Are you referring to the desktop modeler? In that case Linux/Mac is not supported at all.

If you are referring to the web modeler, that should be accessable from any browser but it is optimized for usage with Google Chrome (https://docs.mendix.com/refguide/system-requirements).
The Mendix platform itself runs on java and therefor can be installed on any OS basically.
