So is checking the architecture, and failing because the OS 
reports it as arm64.

case $(uname -m) in
     x86_64|amd64) ARCH=x86_64; MODEL=64;;
     aarch64) ARCH=aarch64; MODEL=64;;
     i*86) ARCH=x86; MODEL=32;;
         fatal "Unsupported Arch $(uname -m)"

You could change the line that starts with `aarch64` to `aarch64|arm64`

That might work. I'm not sure, because really you want x86_64 for dmd 
(there is no aarch64 or arm64 build of dmd).

Have you tried using the dmg package?
