thanks to all of you brothers and a big thanks to Mohammed for his great efforts that made this pice of hardware get smoother with OSX
but there are some little problems most of us are struggling with
Right now I'm on 10.7.1 and I have the following issues
1- some little freezes especially when open apps in fullscreen.
2- artifacts are showing sometimes.
3- Webcam is not working I have the same problem that Radiking is having (the lED indicator near the webcam is on but webcam is not working).
I noticed that some of you
guys are on 10.7.3 and everything seems fine. this is strange because when I updated to 10.7.3 the system become unusable due to the constant freezes and artifacts
delete all ATI,InteL GMA 950, X3100, HD ( Be careful dont delete 4 HD3000 kexts, AppleIntelIntegratedFramebuffer.kext, AppleIntelSNBGraphicsFB.kext and AppleIntelSNBVA.bundle, we only need these 7 Kexts ) and finally delete all NVIDIA Geforce Kexts and once again clear the caches using kext utility ( from mahesh kondrajus thread ) and restart comp u will no longer have freezes and artifacts my system is very much stable now .if ur dual booting u can delete from windows with the help of mac drive to see mac hdd then go to system/library/extensions and delete them then restart with these flags -v -f coz u might get kp use kext utility again to clear cache again and restart everything will work super smooth..i m using google chrome very stable that other browsers
