7480: TB3 problems


Recommended Posts

Hi team!

I have almost dream machine. 

I just can't win with Thunderbolt3 


Setup: 7480 i7 7th gen


3xUSB + 1x TB3

macos 12.4

TB3 device I try to use: Blackmagic ultrastudio 


I think my ports configuration is messed - but I tried to remap usbmap and this doesn't help.


If I connect USB 3.2 Stick to Thunderbolt port - this is detected correctly

If I connect Thunderbolt 3 device - this is not detected at all.

If I connect USB 3.2 usb stick to top left usb port - this is not detected - but usb 2.0 device is detected correctly. I can live with it though ;)

I attached both IOREG files with connected usb stick and connected thunderbolt device. 

I exluded cable problem as I have a dualboot and same setup works perfectly fine with Win10 boot.


I don't need hotplug - as long I have working TB3 I will be more than happy. Please see my  configs. 


Any help will be appreciated.

The EFI posted has too many things not going well. Trackpad does not need rebuilds, the EFI is out of date, I posted an updated EFI if you start, pass new ioreg and test the TB3. If you have problems, settle down. OC 0.8.3 + kext 15 \ 7 \ 2022.
