I’m currently using a late-2012 27” iMac with macOS Catalina 10.15.7, but this
can’t be upgraded to macOS Big Sur, and a recent whiff of overheated
circuit-board when I leant over the back of my monitor prompted me to order a
replacement which is due to arrive today.
I want to make an orderly transition of all my applications and data to the new
computer, but would be happy to try a quick installation of lilypond on a
virgin machine running MacOS 11 if that would help you.
