I don't know if this is useful to you. I haven't tried to install MIT Scheme directly on macOS. Instead, I'm using the sample project at [1] to run a linux VM with Fedora on macOS x86-64. I was able to install MIT Scheme and scmutils on the VM by following the instructions at [2][3][4][5] for CentOS. It appears to have succeeded but I haven't really worked with the system yet.

I haven't tried the instructions for ARM-based macOS at [6] because I'm still on Intel.

It's less convenient to run a VM than to run on macOS directly. But I prefer to sandbox "random" software that way, and some things support linux better than macOS.

(You have to install texinfo for the online documentation part of [5]. Skip the 'install-pdf' documentation target if you don't want to depend on tex/latex.)
