The desktop application part of Multi-Terr was developed using MS Access and Microsoft has not yet released an ACCESS application for MAC. Therefore we do not officially support Multi-Terr Desktop on a MAC, although some have made it work by using applications to simulate Windows 10 or using dual boot (since these setup have not been tested by our team, we do not officially support them).
But Multi-Terr Web App is supported on all electronic devices (Apple, Android, Windows)
