Thank for starting this topic, I have the same problem with my asus N56VZ.
I managed to make OSX to detect the Intel 4000 but I think it's not fully activated.
There are still some glitch here and there...
@Rampage Dev :
I've take a look at ThibaultAnd's dsdt and IOReg, although I'm not really understand
my DSDT is missing the Geforce part (something on Device "(PEGP)" ), I try copy and paste with no luck
can you also modify my DSDT (I,ve attached the dsdt+ioreg file and also a screenshot)
I assume you are an Indonesian?
how is the progress on your laptop, is it running smoothly?
