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.

Click the “X” icon that appears on the left upper corner of Little Snitch Configuration, and click on the Delete button in the confirmation dialog.

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.
If you've already installed it and want to change drives, you must uninstall Visual Studio and then reinstall it. Dev c++ visual studio farkı.
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. 
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. 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.
