Thunderbolt 3 failing but USB-C fine?

[Rammy37]

Hi all

Long time lurker but new poster!

I have the 2016 MacBook Pro with 2 Thunderbolt 3 ports. Suddenly and randomly, System Report now states "Thunderbolt: No hardware was found" and no Thunderbolt adapters seem to work. I also can't seem to use a USB-C to HDMI adapter, so I have no way of using any external screens.

Weirdly though, direct USB-C devices (flash drive, USB-C to USB-A adapters etc) function absolutely fine.

Is it possible for just the Thunderbolt chip to get hardware damage but the USB-C part still to be able to function correctly?

Thanks in advance!

Hey, I'm having the exact same problem with my MacBook 2017 . Have you managed to find a solution?

If you have a 12" MacBook, those only have USB-C and do not support Thunderbolt.

Sadly not. Still happening. Tried absolutely everything - upgrades, downgrades, PRAM reset, the lot. Still no joy ☹️

No, it’s the 13” pro. I took it to Apple and they said that it’s should show hardware for thunderbolt 3.

Same. I took it to Apple and the only thing they said they could do was replace the logic board.

Hey, just found out that one of these could help us. Still looking for a reasonably priced Mac compatable one but essentially, anything from usb to display port with an external graphics card should work . https://www.displaylink.com/products/usb-adapters

Hey, just to let you know that I found a way around the hardware issue. I bought this usb-c to display link device:

Kensington VU4000D USB 3.0 to Display Port 4K Video Adapter

With more and more people realizing the productivity gains of working on a 4K monitor, Kensington has an easy way for you to upgrade your laptop without the need for a 4K graphics card. The VU4000D 4K Video Adapter simply plugs into a USB 3.0 port on your laptop and goes into the DisplayPort on a...

www.amazon.co.uk

It only delivers 30hz 4k to one screen but there are better models with more outputs. A lot of them say windows only but from what I’ve read, they all still work on Mac, they are just not officially supported. As long as you have the latest displaylink software, it should detect input from the usb device.
