I have a piece of Gigabyte Rev1.1 Z77P-D3
My motherboard is Rev1.1, installed Z77PD3_Rev_1_1_HighSierra, the system is 10.13.2, but the sound card and network card can not work.
I come from China, English is poor. I am using Google Translate now, I hope you will understand.Now you can normally enter the system, but the sound card and network card can not identify, I need to do?
Audio is Realtek ALC887
Network is RTL 8168/8111 Or Atheros AR8151
Looking forward to your help
PS:AtherosL1cEthernet-1.2.3.zip and Oz-AppleHDA-ALC887.zip to EFi/Oz/Darwin/Extensions/Common not work.
Also need DSDT.aml?
