Acrobat Reference in Excel VBA on Mac (not PC)

I am having troubles with setting the reference to Adobe Acrobat from Excel VBA which is running on a Mac. 

Let me provide a bit of background:

I have been programming VBA within Windows in Visual Studio, Access and Excel for a couple of decades.  So I am very comfortable with both Windows and VBA.  Recently, thanks to some assistance from one of the forum questions I posted, I was able to beginning writing an Excel program which interacted with the various forms I created with Adobe Acrobat Pro DC for my windows laptop to retrieve information from the form to various tabs within the Excel workbook, my first venture with Excel/Adobe interaction.

I was doing all of this for a friend.  Unfortunately, my friend has a Mac.  So now I am trying to get this Excel workbook to work on his Mac with the loaded Office.  However, I have run into a big problem with regards to the reference to Adobe Acrobat.

He also has installed Adobe Acrobat Pro DC on his Mac (he has even tried to make minor changes to a few forms).  Since he is not technical savy, he has no idea what I am talking about with regards to trying to solve the "Adobe Acrobat 10.0 Type Library" reference error.  And since I don't know my way around a Mac, I don't know where to look or what to look for.

So it boils down to the following:

-I have an Excel macro that works successfully on Windows that references Adobe Acrobat Pro DC (reference solved without my assistance)

-I have moved that same Excel macro workbook to a Mac

-Adobe Acrobat Pro DC is installed on both the Windows laptop as well as the Mac

-The "Adobe Acrobat 10.0 Type Library" reference on the Mac is unresolved and I have no idea how to resolve it as I am not a Mac user.

So in some ways, this is a Mac vs PC question but it is trying to solve the Adobe reference.  So I hope someone here might be able to provide some guidance or suggestions.

Thanks in advance,

Nick
