Little Snitch 4.5 nightly (5454)

This release brings new features and improvements requested by users, after a few months of focussing on compatibility with macOS Catalina. In particular:

Redesigned Research Assistant in Connection Alert

Since our Internet Access Policy initiative (IAP) gains popularity and support by more and more third party developers, the IAP has been made the main focus of the Research Assistant. It provides you with first hand information directly from the app developer.

The information from our Research Assistant online database now comes bundled with Little Snitch to supplement processes which don’t have an IAP of their own. It’s therefore no longer necessary for Little Snitch to connect to the online database to retrieve this information.

Along with connection details and possible warnings regarding code identity checks all this information is now presented in a redesigned interface, in a clear and consistent manner.

Other improvements in the Connection Alert
  • When a code identity check fails, it’s now always possible to “accept the modification” and update the identity check, using the executable’s cryptographic hash if nothing else is suitable.
  • When no server name can be derived and only the IP Address of a remote computer is shown, it’s now possible to create rules for the entire subnet, not just the particular IP Address.

Improvements in Network Monitor

  • Network Monitor now shows accesses to the Berkeley Packet Filter (BPF), and rules for this kind of access can now be managed from within Network Monitor as well.
  • Since BPF access can now be managed in Network Monitor, BPF related connection alerts no longer appear in Silent Mode.
  • All server names ending in .local are now grouped in one single “local” domain.
  • Improved rule creation from within Network Monitor. If a similar but currently disabled rule already exists, it is replaced by the newly created rule.
  • The context menu for a connection now offers an “Until Logout” option when the Shift key is held.
  • Fixed an issue where Network Monitor stopped showing connections.
  • Fixed an issue where macOS would change Spaces when a full screen app is active and Network Monitor is brought to front.
  • Fixed: When there are no rules matching a connection, buttons for rule creation are only shown when the mouse is at the prospective button location. This prospective location was sometimes off by half a button width, making it hard to create an allow-rule. This issue has been fixed.
  • Fixed an issue where geographic labels on the map could be off by half a map width.

Improvements in Little Snitch Configuration

  • Improved editing of a selection of multiple rules.
  • In order to derive code identity information, Little Snitch Configuration must read the executable files of processes. If an executable cannot be read due to file permissions, we now derive code identity information via a privileged component.

General improvements and fixes

  • Improved the selection of suitable sections from the Internet Access Policy of a process.
  • Fixed detection of remote endpoint name for Viscosity VPN.
  • Fixed a crash of Little Snitch when other programs write garbage to the System Configuration. This crash occurred with a Microsoft Active Directory client for macOS.
  • Numerous other bug fixes and improvements.

You probably came here because your Mac showed a message telling you that software from “Objective Development Software GmbH” (Little Snitch) loaded a system extension that will no longer be compatible with a future version of macOS and that you should contact us, the developer, to get more information. Well, here you are.

In order to be able to perform filtering of network traffic, Little Snitch 4 installs a kernel extension (the above mentioned “System Extension”) which is based on Apple’s “Network Kernel Extension” API (NKE).

This API will be deprecated in a future version of macOS and replaced with a new “NetworkExtension” API (NE). Despite their similarity in name, these two APIs work very differently, so the underpinnings of Little Snitch do require a substantial rework.

Will there be an updated version of Little Snitch that is compatible?

Yes. We are going to release an update of Little Snitch that will utilize the compatible replacement APIs.

When will Little Snitch 4 become incompatible?

We expect the deprecation to become effective with the next major release of macOS. There’s no official release date from Apple, but based on the release schedule of recent years it will not be before this fall. Little Snitch 4 will then not be loaded by the operating system, but there will still be an option to allow the loading. [1]

What happens in the unlikely case that no updated version of Little Snitch is available at that time?

We do our best to have an updated version available right in time. But if you’re still concerned – keep in mind that there will be an option in macOS to allow running Little Snitch 4.

If I buy Little Snitch 4 now, will I get the update for free?

Yes. All licenses sold now include a free upgrade to Little Snitch 5. In addition, customers who purchased Little Snitch 4 within a one-year period prior to the final release of Little Snitch 5 (about this fall) will also get a free upgrade. And if you purchased Little Snitch 4 before that period, we will offer you an upgrade at a reduced price.

When will Little Snitch be updated to the new APIs?

The replacement APIs that are currently available (NetworkExtension framework on macOS 10.15.4) are not yet completely sufficient to implement the full functionality of Little Snitch. Bitcoin miner little snitch. But we are working closely with Apple to fill the remaining gaps and we expect that a beta of the next major macOS version (most likely available at the next WWDC) or even an upcoming version of 10.15 will provide what is missing. As soon as the APIs allow us, we will complete the transition of Little Snitch to the new NetworkExtension API. It’s our goal to provide a public beta in June 2020 and a stable version in October.
