What's the best way to get my ethernet working? I've used the Chameleon Bootloader.

ga-z87m-D§H should feature a Realtek Lan- rtl81xx-chip. Try Realtek own driver http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false (offically supporting up to 10.7 but it works also on Mavericks). There will be no need to change any value at bootloader...

I think you have to extract the .kext from the .pkg and install it manually to /System/Library/Extensions/.

For extracting the .pkg open Terminal and enter:

pkgutil --expand path-to-pkg dir-to-extract-to

After browsing some folders you will find a .gz or similar file. Extract it by double clicking it.

I had the same issue. First make sure that you need Realtek's RT81XX Driver. I had RT8136. Here is what I did:


Download the Driver from here:


Its a Pkg File. Install it. Reboot.

It will NOT work initially.

Next go to Settings > Network > Select your Ethernet 

Go to the Advanced Tab at the Bottom. Go to Hardware. 

Use these settings:


Configure: Manually

Speed: 10 BaseT/UTP

Duplex: Full Duplex, Flow-Control


Click OK, and wait for about 1 minute. It will automatically connect to Internet and the Button will turn Green.

But it took about 1 Minute for me for the first time.
