Storyline Mac Os off line browser delivery

Hello heroes,

I am having serious issues with the off line delivery of my Storyline project on Mac Os. 

The course features: 

• a drop-down locked menu within the Storyline interface;
• .pdf attachments through button triggers;
• the "print results" utility within the final slide of the embedded quiz;
• double-click trigger for interaction.
• quiz timer within the Storyline interface.

Due to the client's requirements, I must deliver the course on Mac iOS, exclusively off line and without

the Articulate Mobile App.

I tried (so hard) with three different browsers (all of which in their latest update), 

and following are the outcomes.

Chrome

- opening story.html

• Neither Pdfs nor "print results" work (I have already checked the settings, and they are ok).

- opening story_html5.html

• Quiz timer disappears
• Double-click does not work
• "Print results" work does not work

Firefox

- opening story.html

• Neither Pdfs nor "print results" work  (and Firefox Built-in Pdf properly running).
• "Print results" work does not work

- opening story_html5.html

• Quiz timer disappears
• Double-click does not work

Safari

- opening story.html

• The drop-down menu is no longer locked!
• The "print results" utility does not work!

- opening story_html5.html

• Double-click does not work, even if I read there http://www.articulate.com/support/kb_article.php?product=st1&id=1568gg1ayot2 that only Mobile Safari has this constraint.
• The "print results" utility does not work!
• The drop-down menu is no longer locked!

I don't know if this is "only" a matter of flash... but even with Html5 I encounter big issues, and this also affects ghraphics...

I really need help, because my client is not going to be understanding...

Which could be the solution to deliver this project off line within Mac Os???

Thank you,

Alessandro
