Little Snitch 4.0.6 Posted 3/23/2018 at 18:54 UTC in Mac by gnye@amdesign.net | Permalink | Tweet Little Snitch 4.0.6 makes Silent Mode actually silent again. Starting in Little Snitch 4.0.5, processes with certain code signature issues caused Connection Alerts to appear even during Silent Mode. These appeared in more situations than we originally intended, though, so we redesigned how this works. Now, no Connection Alerts will appear during Silent Mode (as it was before Little Snitch 4.0.5), but you may see a notification in the top-right corner of the screen about connections being denied due to code signature issues.
