GUIDE How to Enable Thunderbolt 3 Hotplug on macOS

[EliteMacx86]

It's an external SSD connected with a USB-C cable. Nothing fancy. I'll test some more tomorrow!
Thanks mate

Did you tried to connect it before booting to Mac? Probably, due to missing BIOS settings.

Hey everyone!

Hoping someone could help me out or point me in the right direction. I built my Hackintosh about 4 years and have been using it as my primary music production machine. Here is the run down:

ASUS Strix Z370
Intel i7-8700k
Asus ThunderboltEX 3
Focusrite Scarlett Thunderbolt Audio Interface

I spent a lot of time reading/configuring the machine to work with my thunderbolt card and it's working great. The Scarlett is available in both Windows and Mac OS, low latency, reliable.

However, the one thing I never got working (it wasn't well documented at the time) was the damn HOTPLUG! Now I see people have got it working and I'd love to give it a shot.

Problem is, I have almost totally forgot what some of the KEXTs were for and how to properly configure my SSDT/ACPI (I also feel as though there may be unneeded KEXTs and configs in my EFI - it was a bit of trial and error during my initial build and I left it alone when everything seemed to be working). When following the guide here, I seem to have everything in order but I must be missing something because it's not working. Excuse my ignorance

Any help would be greatly appreciated. Thank you!

Incomplete PR files attached.

IOReg and Kextcache output is missing.

Post has been updated with the IOreg. What is the command I need to run to get you the Kextcache output?

sudo kextcache -i/

Remove SSDT-TB3-OTHER.aml

The configuration is not proper but the Thunderbolt implementation looks good.

I have removed SSDT-TB3-OTHER. It has not affected the use of Thunderbolt but hotplug is still not working.

Can you elaborate on what is wrong with the config?

Have you tried to check the Hotplug using any other Thunderbolt Device?

The configuration is not as per the guide.

Provide everything as mentioned in the Problem Reporting section of this guide.

No, unfortunately I don't own any other Thunderbolt devices. What i'm looking to accomplish is be able to power on/off my audio interface (it gets quite hot if left on for long periods of time) without having to restart the machine.

Any other suggestions to test or try?

Thanks again

Here's what you can try and report the issue.

Keep your interface connected before booting into Mac. Once the interface is connected, try to disconnect and then connect and check whether it works or not. Is your AIC flashed with custom firmware?

Okay -

Audio interface connected and powered -> boot mac -> audio interface working and available in system -> keep interface powered on and disconnect from mac -> reconnect -> audio interface no longer available.

No, no custom firmware on AIC

I should also mention I am using an Apple branded TB2 to TB3 connector between the interface and ThunderboltEX card.
