The driver I am using is ~ % system_profiler SPEthernetDataTypeĪnd ~ % kmutil showloaded |grep -i .cdc any thoughts on what logs to check when it does happen? I have searched the system logs but have yet to find any smoking guns. But the disconnects that required a restart were the bigger issue. In terms of my previous issues, I remember that when I clicked the little lock in the browser to view the cert, it would crash my computer. But it still uses the same Realtek 8153 chip although am using the native driver though now, AppleUSBECM.kext I got a new USB ethernet adapter because the old one had lots of issues (hence the gist in the first place). I got a new USB ethernet adapter and use the native driver Perhaps clear the Kernel cache sudo rm -rf /System/Library/Caches/

Special thanks to alreadystarted for the heads up in the Skylake Starter Guide.

I do not take any credit for these works. Official versions of both drivers should be available soon. I have compiled the fixed working sources in Xcode from theracermaster and jsmcconn's version of Mieze's driver and from hnak's driver for ease of testing. With recent changes to sources, both Mieze's IntelMausiEthernet and Hnak's AppleIntelE1000e.kext now enable all i219 variants. For months now Intel i219 ethernet on Skylake 100 Series motherboards has been unsupported. Building a CustoMac Hackintosh: Buyer's Guide
