Hi,
I installed your FN keys kext v.2.5.5 and all keys worked except brightness keys f5/f6. So I try to compile the ALS patch using dsdt editor but it has compile error "object not found or not accessible from scope (PCI0.LPCB.EC0.RALS)
Could you let me know where did I go wrong.
Thanks,
Machine is Asus X501A.
