I'm afraid there's nothing much we can do.  IIUC, you copy the file from
a file manager, so Org expects clipboard to be something like

    Possible completions are:
    clipboard:x-special/gnome-copied-files
    primary:...

where clipboard:x-special/gnome-copied-files gives

    copy
    file:///home/viz/tmp/2-gnus_stipple.png

but given there's neither image/jpeg nor a special type like the above,
Org's yank-media copies the image/tiff data (the regexp used by Org
looks for mime-types that match the regexp "image/.*").
I am guessing clipboard:text/plain contains the link to the file, am I
right?  But this feels fragile to rely on.

What happens when you copy multiple images to the clipboard from the
file manager?  Is there a difference in yank-media-types' output?  What
if you copy a non-image file to the clipboard? Say a PDF file.

I don't have access to a Mac but if you can find documentation on how
Finder puts the relevant data in the clipboard, that would be useful.
[ In Linux, you expect the x-special/gnome-copied-files or somesuch
  TARGET.  ]

BTW, we might have similar problems in Windows too.  See this thread in
emacs-devel when yank-media was initially added:

Given the above, I hope you understand why this happens.

HTH.
