PROHIBITORY AFTER UNIBEAST

Been trying to fresh install Catalina but no luck. Followed the setup guide all the way with BIOS and used Unibeast. I keep getting the Do No Enter sign situation after apple shows up. What am I doing wrong?

You're calling it a Stop sign, it's not :

It's not a Do No Enter sign either.

Search for 'prohibitory symbol' or 'still waiting for root device'.

I never said it was a Stop Sign but that is the symbol. I'm seeing that after the clover screen appears, then apple, and 3 seconds later i get that symbol.

Important Update: June 2023 From Big Sur 11.3 on the built-in OpenCore XhciPortLimit quirk no-longer worked as described. This became a known "bug", though in reality it was Apple changing their internal code, making a simple "peek and poke" to keep it operating, a difficult task. However, with...
