No idea where to ask about this. I know there was some kind of change with Dropbox and that Dropbox would no longer back up my Apple Photos library (thanks for that, Dropbox). I just tried to open my Photos app on my MacBook Pro and it told me that Dropbox needed to move my photos to a new directory. I created a new directory and its empty. How do I get my photos off of Dropbox and on to my mac? I had no idea Dropbox would do this.
