Hello guys. I’m fairly new to this but when I was on Mojave, everything worked perfect. Now after the update I need to plug the HDMI in the Mac Mini in order for it to boot windows10. I have never had any problem before and I installed windows via bootcamp partition normally. 

Hardware:

 

Software

  • Windows 10, latest public version
  • Most up-to-date Thunderbolt 3 drivers
  • Most up-to-date nvidia drivers.

 

Problem:

  • After the update, I now need to plug an HDMI cable in the mac mini in order for it to boot up and detect eGPU. This never had happened in Mojave. Is there a way to downgrade 

 

Update: it seems that if I turn off the razer core x and wait for windows to boot and then turn it on it works. It seems the problem is booting windows while the core x on is what trigger the freeze.

Turing graphics cards have firmware compatibility issues with Macs. Prior to Catalina, your 2018 Mac mini was probably running an older firmware that worked with the GTX 1660 Ti. Catalina updated the Mac mini firmware and now GTX 1660 Ti eGPU connected at boot causes the boot hang.

Thank you so much for the help. So there’s nothing to be done but waiting right?

@swezz_beats Unfortunately it's nothing we can do. I don't think Apple will make it easier for Nvidia.
