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

It’s looks like I have to pay 25€ for a new compatible version.It's not that Bluetooth stops scanning, but it's not scanning as aggressively. So after a few minutes, there will be very high jitter when Bluetooth scans the environment, but it would affect only a single packet. It's easily reduced its chattiness by 99%. I don't have any empirical data to support the claim that Little Snitch has anything to do with it (and I am too lazy to dig further into it), but the reduction in jitter is massively noticeable since Little Snitch. Which means I can now run Catalina with Bluetooth enabled and not have any wi-fi problems. Just FYI, for the archives :-). Mark.Cheers, Darwin-.
