This is a hotfix for a bug in macOS Big Sur Beta 5! Please install this version before upgrading to Beta 5! Otherwise you won’t be able to boot your computer!
This version does not install an Endpoint Security System Extension because Big Sur Beta 5 suffers a kernel panic immediately after booting this System Extension is installed. During upgrade, an existing Endpoint Security System Extension is removed. Currently, the only function of the Endpoint Security System Extension is to detect access to Berkeley Packet Filter devices. This version can therefore not warn when a process tries to access the Berkeley Packet Filter.
The good news is that Big Sur Beta 5 fixes an other kernel panic which occurred on some computers when Little Snitch’s Network Extension was installed.

This Technology Preview of Little Snitch is not yet feature complete. There are several known limitations you should be aware of before you install:
During the installation you will be asked to enable system extensions in System Preferences > Security & Privacy. After clicking on “Open Security Preferences”, the same dialog will appear once again. This is a bug in macOS Big Sur.
After clicking on “Allow…” in System Preferences > Security & Privacy, you will see a confirmation dialog containing two entries labeled “Placeholder Developer”. These incorrect labels are a bug in macOS Big Sur. The checkboxes for both of these entries must be checked.
