It will work only in 32 bit (arch=i386).

You need EFI string or DSDT patch http://Olarila.com/forum/viewtopic.php?f=7&t=56

You can use DSDT Editor to apply http://Olarila.com/forum/viewtopic.php?f=19&t=634

thank you for the reply,

I'm running in 32bit

i have applied the EFI string and DSDT patches.

i think i need correct drivers for GMA950 0x2772

i tried many kext versions and combinations of versions but only these two give me better graphics

AppleIntelGMA950.kext v6.0.0

AppleIntelIntegratedFrameBuffer.kext v4.2.0

i have attached some info of my computer

thanks
