I've searched all over the internet to no avail. Is there a visual studio Prism template pack for Visual Studio v7.0.1 for Mac? The closest I've seen to this template is for Xamarin Studio which is not compatible with the new Visual Studio.
No there is not currently a template pack available for VS4Mac. It is something that is being discussed, and will likely get visited once we get the v7.0 preview released. You can track the issue here.
While it's not exactly something that's currently integrated with VS or VS4Mac you can use the dotnet templates available here. They do work cross platform, currently from the dotnet cli, but the VS team is working on integration for all of the templates for both VS2017 and VS4Mac.
