Hi Filip, I am also interested in porting a Win app to Mac. It is a C# .Net app. Could you please be more specific. What do you mean with portable model and builder pattern for view and new concrete class for each platform. That sounds like developing a new program, not porting an old one.

The Builder Pattern (http://en.wikipedia.org/wiki/Builder_pattern) is a simple design pattern that enables you to write programs without knowing in advance what classes you will be using. All you will do is program against an interface. But porting C# to mac actually means rewriting all C#
