GUIDE How to Enable Thunderbolt 3 Hotplug on macOS

[EliteMacx86]

Thanks for this guide.
I can get it work on my HP EliteBook 850 G5. I have thunderbolt in legacy mode in BIOS and I can connect USB-C drive.
However it breaks sleep mode. When I tried to wake from sleep I needed to shut down and start again with this error:

panic(cpu 2 caller 0xffffff7f9e352399): "NHI0(MacBookPro15,4): thunderbolt power on failed 0xffffffff\n"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/IOPCIFamily/IOPCIFamily-370.100.21/IOPCIBridge.cpp:1398

Nevermind, I just get it to work!
Thank you so much for this solution. I can finaly switch TB3 in BIOS to "Native + Low Power mode".
All works including sleep.

Perfect!

 

[kecinzer]

Perfect!

BTW. I just tested that SSDT files are enough. I don't need kext and driver to work.

And does the Hotplug works without the kext and driver?

Depends on your IOReg.

This is very normal and already explained in guide.

TQ for replay

I've connected to My book thunderbolt 2TB but nothing came out

I tried with the thunderbolt Ultra studio Recoder, it worked. Just My book thunderbolt 2TB but nothing came out

is there another way to get it working?
