Question: Q: Mac OS X 10.13.6 Killed my Ethernet Connection I just successfully downloaded and installed the 10.13.6 update and immediately following the reboot of my iMac Pro, my Ethernet connection is no longer functioning.
I just successfully downloaded and installed the 10.13.6 update and immediately following the reboot of my iMac Pro, my Ethernet connection is no longer functioning. If I manually pull the ethernet cable out of the back of the computer and connect using either WiFi 5G or 2.4G, I get connected to the Internet. Has anyone else had this problem? I've restarted my Asus router and DrayTek Vigor 130 modem twice, but to no avail. My wife's MacBook Air, which is still running 10.13.5, is connected to Ethernet via the Display Ethernet (to the same Asus router) and is running fine.
I can get by using the 5G WiFi but would obviously like to be able to use my ethernet connection as my main one. Erik Lars Hansen. I used much more sophisticated and complicated methods to find it-which didn't work at all!!! KISS is a good acronym most of the time-I wish I'd thought of it. I've been on to Apple Support since my machine is still under warranty/Apple Support. The tech and I determined that the ethernet port/hardware on the iMac is working but it is still not connecting, even after going through Reinstall from Internet in Recovery mode. I'm downloading the combo as I write this, and will try that before calling back to Apple Support.
Maybe I'll get lucky. I also note that I'm not the only person having troubled with internet connectivity.

I'll call Apple Support again tomorrow to see if they can help me get this fixed.
Strangely, during the first Support phone section, Ethernet connection worked while we were in a Recovery mode and launched Safari. I guess that proves that the Ethernet port hardware itself is working. Yes, and it suggests that probably some of the software running is causing a conflict. A few things to try: - recheck all the settings in System Preferences-Network - login to a new user account, and check if Ethernet is working correctly there - start in Safe Mode, login to your normal account, see if it is working - run Etrecheck from your normal user account and post its report here.
