Hello! Help me please. I have a late 2009 i7 27” iMac. When I plug in the Ethernet cable, which works properly on my pc, It says that ‘The ethernet cable is not plugged in’ Is that fixable?
I would first try a second cable. If that fails, I think you’ll need to inspect the connector on your system to see if small contact wires are mis-aligned or damaged
