Framemaker Alternatives for Mac

I would like to do some publishing with the option to export the final product to multiple formats.

Adobe Framemaker seems appealing since it easily supports output to many desirable formats including:

  • PDF
  • Epub
  • Kindle
  • Responsive HTML5
  • iOS App
  • Android App

The downside is that Framemaker is not available for Windows.

I can use Framemaker with Parallels if needed, though I would prefer a native Mac if there were one available with similar capabilities.

Does anyone know of a Mac writing/publishing app which supports the above output formats?
