Glad to know it's not just me, anyway guys we can stay relatively calm because I found in a dutch forum a buddy with a real mac pro having the exact same issue like us, so it's a 11.1 bug and not an hack problem. I suppose we just have to wait them to fix in next update, even if I would remember everyone that VII is not offically supported by Apple neither egpus boxes manufacturer (like sonnet or razer) for macOS. This gives me a bit of scare, considering the fact Apple could just stop supporting, even unofficialy, the Radeon VII (which, hopefully, is somehow close to the Pro Vega II they ship in MPX module).
