Hey, sorry about the outdated kexts but i think by now everyone should have learned how to patch your AMD6000Controller.kext, it is a simple task and there are instructions here how to do it yourself. There is even better way now with Clover, no need for DSDT patches etc, you can do everything with Clover, kext patching, EDID injection etc.

but here it is one last time:

1. Copy AMD6000Controller.kext to your Desktop

2. OPen HexEdit and go to File > Open and chose the AMD6000Controller binary inside the kext

3. Go to Find>Find and Replace

 

post-423012-0-29324300-1402912621_thumb.png

 

    In the "Find" field paste this

000400000403000000010000120401050008000004020000000100001102040310000000100000000001000000000002

    In the "Replace with" field paste this

020000004000000009010000100100030008000000020000000100001102010110000000100000000001000000000205

or this if you are using some sort of custom EDID injection (DSDT or DisplayMergeNUB.kext) to fix the gradients issue

020000004000000009010000100000030008000000020000000100001102010110000000100000000001000000000205

4. Click "Find next"

5. You will get this in HexEdit window

6. Click Replace and you will get this, the new patched framebuffer

 

post-423012-0-40167400-1402913390_thumb.png

7. Go to File>Save

You just patched your kext.

For first, thanks for your consideration.

 

I did the patch to the 10.9.1 and 10.9.3 clean kexts and see a kinda weirdo thing that is 10.9.1 is worked as before what you share and 10.9.3 is gave me a speedy flickering screen.

 

So that's why i thought maybe you did one more thing so the reason of my last post is understanding if there is more thing i can do. so that's why i asked again.

 

For last, i know if i search more i'll discover more. But one of the reason of forum creation is sharing knowledge and helping to non-geek guys in a suitable way.

 

Have a good day. :angel:

Hello everyone,

I recently installed OSX 10.9.0 (Niresh) I too have problem with graphics. It only shows 3MB vram.  Although it is a Radeon 6550m, my device id  is inside  AMD5000Controller.kext and AMDX3000.kext.  I read the opening page and properly understand patching and stuff. Do I need to the HEX thing with AMD5000Controller.kext, instead of 6000?Please help me!  :(

 

#Update 8/4/2014 I installed clover bootloader and using Clover configurator I injected my edid and set LoadVBios=Yes, PatchVBios=Yes, InjectATI=Yes, set ATIPort=3 and I saved the .plist file. When started my computer nothing happened. It's like my hackintosh doesn't care I installed Clover on top of Chameleon. Then I made clover usb using BDUtility and booted. Then, while booting hackintosh showed non-flat (just like in the back iphone) apple. When it booted everything looked awesome. I thought, it worked. When I checked the resolution was native (1600*900) :), but the vram went from 3 MB to 5mb. And Kext is loaded. I tried to make sure it was just reading it wrong. When I open apps (safari) it flickers a lot. I tried some Frame Buffers which people claim are working. Nothing happened.

Hi guys!

I have 7970m, I know this is not my topik so I did this one:

http://www.insanelymac.com/forum/topic/300160-hd7970m-and-clevo-p370em/

I have strange colors like edex96, like in post, but my EDID does not need changings.

I've read post #557 by freeuser16 but mine basic parameters are:

90 26 15 78 02 ...

Any advise?

Thanks!

Hi all, I have an Acer Aspire 7750G with a 1GB 6650M running Mavericks at the moment without any acceleration. I never bothered to use this guide as it looked waaay out of my scope of knowledge. Re-reading through it though, it appears to me that if I use method #2, I don't need to touch my DSDT at all, and the only thing that needs to be touched is the AMD6000Controller.kext. I just patch that, drop it in S/L/E, then boot with GraphicsEnabler=Yes? If that's the case, can someone please provide me with the instructions for a 1GB 6650M?

Thanks!

Hi 

Trucker if you have time would patch me this clean  kext (from yosemite (Not DP)). I don't which patch you used exactly,  here is my vbios, if you have time please write here what patch you used and what numbers you have changed in hexedit.
like you did last time i need lvds and hdmi 
Thank you again

If you have an Ivy CPU with a 6-series board (rare) or a Sandy CPU with a 7-series board (not as rare), you'll probably have difficulty reaching the installer even if you provide the correct "ig-platform-id" or patch the DSDT. The graphics drivers are dependent on the driver for the Intel MEI device. Apple put the MEI driver for the 6-series boards is in the same kext as the HD3000 controller, and the MEI driver for the 7-series boards in the kext for HD4000 controller. This is why it is impossible to load the framebuffer from the HD4000 controller, using the MEI for a 7-series board, when you have a HD3000 controller on a 7-series board. Similarly, it is not possible to load the framebuffer from the HD3000 controller, using the MEI for a 6-series board, when you have a HD4000 controller on a 6-series board. You can fix the IMEI with the Clover EFI bootloader and patch the AMD Controller/Framebuffer in some cases. Assuming that you have both a HD4000 and Radeon HD controller, you might just consider disabling the discrete GPU capabilities completely. As for the Radeon HD, it is always a "shot in the dark" getting them to run properly. Even when you decode the VBIOS, and patch the right framebuffer in the AMDXXXXController, there are several different chipsets in the same series. If you get the right Intel Management Engine, the right framebuffer, and the right ASIC chipset architecture you'll have full QE. Forcing your GPU to run a different architecture, and having an incomplete EDID, will give you graphical anomalies.

This is great work. I too have a 7750G but with 6850M card. I was able to get it working with AMD5000 driver and personality Mangabey.

 

Only one question for 7750G, do you still use NullCPUPowerManagement? Mine could not boot without it. I am using Clover and would be really interested in to get native power management working.

 

Thanks!

Hello,

Installed OS X 10.10.1 used the custom dsdt and patched the lvds values for the pithecia framebuffer, everything works fine except the VGA, which does not work at all.

Had a look at the personalities and saw that pithecia does not support VGA anymore.

So my question: Is there any way to get VGA working in Yosemite?

Clover has a trick:

		<key>InjectEDID</key>
		<true/>

even if your EDID does not need changings.

What else do you need since the information is inside the archive you provided.

Connector at index 0
    Type [@offset 44606]: LVDS (7)
    Encoder [@offset 44610]: INTERNAL_UNIPHY (0x1e)
    i2cid [@offset 44680]: 0x96, OSX senseid: 0x7
Connector at index 1
    Type [@offset 44616]: HDMI-A (11)
    Encoder [@offset 44620]: INTERNAL_UNIPHY1 (0x20)
    i2cid [@offset 44703]: 0x90, OSX senseid: 0x1
Connector at index 2
    Type [@offset 44626]: VGA (1)
    Encoder [@offset 44630]: INTERNAL_KLDSCP_DAC1 (0x15)
    i2cid [@offset 44730]: 0x94, OSX senseid: 0x5

and you can copy a three port like pithecia to edit for your needs

 

0000000    00  04  00  00  04  03  00  00  00  01  00  00  12  04  01  05
0000010    00  08  00  00  04  02  00  00  00  01  00  00  11  02  04  03
0000020    10  00  00  00  10  00  00  00  00  01  00  00  00  00  00  02

 

but please first read this

Oh! Thanks very much!

Can u tell me how u did this? Cause I need it to know for future. And I need Transmitter and Encoder information, I can't edit fb without it.

Use redsock bios decode. It gives you the transmitter and encoder ( not sure if it gives the correct value or not, some have been reported wrong )

Hello all, after trying to get my 7670M to work for a week, without success, I decided to post here..

 

I didn't understand how to patch/inject the EDID into the DSDT, not even where to get or patch or download the ATY section in the DSDT, is missing from my DSDT..

 

I've uploaded the DSDT, IOReg and the Bios

 

It doesn't have an Intel GPU, the notebook only have the 7670M

 

Any ideas?

 

Do i need to create a new topic or it fine posting here?

 

Thanks!
