Interesting, based on this and other replies, it sounds like Photos App should have an option to select what to import? i.e. RAW or jpg, but not both.

It sounds like Photos App can have issues trying to import both at the same time?

As I said in my blog post, it imports both and combines them in the UI. Also as I said in my blog post, I switched to shooting only in raw, and it still exhibited file corruption.
