Connect Ethernet on MSI Z170-A Pro?

[IronCraftMan]

Hello, I just recently successfully installed macOS Sierra (10.12.4) on my 6600K, GTX 1060, MSI Z170-A Pro motherboard and now I can't seem to get ethernet to work. Does anyone have any advice on how to get it connected, as well as what (if any) drivers I'd need. Going to the website for my mobo shows that it has Realtek PCI-E Ethernet. I have tried to install Realtek drivers from MultiBeast, but it fails and the log says "Mounting EFI failed. Exiting."

Any advice would be greatly appreciated.

Any advice would be greatly appreciated.

Try to install the kext manually :
Remove any previous failed attempts from /Library/Extensions and /System/Library/Extensions.

Open Finder and browse to /Library/Preferences/SystemConfiguration/ then delete these two files :

• NetworkInterfaces.plist
• preferences.plist

Download RealtekRTL8111-v2.2.1.zip and put the kext from the zip file on your desktop.
Download and run KextBeast selecting /Library/Extensions as the location.

In Terminal :

sudo kextcache -i /

Press return, type your password (it will not show on screen), press return again and when the command has completed, restart.
