@guillem_g, there is no need to reinstall the OS. All you need to do is follow the instructions for setting up Kryptonite but inject the linked kernel extension as @itsage did here: https://egpu.io/forums/mac-setup/kryptonite-tb1-2-mac-egpu-support-with-filevault-sip-and-art-enabled/paged/7/#post-96272

Of course if it’s your primary system/workstation and if you don’t wish to try, that’s completely understandable. Just letting you know there’s an option if you fancy testing.

@pavel, ASRock RX 6800 XT Taichi gets my vote. It fits the Mantiz Saturn Pro like a glove once you remove the angled bracket as seen in my build.

Not sure if you have tried this yet?  Works for me on bootcamp with Razer X Chroma + RX 6900 XT:

@mike_deggs, Does it work without Boot Camp on macOS?

@mike_deggs, thanks.

It does work for me as well in Bootcamp. No native support for RX6700XT on MacOS yet. I'm running 11.5 beta 3 and no luck.

@itsage, I've seen a good build. Why didn't you buy 6900 because it is more productive?

Yes, I have the 6900 XT working in native Mac OS as well. It’s worked in 11.4 and also in 12 beta 1.

Cannot speak to 6700 series card.
