RAW files not downloading
I have a Nikon Z6II and a MacBook Pro. I can't for the life of me figure out how to download my RAW files onto the computer. I have updated to Big Sur. This is where the problem started. Before, I downloaded onto Nikon Capture NX-D and then converted to Photos. Now I can't even do that. Nikon says it's not their equipment. I have tried opening the files from the SD card on an older computer and that doesn't work either. In Photos I just get a grey blanked out thumbnail. I have never had this problem before with RAW files in an older Nikon.
