Enabling NVIDIA graphics on unsupported SMBIOS

[alexthebest28]

You need to use an SMBIOS that has nvidia. Either that or you have to patch AppleGraphicsPolicy.kext (or some such).

As already said i did patch the AppleGraphicsDevicePolicy kext with the Board-ID of the MacBookPro 8,1 but it didn't work... Of course i can just use the iMac14,1 SMBIOS but it's very unstable...

Maybe you didn't do it correctly...

Ok i got it working with an iMac12,1 SMBIOS and patching the AppleGraphicsDevicePolicy.kext. I have no clue why it didn't work with the MacBookPro8,1 SMBIOS..


Anyhow, I've got a question a little bit off-topic: Is there any way to enable Brightness with a Nvidia Graphics Card and without Intel HD Graphics?

I'm sure there is. You should start by patching with "Brightness Fix", then test.

I already did, only the Brightness Slider appeared inside the settings panel but nothing more...

Then you have more work/research to do...

alexthebest28 - can you walk through, in somewhat simple terms, how you got your card working from start to finish?

I am trying the same on my Thinkpad. Thank you!

The fix is well known.

Your choice:
- use an SMBIOS appropriate or Nvidia
OR
- patch AppleGraphicsDevicePolicy Info.plist to include your chosen board-id

thks again, RehabMan.

i saw your post everywhere.

here is what i have done
it(i mean nVidia card) works on mbp9,1 but i need to change to mbp8,1 cus my CPU is Sandy Bridge
1. use Pike's patch like this:

<dict>
                <key>Comment</key>
                <string>AppleGraphicsDevicePolicy (board-id) Patch © Pike R. Alpha</string>
                <key>Find</key>
                <data>
                Ym9hcmQtaWQ=
                </data>
                <key>Name</key>
                <string>AppleGraphicsDevicePolicy</string>
                <key>Replace</key>
                <data>
                Ym9hcmQtaXg=
                </data>
            </dict>

the edid has injected already:

<key>Graphics</key>
    <dict>
        <key>CustomEDID</key>
        <data>
        AP///////wAwrqFAAAAAAAEUAQOAHxF46szOmVhQjiYkS1MAAAABAQEBAQEB
        AQEBAQEBAQEB+idADmGEDDBAKjMANa4QAAAYzyNAmmGEDDBAKjMANa4QAAAY
        AAAADwCpCTKpCTIZCQAGr1YxAAAA/gBCMTQwUlcwMiBWMSAKAAg=
        </data>
        <key>Inject</key>
        <dict>
            <key>ATI</key>
            <false/>
            <key>Intel</key>
            <false/>
            <key>NVidia</key>
            <true/>
        </dict>
        <key>NVCAP</key>
        <string>0400000000007900020000000000000700000000</string>
        <key>NvidiaSingle</key>
        <false/>
    </dict>

after that, nothing changed.

2. change AppleGraphicsDevicePolicy like this:

/System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist

                <key>Mac-94245B3640C91C81</key>
                <string>none</string>

MacBookPro8,1 Mac-94245B3640C91C81

after that, nothing changed.
