Slight nitpick, Nix does support more architectures, but those are the ones with prebuilt packages. Compiling say 32 bit ARM is quite feasible, takes roughly a day for a full OS image.

Guix builds binaries for

    - x86_64-linux
    - i686-linux
    - aarch64-linux
    - powerpc64le-linux
    - i586-gnu

> Perhaps some day this will also be possible for Guix, but I don't think it fits the ideology of Guix since MacOS isn't free (not as in beer).

I just wanna note here that the hesitation to invest in macOS support in the Guix development community is technical as well as ideological. macOS is a difficult platform to support for third-party package managers, and developer interest in macOS support is a difficulty within the Nix community, too. There's a lot of breakage on major macOS upgrades as well as some fundamental portability and hermeticity problems on the platform.

That said, (as an outsider) I think it would be awesome if Guix ran on macOS, just like it's ultimately a good thing for the world and for GNU that Emacs runs pretty well on macOS.

I've had some luck in building it on MacOS with brew, however, the investment of learning MacOS dynamic linker is too costly at the moment, and it seems to be a blocking issue right now
