Ethernet Card Not Being Detected On My iMac 20-inch Early 2008

Hello


A few days ago my ethernet started playing up on my mac. I tried different cables and routers but no fix. All my other devices are fine through the same port. I tried deleting and then adding a configuration on the network tab of system preferences but now the ethernet option is gone.

I then went into system information and found a nasty message:

I really need help. Wi-Fi just isn't good enough for me.

iMac (20-inch Early 2008), OS X El Capitan (10.11.3)

Apple has corrected the problem:

If the Ethernet connection on your Mac stopped working recently - Apple Support


So, you have to "force" the silent update:

  1. Open the Terminal app.
  2. Type this command to update to the current version of the “Incompatible Kernel Extension Configuration Data” kernel extension:
    sudo softwareupdate --background

  3. Quit Terminal and restart your Mac.
