Tahoe Won’t Unload Network Extensions
Back in our pilot Deletion Impossible, you learned about a bug in macOS 15.3 where dragging an app to the Trash did not reliably uninstall its system extension. Despite macOS promising to “remove the associated system extension,” the extension often stayed behind.
With macOS 26 Tahoe, this problem has reappeared. Once again, moving an app to the Trash does not always remove its embedded system extension, even though the system dialog claims it will. The result: a system extension still running on your Mac long after you thought you had uninstalled the app.

You can confirm whether an extension is still present by opening a Terminal window and running the following command:
systemextensionsctl list
Little Snitch 3.3 has some improvements, though:
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.
