Changing default kext for Ethernet

Recommended Posts


I have a slight problem with my Ethernet. It works but occasionally drops out and I need to reboot.

Currently it is running on the realtek 81xx next but I have installed the realtek 8111 kext which I believe is the right one. Motherboard is GA-Z87-HD3

How can I get the correct kext to load at startup?

Also, is there a fix for the Ethernet needing a reboot, I remember having the same issue in Linux where if a cable was unplugged the system needed restarting to find the network. Is there a way to make os x automatically reconnect like windows does?

Im facing the same problem, same etherenet card i guess, my motherboard is, Gigabyte GA-970A-UD3 Rev.3, ehternet works, well unless my internet connection for some reason drops (this happens all the time with my shitty internet provider), so in windows this is no problem since i just turn off my modem to get internet again, but in osx if i do this even if in the modem the DSL light is on and working, osx just don´t work with the ethernet unless i reboot the system, anyone with any idea maybe?, i checked the kext and actually change it but i noticed that is the same version than before so not idea which kext should i use.

When you installed the Realtek81x kext in S/L/E how did you install it? Which version of OS X are you running? Mountain Lion, Mavericks or Yosemite?

Hi IonGeneral, well, i installed the kext in 2 ways and nothing, first i tried downloading the kext and install it with kext wizard and then repairing permissions and rebuild cache, with no result, always the same, also i tried to install with Linx2Mac, but still nothing changed, in every try i reboot the hackintosh, but no luck, im using Mavericks 10.9.5.


Thanks in advance!

@Josue Orozco try this way. - Use Kext Wizard to install the RealtekRTL8111.kext directly into System/Library/Extensions. Then Find IONetworkingFamily.kext. Open it's contents and place a copy of "PCGenRTL8139Ethernet.kext" directly into "SystemLibraryExtensionsIONetworkingFamily.kextContentsPlugIns".

    • Sierra installed without any issue, but cannot get GT620 to work. Installed Cuda and Webdriver and boots without issues, but home screen wallpaper disappears and screen becomes black. Is this card supported on Sierra?
    • I get this message no matter what I do, I've tried changing my SMBIOS to a newer model to no avail. Anyone no how to get the second install boot to work?
    • This is my first time doing Hackintosh. I've several other machines running Mac using UniBeast and Multi beast. I wanted to try Hackintosh Vanilla. So far, no luck. I followed the Guide and MacPwn Mojave Guide. 
    • Hello! I wanted to install MacOS High Sierra, but the SSD does not appear in Disk Manager. I have a Samsung Pro 840 250GB. Is there a Driver for Intel Gigabit 82579LM Network LAN for MacOS High Sierra?
    • This is my very first post and have looked around the forums to my question but I wasn't able to find the exact specifics that I need. This is my very first windows/mac dual boot project. I chose to attempt high sierra and I hope I am posting in the correct area. High Sierra seemed to be the newest that is possibly more stable than Mojave so I chose that. I'm reaching out to the more advanced builders and experienced people. I'm currently running Win 10 as of now and bought a separate SSD to install a macOS on. Before I invest time and energy into this. I'm wanting to get the best recommendations on what OS I should choose , if my hardware will be up for the task and my best plan of attack. I'll be honest I'm not ready to bang my head on the keyboard for hours. I've been there and done that.  My hardware was some of the best at its time in 2011 and I'm not 100% confident it will work with a more up to date macOS I'm also concerned about drivers for my GPU.  All input is welcomed   Here are my current specs:   CPU
          Intel Core i7 2600 @ 3.40GHz    28 °C
          Sandy Bridge 32nm Technology
