radeon 7870 partially working, help needed

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.

PS. posted this on other forums too so I am "reaching out"

Hi guys! I have some issues these past days when it comes to my build. I can successfully start osx with 7870 but I have no acceleration. Here is a screenshot with info from system to tell you a bit more. Sometimes when I look at info it says 7870 and sometimes it says 7XXXX. I try to combine graphicsenabler with both yes and no, tried some different aticonfig like hamachi etc.

Do you guys have any pointers what to do next? I read somewhere about must having DSDT inject etc. I have never used DSDT before. The system works good except graphics.

I have theses specs:

ASROCK z77 pro

I5-3570k 3,4GHz

GIGABYTE 7870 OC 2Gb editition

pixellegolas · July 4, 2013

Tried Aji, Hamachi, duckweed and now Dashikawa. Mostly I dont see 7870 anymore but 7XXX instead. Will try a reboot with graphicsenabler=no once again

artur-pt · July 4, 2013

hello

i don't see

amdradeon4000 ?

or amdradeonaccelerator ?

what mac os x are u using ?

take a good read here

http://Olarila.com/forum/viewtopic.php?f=28&t=736

must understand how it works..

and for that must read and googling

good hack

pixellegolas · July 4, 2013

I am using 10.8.4 as you can see in picture. I have upgraded from 10.8.2 to 10.8.3 and then 10.8.4, but at both times I had some errors. Finally I copied the kext files to extensions

Will read alittle on that thread you posted now

Mirone · July 4, 2013

@Pixellegolas

send me a copy of your DSDT + ioreg untouched.

pixellegolas · July 4, 2013

Hi! That's the thing, I have never used DSDT so I need to make one. Will check some guides about it.

Mirone · July 4, 2013

run this app and send me the generated folder on your desktop.

So here are the kexts. Could this be the bad boys making all the frustration?

PS. link to my files on previous page

Edit: So I saw that my Id was not present in ATIFramebuffer.kext so I found a new kext online and stuffed it in there instead. Also chose aticonfig=Chutoro that I think I saw somewhere is the correct one.

It booted into black osx and could not sleeptrick out of it. Had to restart and choose GraphicsEnabler=no to boot again

pixellegolas · July 4, 2013

Ok, I see now that I dont even have AMDframebuffer. I have ATIframebuffer though. Could someone post the AMDframebuffer.kext?

Mirone · July 4, 2013

@pixellegolas

Try this DSDT.aml

The Pitcairn Family is your Graphics Card.

Boot with GraphicsEnabler=No

get back to me with results.

pixellegolas · July 4, 2013

Should I skip the aticonfig?

Mirone · July 4, 2013

Should I skip the aticonfig?

Yeah!

try this.

pixellegolas · July 4, 2013

Booting up with GraphicsEnabler=no and no aticonfig gives me same result as always. But now card is named 7xxx instead of 7870 again.

Could it be bios settings? Kext errors? I read somewhere about using hdmi or dvi port could do the difference. Stating ports etc. Trying all I can here

PS. By the way, I used the dsdt by choosing it in the chameleon wizard. I have it on desktop still. Do I need to use it in some other way? I see in chameleon wizard I can also Patch the dsdt etc

you have to put the dsdt the root system or the extra folder.

Mirone · July 4, 2013

@pixellegoas

try this:DSDT.zip

Boot with GraphicsEnabler=No

pixellegolas · July 5, 2013

No change. Now I saw in bdmesg that it loaded the dsdt and I chose graphicsenabler=no

I do however notice an error that occurs just before the white screen:

kx(com.apple.AMDRadeonAccelerator)
Can't load kext com.apple.AMDRadeonAccelerator - link failed
Failed to load executable for kext com.apple.AMDRadeonAccelerator
kext com.apple.AMDRadeonAccelerator failed to load (8xdc000016)

stuff in parenthesis is fussy so dont know what it really says

further down:

ATY_init: Starting
ATY_init: Checkingg dev-id 6818
ATY_init: Card 0x6818 was posted
ATY_init: Quitting for card 0x6818

Mirone · July 5, 2013

@pixellegolas

in a terminal type:

sudo ketcache -prelinked-kernel

then repair the permissions and rebuild caches using kextwizard.
