Ethernet Problem.
My 2 y/o iMac,lost his Ethernet connection in the System Preference/Network.
it doesn't appear in the list,and i can't add it back with the + option.
i'm really lost with that guys.someone has a answer for that?
do i need to install from scratch the operating system,just to make it appear again?
and after that i need that the iMac will see his IP address.
he didn't saw it before the Ethernet connection lost.
in the end i need that a PC computer will read the Mac.
without the Ethernet and the Mac IP address,it won't function.
Thanks,
