[O] org-download-screenshot on MacOS Catalina

[Berry, Charles]

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
