Hello all, I have a simple path in org-mode /Users/nate/some_pptx.pptx When I press C-c C-o it opens the file in binary mode in Emacs. A path to a PDF will actually open the file with the associated program: /Users/nate/some_png.png -> Opens in Preview when I press C-c C-o How can I get emacs / org to open pptx files in the same fashion as if I had double-clicked using Finder on Mac? Thanks, --Nate
