Its absolutely normal and will not appear unless you activate the Thunderbolt Bus. To enable Thunderbolt Bus, you'll need to flash the custom firmware. It's already covered in the FAQ section.

It appears that your implementation for Thunderbolt is not correct. You have only completed the first phase which is to enable Thunderbolt. In order to make it functional including HotPlug, you need to implement it.

Thanks for your reply.
I have read the post and I have some questions.

Q1: Should I flash Maple Ridge 4C 2020 with custom firmware ?
It seems Maple Ridge is native supported by macOS, but I not sure.



Q2: If I don't need to flash custom firmware, should I proceed to section "Enabling Thunderbolt 4 Hotplug" ?
It seems there is no SSDT samples for Maple Ridge Thunderbolt 4 in HackinDROM website. There are only SSDT samples for Maple Ridge Thunderbolt 3 (Asus ROG Z590 Maximus XIII Hero).

So the Q3 is: Which Thunderbolt Controllors should I select on HackinDROM website?

Thanks again.

Q1: Should I flash Maple Ridge 4C 2020 with custom firmware ?

No stable fully working Custom Firmware yet.

It seems Maple Ridge is native supported by macOS, but I not sure.

In fact, macOS has no support for Maple Ridge as of now. This is because Apple uses a different TB4 chip instead of Maple Ridge.

Q2: If I don't need to flash custom firmware, should I proceed to section "Enabling Thunderbolt 4 Hotplug" ?

Yes, indeed.

It seems there is no SSDT samples for Maple Ridge Thunderbolt 4 in HackinDROM website. There are only SSDT samples for Maple Ridge Thunderbolt 3 (Asus ROG Z590 Maximus XIII Hero).

You should be good to go with that. Maple Ridge is Thunderbolt 4, not Thunderbolt 3.

So the Q3 is: Which Thunderbolt Controllors should I select on HackinDROM website?

Go with Asus ROG Z590 Maximus XIII Hero.

Really appreciate for your help. I will try with Asus ROG Z590 Maximus XIII Hero.

Surely!

Hi, I have edited the aml file according to the post and also added ThunderboltReset.kext and TbtForcePower. efi file to OpenCore.
But the Thunderbolt Controller have not been successfully driven.
Have I did something wrong or missed something ?
If you need any missed information, please let me know. Thank you very much!

As mentioned in the previous post, this is absolutely normal and does not impact the functionality.

From the pictures, the implementation looks fine. But if the HotPlug isn't working, you'll need to provide BIOS Settings, the Thunderbolt Device you're testing.

HotPlug is not working, and connect my Thunderbolt device before boot the system is also not working. My USB drive connected to the Thunderbolt device cannot be detected.

My Thunderbolt device is wd19tbs.
