I changed iPhone's and with the new one the photos get imported successfully - as shown below. The weird thing is I can not get the images to display except in thumbnails. With the prior phone I would double click on an image and it would be shown in a large size view.
So what am I missing now in how to view the individual photos in larger resolution?
Update Found this Apple provided documentation https://support.apple.com/guide/photos/browse-and-view-photos-pht56eafa987/mac :
However double-clicking or pressing return just puts that blue check-mark: does not work.
Update An answer mentioned to import the photos. Well they are already imported: I had double checked and even went into the
Library on disk and was able to open the photo from there.. But that's a really awkward/long-ish process..
