Ok i thought it is EDID fault. but Mac is picking up the right EDID (checked with windows). One thing i noticed is when i type ioreg -l in terminal and search for the line "IODisplayPrefsKey" i find "AppleDisplay-4ca3" instead of AppleBacklightDisplay-xxxx. Is this something to worry about? P.S: I dont have BIOS option to disable NVIDIA or set DVMT or internal VRAM size.

Hey artur, thanks for replying. After injecting device properties (ID:04) in boot.plist, I'm able to boot and i can see that intel hd 4000 is running (in system info it shows 512mb intel hd 4000). My problem is the display is distorted with white and grey lines. I have so far tried editing EDID, editing appleintelframebuffercapri, and appleintelsnbgraphicsfb kexts. I Know that nvidia doesnt work . I get same display problem as given in the image link in the 1st post http://imgim.com/7544incif4741799.jpg. Please help me and thanks.

I'm having the exact same problem although my laptop is np550p5c-sn05in...i'm trying since 1 month...please help anyone.
