This also happened to me. The files have the .pdf file extension, but they show as Illustrator files and open in Illustrator. I just updated Mojave to 10.14.4 and exported from the same InDesign file and it worked fine. Although other InDesign files exported PDFs just fine even before this update so I don't think Mojave is the problem.Cathy supported this idea ·
