On my Mac - running OSx 11.4 (BigSur) - OCPN always triggers a popup requesting me to grant permission for screenshots on launch. Every time I launch the app.
"OpenCPN.app would like to record
this computer's screen"
When I click "Open System Preferences" it brings me to the system preferences app - there is a list of apps which have been granted permission to record
contents of the screen
, OCPN is listed there with a checkmark, so it already has the permission it is asking for.
I've tried unchecking it and re-checking it, in various sequences.
Note: This was happening before I upgraded to 5.6.0 which was just last week. I was hoping that the upgrade might fix this, it's been happening for months, but, I've just been ignoring it till now.
I have not yet tried to uninstall (delete) OCPN completely and re-install it. I am worried I would lose some or all of my configuration settings, chart groups, connections, etc., etc. -- I am sure there is a procedure for doing this and restoring prefs and settings. I will do it if there is some reason to believe it will help, if that is the collective wisdom of the OCPN experts.
