Gray exclamation mark in Photos (Sierra) after importing raw pictures from my camera Yesterday I had my first photo session with my new Fujifilm X-T2. Today, I inserted the SD card on my mac, opened Photos (Sierra) and saw all the pictures I took (raw). I proceeded with the import, and all seemed ok.

But even If I can see the thumbnails for all the pictures imported, when I open some of the photos I just get an exclamation mark.

I've tried importing/deleting multiple times, I've tried rotating,unrotating. Nothing. Apparently Photos doesn't like some of the pictures I took :(

Any suggestion?
The problem is your camera is too new! Apple Photos does not yet support RAW files from the  Fujifilm X-T2. Apple should release an update that will add this support, but I could not tell you when that might happen. For the full list of supported camera RAW formats, see this site.
