I want to change fonts but get message "no available system font"

Question

I am trying to edit a PDF flyer created by another party.  Using Acrobat Pro on Mac OSX.  I select "edit document text" and then try to delete or change the text and get the message. "all or part of the selection has no available system font You cannot add or delete text using the currently selected font"
I don't see any font format bar or other method of changing the font.
Is there a way to work this?

Over at the AUC's "Acrobat Answers" Karl Kremer replied to a similar question.
In part he wrote:
"I assume you want to edit content in a PDF file, and you cannot do that because you don't have the font installed that is used in that file. That is the way Acrobat works: You need to have the font that is used in your document installed on your local computer in order to make changes to text that uses that font. There is no way around that. You will have to find out what font is used for the text you need to edit, and then acquire that font (and that usually means to purchase that font, unless you are a subscriber to e.g. CC and that font is available via TypeKit).
Another option is to select all the text and change that text to a different but similar font. You again can only use a font that is available on your computer as the target font. But once you've done that, you should be able to edit your document.
You change the font by selecting Tools>Content Editing>Edit Text & Images, then you select the text you want to change, and your target font." 
Be well...
