Why can't I install it successfully? I have disabled SIP, thank you！

I already installed it， but it doesn´t work. I can see I have a FireWire equipment in my MAC, but it cannot recognise to be as sound equipment. What should I do. Thanks

Does anyone know how to copy AppleFWAudio.kext to Exrtensions?
