Hey, sorry about the outdated kexts but i think by now everyone should have learned how to patch your AMD6000Controller.kext, it is a simple task and there are instructions here how to do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

    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

@Trucker

 

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:

10.9.3 requires nothing special to be done, if your DSDT worked before with patched kext, it should work on 10.9.3 as well.

You need to read my post above very carefully. You used the framebuffer which requires custom EDID injection, there are two framebuffers.

Hello :)

I'm having some problems with my gpu : AMD Radeon 6470M on OSX 10.9.1 (iAtkos M) with the clover bootloader.

Here's my VBIOS extracted from AIDA64: Attached File  vgabios.dmp.zip   38.98KB   2 downloads, and the .kext: Attached File  AMD6000Controller.kext.zip   973.96KB   0 downloads.

I read through 17-19 and 31-32 as indicated in the first post but did not find any clue to fix this.

 

Edit: Added the AMD6000Controller.kext

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.insanelym...d-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!
