Ethernet disappeared randomly after Mavericks installation.
Mavericks seems to have killed my Ethernet port on a 2012 (mid) MBP 13".
I have re-installed, reset PRAM and SMC to no avail. It was there 2 days ago. There has been no trauma to the unit at all.
Is there a way to test this port / fix it without replacing the logic board? thanks.
Is this a good question?
