I had a memory of somebody else reporting a similar problem, and it turned out that they had too many folders on their desktop. Once they cleaned up, it came back. However, I just went searching and found the discussion, and that person was on a PC, not a Mac. So it probably doesn't apply.

Please don't wait too long to jump into the Bridge Class. It's really important that we start to establish your whole workflow.
Hell no, it's definitely NOT smart.
First of all, please explain why you want to do this nonsense at all. Why do you think you need copies?
Choose your explanation carefully, because my bitch-slapping hand is poised.
Well, my first question would be - do those modes apply to raw files?
I'm afraid I don't know anything about drone cameras. I'm just thinking of other cameras, which have various modes that only apply to jpeg files, you know?
Terrific.
No, it doesn't matter. I mean, I don't recommend it, because of backups, but it's not a "problem" at all.
There's no need to be uncertain. Just check! Open Bridge, navigate to the folder of files, and see what you can see.
