thanks @davstrom for the helpful post. this is exactly the information i was looking for about the Kinlde Previewer and the location of KindleGen. You don't need to copy the app's Contents Folder. you can access KindleGen directly from within the Previewer. 1. open Package Content from Kindle Previewer App in Finder 2. navigate to "/Applications/Kindle Previewer 3.app/Contents/lib/fc/bin" 3. click in Storyist to choose the location of KindleGen 4. drag the kindlegen file from finder into the storyist-file-dialog 5. mac os changes the location automaticly to the folder inside from Kindle Previewer.
