Little Snitch 6.3

What's new in this version:

New Features and Improvements:
General:
- Added support for macOS 26 Tahoe
- Added Internet Access Policy support for Safari web apps added to the Dock
- Improved loading of blocklist to treat semicolon-prefixed text as comments, preventing false positives
- Improved display of app bundle paths in the inspector of Network Monitor and in the rules window
- Connections made by an app on behalf of Password AutoFill (typically to fetch website icons) are now attributed to the Password AutoFill helper process instead of the app itself
- Connections from XPC helper processes used by app extensions are now attributed to their corresponding extension
- Improved parent process detection for apps running a copy of themselves from a temporary folder

Configuration:
- Added quick filters to the search field for showing only active or inactive rules in the rule list
- Added action menus for some fields in the rule inspector (for example to change the process owner setting of a rule)
- Improved the header section of the rule list to better describe the current contents of the list (the number of rules currently shown, the kind of filter currently applied, etc.)

Status Menu and Connection Alert:
- Improved appearance of headings in the status menu
- Selecting an app from the “Recent Network Activity” list in the status menu now focusses on connections of only that app in Network Monitor
- When a process declares a custom process name at runtime that differs from the actual name on disk, that custom name is now also shown in the details section of the connection alert

Network Monitor:
- Improved responsiveness when allowing or denying connections from the connection list
- Reduced energy consumption by disabling animations while the window is not visible (either hidden or covered by other windows)
- Sorting the connection list by name now shows app groups (like “macOS”) always at the top
- Added a “Focus on” context menu option in Network Monitor to focus the list on connections for a particular app, process, domain, or country
- The inspector now shows a warning triangle next to the Code ID of a process if that ID no longer matches the ID of the corresponding executable on disk. This can happen typically when the developer has changed the bundle identifier of their app with an update

Fixed:
General:
- Fixed incorrect parsing of small IPv6 address blocks in blocklists (e.g. /128 was incorrectly imported as /12)

Network Monitor:
- Showing correct icons and localized names for iOS/iPadOS apps running natively on macOS
- Fixed incorrect geographic attribution of Private Relay connections to Åland

Configuration:
- Display the Welcome window and setup questions correctly after reinstalling, even if a previous installation was incomplete
- Fixed a crash caused by rule usage counts exceeding 4 billion
- Fixed the “Networks” sidebar not updating after changing profile details
- Fixed the “Automatic Profile Switching” pane not updating after changing profile details
- Fixed search scope changes not applying while focusing on a set of rules
- Fixed the highlight color of the Notes field in the inspector updating incorrectly when switching system appearance between dark and light
