As I can see whe have two different ways to get our goal tranduyquangs one uses original apples patched kexts and pere uses vodoos ones for batery and sound. I would prefer to get as much hard as posible recognised by system information. But as far as i know if you use original apple kexts they can be erased with system updates.
Perhaps to determine wich approach gets better performance from our hardware both of you can make some brenchmarks to work together to achieve the best hackintosh.
I will delete powermanagement kext and see what happens
There is some ways to obtain hackinosh working, you can choose which kext/way that you like. For more exp and for getting a better performance hackintosh I recommend that you should try all and figure out the best way. Cheer
