I am using a 13" MacBook Pro (mid 2012) and I have upgraded to OS X 10.11 El Capitan a while ago. Last night before going to bed I switched off the computer. Since this working the built-in Ethernet that was working fine does not seem to work anymore. I have deleted the network interfaces and rebooted the system, but still it does not show up in the network preferences. Is there a fix? What should I do?

For a very short window (a few hours) - Apple pushed an update that disabled the ethernet driver for some of the Macs.
If you can connect to WiFi and run this command:
sudo softwareupdate --background
That would fix the issue if yours failed to operate due to this bug. The details are covered at
Also some more details are on this post:
