Files could not be copied to the backup location
I'm working on a new MacBook Pro and trying to create an Import preset so that file copies get written to an external SanDisk SSD. On starting the import, LrC recognizes the folder, but when executing the import I get a message "The files could not be copied to the backup location." I checked the SanDisk and saw the file had not been copied. To ensure that there wasn't a SanDisk failure, I copied another file from my desktop computer into the same folder and was able to find it with Mac Finder. Not sure what to do next.
