Hello everyone,

i'm currently working on my Hackintosh and desperately trying to enable NVIDIA (NVIDIA GeForce GT 540M) support when using a MacBookPro 8,1 SMBIOS. After changing the SMBIOS section in Clover from iMac to MacBookPro (which fits my Intel Core i5 2410m almost perfectly) the screen stays black after the apple logo. I already tried adding the Board-ID (Mac-94245B3640C91C81) to the Info.plist inside AppleGraphicsDevicePolicy.kext which solved the issue for some but the screen stays black. I even tried to connect it to an external Display using a HDMI cable but not even this worked. I believe it's a problem with NVIDIA's Web Drivers but i'm not quite sure.
If it might help i will upload my DSDT:View attachment DSDT.dsl.zip

Thanks very much

What is the output of 'lspci -nn' in Linux Terminal?

You may have to inject EDID. As far as modifying the kext, make sure you rebuild cache after making the change.
 
I already tried to get the EDID on Ubuntu with "read-edid" or "parse-edid" but everytime it returned an error... I always rebuild the cache after installing a kext....

Use MonInfo in Windows to extract EDID. You'll have to search for information on the DSDT patch you need to inject the EDID data.

Great, so i have to reinstall Windows first?

Edit This is what get-edid returned
Code: 
ubuntu@ubuntu:~/Desktop/read-edid-3.0.1$ sudo get-edid
This is read-edid version 3.0.1. Prepare for some fun.
Attempting to use i2c interface
Looks like no busses have an EDID. Sorry!
Attempting to use the classical VBE interface

The EDID data should not be trusted as the VBE call failed

I'm sorry nothing was successful. Maybe try some other arguments
 
Ok, so I got the EDID from Windows and injected it with Clover's Custom-EDID. OSX accepted it and the new EDID appeared in the IORegistryExplorer. I changed the SMBIOS back to MacBookPro8,1 but the Display remained black. Any ideas?

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