You must come to know the particulars of faramebuffer.

First. You must get Vbios from AIDA64 or to make full DarwinDumper.

After that you can make an injection withou help of bootloader, namely by DSDT.


If you want I try to help you with faramebuffer.

Open AMD4600Contrpller /System/Library/Extensions/AMD4600Controller.kext/MacOS/AMD4600Controller

Find Shrike using hexedit

02  00  00  00  00  01  00  00  09  01  00  00  20  01  02  02
00  04  00  00  04  03  00  00  00  01  00  00  10  00  01  01

And replace by that

02000000 40000000 0901 0000 12 04 00 07 (LVDS)
10000000 10000000 0001 0000 00 10 01 01 (VGA)
00000000 00000000 0000 0000 00 00 00 00 (-)

Also you must add your dev-id(See blue)



<string>0x94901002 0x94881002 0x95531002</string>
After all use GraphicEnabler=Yes and AtiConfig=Shrike
I advice using Chameleon wizard so as not to  make surplus mistakes.

I cant find the code to replace, I'm using HexEdit.


My dev-id isn't 0x95531002?

Right it must look so. 0x95531002. It was my mistake.

What system do you use? I use mavericks DP5 and I checked it exists.

Try this faramebuffer, and give me DSDT if it doesn't help.

Use first FB

Install AtyInit

Change macmodel to MacBookPro5,1

Try GE=Yes/No but without ATIConfig

If it won't help again, I can suggest you using this -DSDTMethod from this topic. 


and try Clover. I think it is the last hope to inject your card


DSDT can be gained from AIDA64 or DarwinDumper etc.

Here is correct sample Garphics part for Clover


Change a little for your card.

Rename your Vbios to 1002_9553.rom

Try launch your Graphics with the help of Clover. You can use it on USB stick as well.

Don't forget where you must put Vbios.(See above)

Add your UUID to config.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
        <string>Apple Inc.</string>
        <string>Apple Inc.</string>
        <string>Apple Inc.</string>
        <string>MacBook Pro</string>
        <string>Part Component</string>
        <string>Apple Inc.</string>




02000000 40000000 0900 0000 12 04 00 07 (LVDS)
00000000 00000000 0000 0000 00 00 00 00 (VGA)
00000000 00000000 0000 0000 00 00 00 00 (-)

If again without success try these values 01 02 03 try them all

Also you can try zeroize transmitter 12->00

I gave you ready config, and suggest replace UUID by yours. But it's not obligatory as it doesn't have an influence on Graphics.

About Vbios see here.


And I renamed correctly Vbios for you. See several messages atop.

I have to change the code in EFI/CLOVER/config.plist with that?
