I am having the same problem as reported here: https://emacs.stackexchange.com/questions/66593/how-to-open-a-link-to-a-folder-file-in-finder-not-dired 

I copy paste:

I used to be able to create links with open-insert-link pointing to folders or files. When I clicked on them, I would be redirected to Finder. Lately, they are shown within Dired. How to control this behaviour? When I use either [[file:/users/Shared]] or [[file+emacs:/users/Shared]], and click on them, I get the dired buffer, not the Finder app. 

Thanks!
G.M.
