Unless I’m missing something.. you can not downgrade from a Mac (in my case, 27″ iMac) that came with Catalina preinstalled.. not like in previous OS versions.. it will not allow the reboot/dualboot.. I’ve tried, with bootable Mojave, High Sierra, El Capitan and even Snow leopard drives.. even was with Apple on the phone doing it…wiped HD clean, changed the formats, etc, etc, etc,… the only way is to go deep in the firmware, wiping it, which will void your warranty..
