X570 Creator Not Seeing TB Devices

I have the same ASRock X570 Creator and also purchased it for the on-board Titan Ridge Thunderbolt controller. Under Windows, everything works. But under macOS I see the following issues (same as you):

1. IORegistryExplorer shows that macOS detects all Thunderbolt controllers (Thunderbolt Bridge, Thunderbolt NHI, Thunderbolt USB 3 Controller). The device tree looks correct except that hot-plug attributes are not present. These are injected by an SSDT, but for now let's put hot-plug aside.

2. When booting macOS with Thunderbolt devices already connected and powered on (i.e. no need for hot-plug), they do not appear in IORegistryExplorer. In other words, just like your experience, no Thunderbolt device gets attached.

3. However, I have not yet connected a DisplayPort cable to the DP-In port. Not sure if that makes any difference, but it's worth a try. Will do so in a day or two.

4. When I boot into Windows (build 1903), all Thunderbolt devices appear and work fine. But then doing a soft boot into macOS still fails to connect any devices.

5. I am running BIOS 1.70.

6. In UEFI Setup (BIOS Setup) there are 2 settings for Thunderbolt:
   
    Advanced --> AMD PBS --> Thunderbolt ---- I set this to "Enable" (default)
    Advanced --> AMD PBS --> Security ---- I set this to "No Security"

With the Asrock Thunderbolt 3 AIC, other users have reported that UEFI Setup contains a lot more configuration settings. But on the Creator we just get the above 2 settings.

According to a technical support email to ASRock, both "Thunderbolt USB Support" and "GPIO Force Power" are enabled by default even though these settings are not exposed to the user.

If this problem cannot be resolved then alas I will have to sell this board and get the ASRock X570 Taichi and the Asrock Thunderbolt 3 AIC.

I just bought the X570 Creator hoping to connect to our Ultrastudio 4K via an Apple Thunderbolt 3 to 2 converter but the PC doesn't recognise it at all.

Did you ever have any success with this?

How? Doesn't work with me :( Please help

Hi!

I did open a ticket for support. After weeks of contradictory answers, Including thelling me the motherboard TB port was faulty and I had to RMA it (which I didn?™t) they finally sent me an unrealeased Thunderbolt driver issues directly from their headquarters (as they said), and finally I have Thunderbolt working, but I still get that silly error message when I start my computer saying that Thunderbolt software doesn?™t run anymore and can be safely uninstalled. I simply ignore that message and then everything seems to work fine.

Very poor quality service from ASROCK, very unserious. Next time will buy from another vendor.

Hey there !

Well thanks In fact I replied to you immediately as I saw your message because I did myself wait a loooooooong time without any reply to my posts and would not want the same thing happen to you

I think you should open a support ticket as well, the more they get them the more possible they?™ll move themselves to fix the problem I guess.

Don?™t hesitate to be rough on them. I told them that at that price point I was expecting another quality both of gear AND service. ;)
