• If the Ethernet connection on your Mac stopped working recently, follow these steps to restore it (includes how to check System Information to find out which version of "Incompatible Kernel Extension Configuration Data" is installed. If you have version 3.28.1, you need an update. Doc includes how-to. No OS version is mentioned but I believe this is related to El Capitan 10.11.3 installed via software update.)
  FYI: If Apple's instructions do not work to update to version 3.28.2, see the download link from "joegc123" in this apple forum thread.
