Hi, have the impression https://github.com/nextcloud/all-in-one only allows installation on linux?
Is there an easy way to installe the AIO image on MacOS and if so how ?
Hello 
,
in theory Nextcloud AIO should support other OS than Linux, too, but it was never tested there. You could try to install Docker Desktop though and run the mentioned command (docker run…) after you’ve installed Docker.
Docker Desktop is available here: https://docs.docker.com/desktop/mac/install/
Please report back if there are issues. Thanks! 
ummm… NC AIO shoud work with docker.
So it seemingly depends upon how docker itself is integrated into your OS.
Just as an update to this: we have some docs on this available in the meantime: GitHub - nextcloud/all-in-one: Nextcloud AIO stands for Nextcloud All In One and provides easy deployment and maintenance with most features included in this one Nextcloud instance.
