Hey all I have an experimental Docker/Podman build here, which you can take for a spin, it works well for me, I don't have any macOS devices to test on yet though, LMK.
Docker tarball hosted on 2 sites: https://limewire.com/d/IHVnx#Pz9q6EwDwL https://filebin.net/gevqik62yzwfxa8u/maak-docker.tar.gz
Once you downloaded this tarball, you can import it with docker load < my.tar.gz
Installing via Guix will always remain more convenient and powerful but docker/podman will work for cross-platform pretty good. Say for example you have a maak file with a task serve, at /home/joe/hacking/hygguile/maak.scm , you could run it as so:
docker container run -v /home/joe:/home/joe localhost/maak:latest maak -f /home/joe/hacking/hygguile/maak.scm serve
