2013 iMac Thunderbolt partial failure - External Displays Work, but not thunderbolt devices
I have read other threads relating to the failure of Thunderbolt ports on 2012/2013 iMacs, particularly my i7 3.5Ghz model.
In my case I have something a little different.
Like the others, my system says " Thunderbolt: No hardware was found."
If I plugin a thunderbolt audio device or external drive its not recognised - Yes, they work fine on other Macs.
However, my external displays using a thunderbolt to DVI adapter work fine through the non existent thunderbolt port.
My question is "is this still a hardware failure issue?"
PS No amount of SMC or PRAM resets have helped.
