On Silicon I can guarantee that the Cosmo Libc emacs prebuilt binary will have zero trouble launching a llamafile process. https://cosmo.zip/pub/cosmos/bin/emacs You can also edit the `call-process` call so it launches `ape llamafile ...` rather than `llamafile ...` where the native ape interpreter can be compiled by wgetting https://raw.githubusercontent.com/jart/cosmopolitan/master/a... and running `cc -o ape ape-m1.c` and then sudo mv'ing it to /usr/local/bin/ape

Well, I'm really attached to my emacs-mac binaries, which get a lot of details right — but the "ape" approach worked fine, thanks!
