Mac OS Elements organizer can't watch network folder

Am I doing something wrong or does organizer not support network folders on mac os for watch folders ? I can add pictures from a network folder but can't add that folder to the watch folder of organizer

I am not a Mac user but there has been a number of old posts on that subject. The answers have always been negative, unless someting has changed recently. On the other hand I am not sure you can store your catalog folders on the network on Macs, I believe you should only store media files.

I don't like nor trust the watch folders service myself. However, don't forget that if you issue a 'Get photos from files and folders from one folder you want to watch, you get the same result since only new files are found and already catalogued files are skipped. I prefer issuing that command myself at the right time rather than relying on background processes I can't control.
