A firewall protects your computer against unwanted guests from the Internet. But who protects your private data from being sent out? Little Snitch does!
Little Snitch informs you whenever a program attempts to establish an outgoing Internet connection. You can then choose to allow or deny this connection, or define a rule how to handle similar, future connection attempts. This reliably prevents private data from being sent out without your knowledge. Little Snitch runs inconspicuously in the background and it can also detect network related activity of viruses, trojans and other malware.
What is new in this release:
- Refined some icons to better match the look of OS X Yosemite.
- When using OS X Mavericks (10.9) or later, Little Snitch Agent, Network Monitor, and Configuration should not cause the discrete GPU ("High Performance GPU") to be activated anymore, especially on Mid 2010 MacBook Pro.
- Fixed: In Little Snitch Configuration, when pressing while no rule was selected, the last rule was selected.
- Fixed spontaneous horizontal scrolling of text in the Connection Inspector window of Network Monitor.
- Fixed: Closing the Connection Inspector window did not preserve its position on screen.
What is new in version 22.214.171.12433:
- Fixed an issue causing a first time installation of Little Snitch to hang under rare circumstances when attempting to restart the computer.
- Refined appearance in configuration UI to better match the look of OS X Yosemite.
- Improved user experience when a connection attempt was automatically confirmed after a timeout.
- Fixed an issue in Network Monitor causing the destination of a connection to be wrongly shown as "0 Servers".
- Improved compatibility with Xcode Server.
What is new in version 126.96.36.19931:
- Greatly improved support for iOS Simulator apps in Connection Alerts, Network Monitor and Configuration. Read our blog post for details on how iOS Simulator apps are now handled in Little Snitch.
- Added support for showing iOS App Extension icons.
- Improved handling of via connections:
- Connection alerts now show a cancel button if either the parent or the via process is terminated.
- Until Quit rules are now valid until both the parent process and via process have terminated.
- OS X Yosemite changed how incoming ssh connections are handled. Incoming connections are no longer handled by sshd directly but instead by launchd. On OS X Yosemite, this version of Little Snitch automatically converts existing rules to ensure incoming SSH connections work as expected.
- Little Snitch menubar item no longer occupies space when disabled.
- Fixed: The process owner in Network Monitor Snapshots was "root" instead of the actual user in many cases. Snapshots now store the user's names and show them correctly.
- Software update checks are now using HTTPS. We will gradually enable HTTPS for all other connections to our servers in the near future.
What is new in version 3.4.2:
- Fixed: Connection alert occasionally no longer appears after using the Research Assistant.
- Updating Little Snitch prior to upgrading to OS X Yosemite is recommended.
