Where can I get Mac OS Goodway planner?
The official website where GoodWay is hosted displays the following error: "503 Service Unavailable", which means it's impossible to acquire any data about it and its compatibility.
However, on Mac OS you can install an emulator called Wine Bottler. Wine Bottler allows you to run Windows applications without the need to install an operating system.
Download Wine Bottler: http://winebottler.kronenberg.org/
