Hello @pastrychef !I only tested on OpenCore 0.6.3 for now.
Go to config.plist > Kernel > Quirks and enable DisableIoMapper. If you don't do this, ethernet and Wi-Fi will be broken.

I'll try to install Big Sur on another SSD today and keep my Catalina 10.15.6 install on actual. I think about enable DisableIOMapper on my actual EFI partition. My question is :
Does enable DisableIoMapper will affects my Catalina partition ? like breaking ethernet on Catalina but make ethernet working on Big Sur.
