I have it working here on both intel and M1 machines.
I found you have to make enough noise (https://forum.bfddrums.com/t/under-review-bfd-3-4-3-7-macos-crash-on-start-resolved) to get their attention, for someone @ bfd to DM a functional Installer, labeled as “3.4.4.2”.
Def not optimized for M1, but functional…
good luck,
