Some apps work fine, some not (exec /usr/local/bin/docker-entrypoint.sh: exec format error)

Hi,

I’m entirely new to self hosting and really only tried it cause of all the great reviews of Umbrel OS on YouTube

I’m encountering exec /usr/local/bin/docker-entrypoint.sh: exec format error when running some apps (e.g. Immich and Booklore), while some apps work fine (e.g. Plex and Tailscale). I understand this error is due to CPU architecture between x86-64 and AMD, but why can some apps run and not others? For reference, I am using an old Intel based 2012 Mac Mini

Thank you
