I can't view Sony a7r IV raw files thumbnails
I have an iMac Pro 2017 and a late 2019 MBP both on macOS 10.15.4 and I can't see the thumbnail previews of the .arw files from Sony a7r IV from the finder. I have no problem in seeing the thumbnail previews from Sony a7R III, so the issue is camera related. The Sony a7r IV is a supported camera on Catalina though, so I really don't know what to do.
Any help would be appreciated
Best regards
iMac Pro, macOS 10.15
