Why Can't I Select Ethernet On My MacBook Air From Setup Assistant?
Why won't my MacBook Air let me transfer information from my old Mac using Ethernet in the Setup Assistant?

This issue usually occurs if you connect the two devices after start up. Close Setup Assistant and shut down your Mac. Connect the USB Ethernet adapter to the MacBook Air and then start up the Mac again.
