I'm new to the forum.
I have a Sony a9 and last week I was watching a YouTube video about settings and made a couple of changes although I don't remember which ones though they seemed minor.
I already had changed numerous settings from the default ones over past 6 months with no issues.
Last week after I made the most recent setting changes, when I tried to upload the RAW files to my iMAC, every RAW file was an exclamation mark inside a triangle instead of an image for the files after I changed the settings but the RAW files that were on the card before I made the changes all uploaded correctly. The mac 'Get Info' didn't recognize the camera or the settings and the RAW file sizes were half of normal. The thumbnails in the iMAC's 'Photos' app looked file until they were uploaded.
As a test, I took some new photos using another RAW card and uploaded them and the same thing happened on this same mac and another one so it seems like it is a setting in the camera and not the computers or the cards but I can't figure out what it is. I wrote Sony and they said there is nothing that I could do in the camera to make that happen. I'm not sure that I agree.
I'm about the reset the camera to the factory settings, if that's even possible, but wanted to ask here if anyone has had this happen to them or might know what happened? The jpgs all uploaded correctly.
I ended up using the Sony Image Edge Desktop program and it let me turn the exclamation point in a triangle images into TiFF files. That makes it even more confusing for me to understand what is going on.
Thank you in advance for any help,
