Huh? OSM is not a maps app. And this is completely unrelated to browser and OS support. OSM is a maps repository.
You can browse the maps of the “repository” via openstreetmap.org in your browser. There are multiple apps using the “repository”, like Gnome Maps for Linux or OsmAnd on Android… And many other apps: https://wiki.openstreetmap.org/wiki/Software/Desktop
What exactly is the problem?
