I disagree with the chosen directory for Mac. According to [Apple](https://developer.apple.com/library/mac/documentation/FileManagement/Conceptual/FileSystemProgrammingGuide/FileSystemOverview/FileSystemOverview.html#//apple_ref/doc/uid/TP40010672-CH2-SW1) and [node-webkit](https://gentlenode.com/journal/node-webkit-1-complete-cheatsheet/26), the correct path is **~/Library/Application Support**  or **~/Library/Caches** This will require a change in the Simulator as well. @KristinaKoeva @bkulov @ligaz  @zahhak @nedyalkov your opinion?
