Read Instructions Carefully
These are the kexts and DSDT for the asus k53sv, Everything works except: nVidia GT50M due to the nVidia Optimus switching technology and the Intel wireless card.
If you want the wireless to work you can buy an atheros AR5B95 on ebay/amazone. The kext's work in Mountain Lion/Mavericks/Yosemite.
I added a patched bios wich unlocks native powermanagment and all advanced bios options. The bios is only for an Asus K53SV/X53SV/A53SV!!!! If you want it for an other Asus K53** mail me. It is a risky procedure, if it fails i am NOT responsible in any way. It is on your OWN RISK.
Native powermanagment wil fix kernel panicks about power, enables you to install all newer versions of OSX. And in some cases windows will work faster.
