I've restructured my SSDs a bit so that with one I can try out BigSur , like be adventures csrutil and break my head , make it bleed , see the problems etc.
The other SSD is for stability, currently has Catalina.
I've got two EFI folders for each of the SSDs that have BigSur and Catalina which are carbon copies except that they have different SerialNumber , MLB, System UUID. Everything seems to be working fine on both drives but I just wanted to ask here if anyone has as similar set up and what they did. Is there a mini guide or any recommendations that I could follow use ?
You don't need different Serial Number, UUID etc. The one EFI can boot both Big Sur and Catalina. Mine boots Catalina, Big Sur release (11.0.1) and Big Sur Beta (11.1), all on different NVMe drives, all using the same SN/UUID/MLB.
