How to get mac version to dmg for amazon?

Amazon require a DMG file for Mac programs. I have windows 8.1. After exporting to a mac OSX format, how do I get it to get to a DMG? Is there a simple program to use or do you have to pay tons of money for a mac?

I think you should check some DVD Image creator tools, few tools like UltraISO, Magic ISO support DMG to ISO and ISO to DMG convertation.

You can try it like first create ISO using NERO, UltraISO, MagicISO and then convert it to DMG.

I am not sure it’s works or not, but you can try it, may it work for you…
