GUIDE How to Enable Thunderbolt 3 Hotplug on macOS

[EliteMacx86]

Ok great! I'll try to flash it as soon as I land in Indonesia next week! I don't have my TB in hand right now, but if I did, would it still work without the hotplug capability?

Thanks again!

Flashing or without flashing, with the help of SSDT, you can have Hotplug functionality.

OK good! But right now, when I plug a USB-C device in it, I can't see it show up. I tried with multiple USB-C devices. My external SSD has the light flashing, but not connecting.

Sorry, missed the IOReg. Here they are!

Your SSDT is not adapted correctly for the system. The IOReg has the following path.
PCI0.GPP1.PT02.PT20.X162

Whereas, your SSDT has the following address which is incorrect.
PC00.PT02.X162

Thanks for the info! I'm a bit lost on where to put what in the SSDT though aha first time for me going that deep in this stuff. Don't want to ask too much, but is there a way you could send me a corrected file I could compare with my old one and learn from it?

No. You should consider reading the guide. The guide already explains how to change your ACPI path.

I did read it, but I don't understand how to insert my 5 part path in a 3 part path in the SSDT. How do I split it to do the replacement when doing the find+replace thing..?
