Hi Francesco, I have looked into this and wine is not needed. However, there are still some hurdles. I will list the steps so that it is as straightforward as can be (or as much as it can be from me :-) :
1. Install the GHydraulics plugin. This plugin actually contains command line binaries of epanet for Linux, Win, and Mac; though, it is actually against plugin policy to distribute pre-compiled binaries with plugins through the official QGIS repository. Nonetheless, it is a good thing for you and other Mac users. :-) This means GHydraulics actually works right out-of-the-box. There is a bug in one of the sources, though. In ~/.qgis2/python/plugins/ghydraulic/GHydraulicsModelMaker.py: Change ALL instances of QgsMapLayerRegistry().instance().mapLayers() to QgsMapLayerRegistry.instance().mapLayers() I'll be reporting this upstream to http://epanet.de/ NOTE: some of the reporting from the plugin is actually sent to the Log Messages Panel. Choose 'View -> Panels -> Log Messages' to ensure it is visible. See also: http://epanet.de/ghydraulics/index.html http://sdteffen.blogspot.com/search/label/GHydraulics 2. Since you already have an epanet2d command line binary for Mac, you can just use its path for the configuration of the 'qgis_epanet' plugin: /Users/<user>/.qgis2/python/plugins/ghydraulic/bin/osx/epanet2d NOTE: replace <user> with your short user name. There is some sample data to play with available in the github.com repository: https://github.com/Oslandia/qgis-epanet#testing I did have an issue when running a simulation, due to a missing Hydraulics file (could not resolve). 3. I think I will add epanet command line utilities to OSGeo4Mac, so this is simpler to set up.
