Thanks, but what I need to work is Capture One...
Do you mean that Capture One will not load a Fuji file on your Mac?
Capture One loads the files just fine when I connect the SD card to the Mac via card reader. But if I connect the x100v to the Mac, with the x100v set in "Storage Mode", Capture One does not load the images.
The fact is that the camera implements the "camera interface" to a Mac, which is useful only to the Mac app (Image Capture I think it's called), but does not implement the true "storage interface" that is needed to make the content of the SD card accessible via finder etc.
But again, if you remove the SD card from the x100v, and connect the SD card to the Mac, then everything is fine.
It's just a bad implementation compared e.g. to my Olympus E-M1, where I can directly browse and load the images with the Olympus connected via a USB-C cable to the Mac.
It would have been nice to be able to both charge and transfer the images, at the same time.
