error msg when dragging photos to folder
I'm trying to copy some 7000+ images from Photos for Mac into a Finder folder. Most were copied but a fair number triggered an unusual error message. The gist of the message is that the photos couldn't be exported because I don't have permission. Please see screenshot for complete message.
Can anyone shed light on this and provide advice on how to correct this error?
Thank you,
