XnView as default viewer on Mac

[dabayer]

Hi,
I can't manage to set up XnView MP as the default image viewer on my Mac.
I can select an image with right-click-open with the XN but even if I check the box “always open” it does not work.
For example, the image format is CR3. XNView is not even suggested as a program here, you still have to check the "All programs" box.

with JPG or PNG?
