I've been trying to downgrade to Catalina from Big Sur for 2 days now on a brand new machine that came with Big Sur. I've tried numerous ways. Currently, I'm running into 2 issues. (Ignore the wrong screen resolution in the photos below - this seems to be an effect while in Recovery Mode only, most likely related to the KVM we use in our production studio setup.)
1) I can't erase the container. I click the Erase button, it turns blue when I click it, but nothing happens.
2) In the Catalina installer, there's no other disk option besides the USB stick. Maybe that's because I can't erase the container.
Any help would be appreciated! Thanks in advance!
