FreeFileSync Forum

As seen on another post, downloaded again version 10.22 and there is no popup on startup, but "* FreeFileSync Unknown is available! *" still appears no the menu.

On my Mac since version 10.21 that Freefilesync shows an error message on start, attached.
This happens on both an iMac on High Sierra 10.13.6 and a MacBook on Catalina 10.15.3.
Pressing cancel the sw works fine.
