GUIDE How to Enable Thunderbolt 3 Hotplug on macOS

Hmm I swapped it and set the ACPI path accordingly but the same issue, after some testing, I disabled the TB3 SSDT and kept the DTGP SSDT enabled, which seems to be the cause of the Prohibited Sign

That means its conflicting. Can you enable verbose and provide the boot video?

Its an USB/AHCI controller issue. There are so much issues with the AMD USB Mapping.

However, it seems like there is a huge mistake in the config.plist. Instead of using SSDT-USB-Reset.aml, you have it SSDT-US-Reset.aml, which causes this particular SSDT not load leading to this error. Correct the SSDT name in the config.plist and then check.

Yeah I read about all of that which is why I included the Thunderbolt USB controller. Anyways, I went back and fixed the typo in the USB Reset SSDT, and no luck

If you did that, its wrong. The USB ports for TB are mapped via its own SSDT and must be excluded from USBPorts mapping.

Ahh okay, I went back and made the changes to UTB.Kext, and the SSDT, no difference though :/

Attached is another copy of my EFI, IOReg, and a screenshot of Hackintools PCIe device

(P.S. The SSDT-DTPG and TB3 are disabled in that config.plist so I can boot.)

Umm, maybe the system has some other EFI in any ESP?

It could be possible that NootRX and UTBMap are causing conflict in some way.

Hello,
Can anyone help me set up HotPlug on my system?
Mac Pro 2019 Tahoe 26.0.1
OpenCore 1.0.5
AsRock B760M Pro RS/D4
Intel i5-13700F
DDR4 32Gb
Vega RX64 8Gb

Thunderbolt devices only work if they're connected before boot.

I looked at this thread, but unfortunately, I still don't understand if it's possible to enable HotPlug. If it's possible on my board, please direct me to instructions on how to do this.
Do I need to flash something with a programmer, or can I just use kext and configure the bootloader?
I have an Xgecu T48 programmer. If you could tell me where I can find step-by-step instructions on how to flash it, I'd be grateful.

This thread is dedicated to TB3 only. TB4 lacks full driver support, and has limited support.
