Without knowing more about this, try this.

1. Download and install the HTML packager again: Installation and setup for AEM Mobile tools
2. Double-click the .dmg file, and then drag the HTML Article Packager file into your Applications folder.
3. Add the main HTML file and its required assets to a folder. Name the main HTML file index.html.
4. Drag and drop the HTML folder onto the HTML Article Packager icon.
