Awsome!!! 

 i still have some trouble with clover! black screen!

i disabled optimus with dsdt but nothing

also i add your string in config but doesnt work. (maybe wrong place. i added it in graphics)

 

I fixed an applehda kext for alc270! try it and tell me if it works. i have A55VD with alc270 but i dont know if its the same.

 

Thanks for your clover method!!!
