Just spent the last 10 minutes figuring out why I had no internet connection after upgrading to macOS Sonoma. Little Snitch seems to have been the culprit. Has anyone else encountered this problem? 

 @b902f84f negative, upgraded to Sonoma earlier this week with no LittleSnitch issue. I did see there's an update pending to LS yesterday on my macbook, but have not installed it yet.
