Dell TB15 partially working #33

Closed peacechen closed 5 years ago

Thanks @rgov for sharing this project.

I am the unfortunate owner of the TB15 dock. Works well on a Dell laptop after some updates to both Windows and the TB15 firmware. However it wouldn't work initially on a MacBook Pro with OSX 10.14. It would charge, but no devices worked.

After using Thunderbolt3Unblocker, the Power Delivery, USB and Ethernet ports work, but DisplayPort/HDMI outputs do not.

Here's the spew from System Report. The indentations didn't carry over, but it looks to be nested from Bus -> Cable -> Dock.

It looks like T3U is working fine—it allows the rest of the system to "see" that the TB15 is plugged in. However, once that is done, T3U's job is over. It does not know anything about video output; that's the responsibility of some other driver. Unfortunately, it seems like you don't have a driver that can deal with the video ports on the TB15.

Please see also the thread about the TB16. I don't have either of these devices and don't know anything about them, unfortunately. https://github.com/rgov/Thunderbolt3Unblocker/issues/28
