New in Little Snitch 6

Blocklists

• Enhanced support for blocklists, similar to the features found in Little Snitch Mini.
• Conveniently choose from a curated list of blocklists, organized by topic (like Advertising, Tracking, Malware, etc.), allowing you to enable these blocklists with just a few mouse clicks.
• Automatic daily updates ensure that your blocklists are kept up to date when the maintainer adds new entries.
• Improved filtering performance when filtering network connections based on large blocklists.

DNS Encryption

• All DNS lookups can now be securely transmitted via encrypted connections to a DNS server of your choice, ensuring enhanced privacy when browsing the web.
• Configurable, system-wide DNS encryption.
• Can be enabled in Little Snitch Settings > DNS Encryption.
• Predefined configurations for the most popular DNS encryption services so you can get started with just a few mouse clicks.

Network Activity Monitoring

• Improved design of the Network Monitor user interface.
• Introducing a revamped traffic chart for clearer visualization and analysis of network activity.
• Versatile grouping options for connections in Network Monitor. Connections can now be grouped not only by process but alternatively also by domain/server or by country. So you can quickly see at a glance all apps to connect to a particular country or to a particular domain.
• All connections related to one app are now grouped under one entry in the connection list, including incoming connections and connections established via helper tools.
• Configurable traffic meter appearance: Choose between two types of traffic activity indicators – either a live meter showing the current activity (like in Little Snitch 5) and a new thumbnail chart showing a history of the last five minutes (like in Little Snitch Mini).
• Improved legibility of connection lines shown in the map.
• Display of named location labels in the map.
• Automatic updates of the Geolocation Database for enhanced accuracy and reliability.
• Improved display of App Extensions in the connection list.
• More powerful search and filter options.

Status Menu

• Revamped status menu, including an animated traffic chart, information about recent network activity and recently denied connections.
• Configurable traffic meter appearance: Like in Network Monitor you can now choose between two types of traffic activity indicators to be shown in the menu bar: Either a live meter showing the current activity and a new thumbnail chart showing a history of the last five minutes.

Creating and managing rules

• A new type of rules allows to show notifications in Notification Center whenever a certain kind of network activity occurs.
• Ability to create rules for “Any macOS Process” and “Any Simulator Process”.
• Local, editable rule groups, allowing you to organize rules by topic and enable or disable multiple related rules at once.
• Attach notes to newly created rules directly from within the connection alert.
• Rules now identify processes based on their cryptographic code signature, irrespective of their location in the file system. This makes rules resistant against moving or renaming apps. The previous, path-based identification is still available as an option.
• Bidirectional rules that match both incoming and outgoing connections from/to certain IP addresses or ranges.
• Improved Homebrew support. Rules for Homebrew executables are now independent of the version number, which is part of the executable path.

Sound Notifications

• Get an acoustic feedback whenever a certain kind of network activity occurs.
• Become aware of such network activity even when you are not actively watching the Network Monitor window or when you don‘t even watch your screen.
• Select from a fun variety of built-in notification sounds.
• Some of the sounds are modulated to also indicate the amount of data that is currently transferred.

Usage statistics for rules and blocklists

• See how often rules or blocklist entries have been used and when they were last used.
• Sort the rule list by “Last Used Date” or by “Usage Count”.
• The new “Unused” filter helps you quickly find rules that haven’t been used for quite a while.

Other new features and improvements

• Customization options to disable specific types of notifications from being shown in Notification Center.
