I can no longer import photos from a card reader or from the Mac Library to Lightroom 5. This was never an issue until now. The Mac software is up to date and nothing has been manually changed. Is this common to anyone else?
RAW files yes. The card reader is an old usb so I was using it with a USB C convertor. It can neither import photos from the desktop. The import bar indicator in the top left does not move and when I quit the message says no photos to import.
I can export a photo onto my desktop but that is it.
You say "The Mac software is up to date" (I really hate it when people say things like 'up to date' or 'latest version' instead of giving the version number) and that may actually be the problem. Does that mean you are running MacOSX Catalina? If so, check that you have given Lightroom permissions to access the desktop folder or removable volumes.
