I just upgraded to MacOS 10.15 and am experiencing some pain. The faithful org-download-screenshot from https://github.com/abo-abo/org-download stopped working.
Instead of capturing a window or selection, it just copied the background. This - forbidding screen capture - is considered a security feature. After some trial-and-error I managed to get org-download-screenshot working again by editing System Preferences: - Allowing Ruby access to Screen Record - Allowing Emacs to run software locally that does not meet the system's security policy (this is under Developer Tools). FWIW, I set `org-download-screenshot-method' to "/usr/sbin/screencapture -s %s" If someone can advise me on a better way to enable org-download-screenshot on Catalina, I would appreciate your advice. Best, Chuck
