Unable to set up lan in macbook pro ( with retina display) In macbook pro there is no lan port, for that I bought lan to usb connector.

But I am unable to setup net-connection.

In System preference > networks there is no ethernet option.



I tried this link https://discussions.apple.com/thread/4835488?start=0&amp;tstart=0
There's a add button at the bottom right portion of that screenshot. Click it.

It will present you with options to add a new interface, and if wired Ethernet is available on your Mac, it will appear there.
