i installed 10.7.3 on my laptop, it works fine, except for graphics ( intel HD or nVidia GT520M - none works). I've tried several solutions, but every time i must delete AppleIntelSNBGraphicsFB.kext to boot, else it freezes al apple boot screen.
- Intel Pentium B950 @ 2.1ghz
- 4gb DDR3
- Intel 2000HD integrated graphic card
- nVidia GT520M (it doesn't work at all, probably because Optimus, but not sure)
If someone can help me I'll be very grateful, since I'm trying for 3 days to fix this.
