  • Little Snitch Mini
    I'm using radio silence for years and it is awesome :) - Source: Hacker News / 3 months ago
  • Do You Use A 3rd Party Firewall App On Your Mac ?
    Forgot to mention Radio Silence (commercial), seen by many as an easier introduction vs Little Snitch. Source: 7 months ago
  • A little help
    Sorry for the late reply. I use Lulu which should be enough, but I also simultaneously use Radio Silence to be safe. Source: 11 months ago
  • Little Snitch vs TripMode 3 - monitoring my web traffic
    Little Snitch (LS) is considered by many to be the gold standard. The aforementioned Lulu has a good reputation. The app Hands Off! Appears to be no longer developed (site offline). Then there's Radio Silence that may well fit your needs. Finally, one or more apps by Murus may be of interest but AFAIK these are not easy to configure and may be overkill for the average Mac user. I'm not familiar with TripMode. Source: over 1 year ago

  • Is it still true that Bear(note taking app) tries to connect to copied URLs?
    When you copy and paste a link into, the application tries to connect to the URL to identify the Open Graph metadata, if there is any, and then embeds the relevant parts (title, description, image, etc.) into the document you are editing. Nothing malicious, but if you care about your privacy, then consider blocking all outgoing connections using a firewall like Little Snitch or Radio Silence. Source: almost 2 years ago
  • Can I force-deny internet access to the Apple-related tasks that firewalls (like Little Snitch) are allowing by default?
    Radio Silence (not free, but not expensive). Source: about 2 years ago
