You can supposedly still use 4.5 4.6 on Big Sur if you do the following but I have not tested it on Little Snotch, works fine for personal software and others ...

codesign -dvvv littlesnitch.package name
Save the team identifier
Boot into recovery mode
Open terminal and type the following...
spctl kext-consent add <team identifier>
Reboot into normal user mode and install version 4

The fact that there's a highway to Hell but only a stairway to Heaven says a lot about anticipated traffic volume.

Which means I can now run Catalina with Bluetooth enabled and not have any wi-fi problems.
