Snap N’Go is an application which runs only on Android & Bada devices from Samsung and because it has been released by Samsung company and it’s a feature available to these phones only, you won’t see it released for Mac or something that has to do with Apple because of the rivality between these two companies ,so basically, it’s not Mac friendly. The client runs only on Windows operating systems.
If you really want it to work under Mac environment then install Parallels Desktop and emulate a Windows machine and install it like any other Windows application and maybe it will work because the application also installs drivers which are compatible with Windows OSes.
