As the Mac port supports image types the Image I/O framework can
handle, HEIC images can be displayed on macOS 10.15 and later.  You
need the following setting mentioned in the info node "Mac Images":

     (when (and (image-type-available-p 'image-io)
                (not (boundp 'imagemagick-render-type)))
        ;; Image I/O is used as a fallback of ImageMagick.
        (setq imagemagick-enabled-types t)
        (setq imagemagick-types-inhibit
              (cons 'XML (delq 'PDF imagemagick-types-inhibit)))
        (imagemagick-register-types))
