X4000 is missing, so I guess you won't have acceleration...

I can't boot without modify the X4000 info.plist , i had the same issue after upgrade 10,12,1 to 10,12,2 and also 10,12,2 to 10,12,3

Perhaps the problem is here :

Modifying the Info.plist will mess up the file's permissions, so if you didn't fix them the kext remains in an unloadable state. This will "solve" the boot to black screen issue, but you won't have acceleration. You could also delete X4000.kext, it should have the same effect.

How may I fix them ?

You're right, I mixed up the order.
