A beautiful new design, improved traffic statistics, a brand new command line interface, simplified Drag and Drop installation and the seamless compatibility with the latest versions of macOS are setting Little Snitch 5 apart from its predecessor.
Redesigned Filter Engine and User Interface
The main focus in the development of Little Snitch 5 was on the integration of the new network filter technologies introduced by Apple in macOS Big Sur. The underlying filter engine was re-built from ground up to replace the previous kernel extension based approach which is no longer supported by macOS.
Furthermore, Little Snitch was adapted to the new, elegant design language of the operating system with great attention to detail. New design features, like a prominent search bar and a newly structured sidebar go beyond aesthetic choice and add a level of simplicity and intuitiveness to the user experience.
Drag and Drop Installation
The simplified Drag and Drop installation has been eagerly awaited by many users. Now it’s no longer necessary to restart the computer in order to install or update Little Snitch.
Improved Traffic Monitoring
Little Snitch now captures connection information efficiently in the background. It no longer requires the Network Monitor application to be running in order to collect this information, resulting in reduced memory and CPU consumption.
The improved monitoring system is now capable of holding traffic information from up to a whole year, instead of only the last hour as before.
Command Line Interface
System administrators now have the ability to configure a variety of program settings via a command line interface, making Little Snitch scriptable for the very first time.
This interface now also offers the possibility to report network connections in a log-based format for detailed and versatile traffic analysis.
