key>IOPCIPrimaryMatch</key>
        <string>0x1c208086</string>

como seria a entrada HDMI nesse caso...eu to confuso com isso,acredito que no meu caso seja só uma placa e só uma entrada no IOKitPersonalities.

Nesse caso eu não conheço solução pro áudio HDMI.

Esta parte é inútil

Como falei antes, esse é um ID de codec e não um ID PCI, o "match" nunca vai acontecer.

@Cassio

Eu puz o mesmo DeviceID e VendorID nas duas partes e ele carregou denovo no boot,e no configurações de audio e midia ele mostra a saida com 16 canais,AC3 (8) e output stream mais(8),segue as imagens ai,não vou consseguir testar,não tenho hardware.

Cassio · March 21, 2012

Se não tem hardware, por que se preocupar com isso?

Faz alguma diferença botar o mesmo ID duas vezes ou uma vez só?

Crosx86 · March 21, 2012

@Cassio

Estou penssando em comprar o cabos e a tv com entrada(hdmi).

Mais voçe tem razão,na veradade eu poderia deixar pra hora certa.

Faz diferença,sem a segunda parte não carrega o output no boot em -v.

Eu notei somente essa diferença,no boot -v

Não entendo o que você quer dizer com "carrega o output".

Faz alguma diferença prática, nas entradas e saídas disponíveis?

Não entendo o que você quer dizer com "carrega o output".

ele escreve algumas linhas no boot em -v,algo como: Enebling Digital output Device e ai escreve os minimos e maximos(min41.100,0hz e max192000,0hz) umas 5 linhas no boot.

Faz alguma diferença prática, nas entradas e saídas disponíveis?

Eu não percebi,mais posso testar.

Edit:

Testado,ele escreveu no boot mesmo sem a segunda parte(HDMI),oque faz ele escrever no boot em -v é talvez a modificação do plist(SoundCard),sera..

nenhuma modificação no Midi.

Pra finalizar eu fiz o teste com a primeira parte do plist(SoundCard)

		<key>VoodooHDAEnableVolumeChangeFix</key>
		<false/>
		<key>VoodooHDAVerboseLevel</key>

	</dict>

sem e com a segunda parte(HDMI)

		<false/>
		<key>VoodooHDAEnableVolumeChangeFix</key>
		<false/>
		<key>VoodooHDAVerboseLevel</key>
		<integer>1</integer>
	</dict>

Conclusão ele escreve no boot de qualquer maneira,só que quando uso somente a primeira parte tenho alguns KPS antes de ver a tela,segui a imagem doque ele escreve.
