GUIDE How to Enable Thunderbolt 3 Hotplug on macOS

[EliteMacx86]

Hi There, and thanx a lot for your fantastic guide
I have a gigabyte z390 Gmaing SLi and a try to put the flashed GC titan Ridge card (with the cable pin 3 and 5 linked) in different pcie slot on my board.
Latest BIOS Version F10j.
Only the PICex2 slot (the bottom black slot) can show RP19 in IOREGISTRY. The other reccomended slots like the PCIex16 show me PEG0 or PEG1. I tried to change the address PEG0, PEG1 or PEGP with MaciASL but nothing.
Only way to see the card work is to put the card in the PCIex2 slot with RP19 address. and it works. But i cannot use the hotplug feature.

If I put the TBTforcepower.efi in drivers i receive the error:

Unsupported PCH SKU, LpcDevice 0xA305 !
GPIO ERROR: Icorrect GpioPad used on this Chipset (group=19 pad=257) !
Failed to write GPIO - Invalid Parameter
Error: Invalid Parameter returned from TbtForcePower.efi


Please can you help me?

Thanx a lot again

The above error is very normal.
This guide doesn't explains to flash the Thunderbolt Card or the onboard chip. You must flash the stock firmware and then continue with the guide.

Or Better, firstly can you suggest me in wich slot i have to put the TB Card? talking about the z390 gaming sli

You can install the Card in any available slot.

Thanx for the reply.
I Had just flashed correctly the titan card.

NEWS:
I solved 90%.
Now I can see on system/info/thunderbolt Apple Inc. Thunderbolt ad 40Gbps...OYYEAHHHHH

But I disabled the TBTforcepower cause i had the errore i posted here in the last post.
But seems to work. I use the UA Apollo8. Now i tried to turn off and again again, the system load correctly everytime the device.

To Sum all things.

Gigabyte Z390 GAMING SLI
GC TITAN RIDGE put in the Bottom Black PCIeX2 SLot
I plug also the Power connector into the TB CARD.
UNIVERSAL AUDIO Apollo 8 with TB3 add Card


I Updated the ACPI file following your Guide.

AND after a week that i work I can open a good bottle of wine and say.. YYEAHHHHHHHHHH


PS..... after some minute sometimes the TB cant enable the Apollo. I think the problem is the hot plug.
I'm using now the opencore loader, but i have the same issue with clover too

Here is....

When I put tbtforcepower.efi in /EFI/OC/DRIVER and I compile the config.plist
i receive this message.

If I do the same thing with clover bootloader I have the same error

No PR files attached.
The error is very normal and the guide will be updated soon for OC users.

Windows is a completely different OS. It's explained in the guide.
