The computer under discussion (2011 Intel Core i7 iMac) has a 64 bit architecture and Mac OS 10.13 is 64 bit (Mac OS has had a 64 bit option since 10.6 and 10.8 removed the 32 bit kernel).
This definitely isn’t likely to be a 64/32bit issue - I think that’s some kind of confusion. However, is it possible that the build process for the newest lilypond release discussed sets a minimum Mac OS of higher than 10.13? Mac OS settings for this compiler variable are hard limits, even if the code could compile/run on a lower OS. Something about 10.13 would seem a little conservative for an open-source project of this nature. I had a super-quick skim of the source, and beyond seeing that it looks like a GNU make build system, I could only see that it was likely too complex for me to be able to easily figure out what would be happening here quickly. If nothing is being set for a minimum OS then it will (I believe) default to the OS it is being compiled on - that might be the source of the issue.
