Image Capture error 9934
I kept getting error 9934 from Image Capture, even after resorting to things like "chmod 777 ~/Pictures", so while the permissions can be an issue its not the only source of this error, I was guessing that file locks can also trigger this error, which can be cleared by re-booting / re-starting a unix OS like macOS, and sure enough that solved the problem for me. HTH.
