I tried and liked LittleSnitch 4, the new approval process seems like a trivial change, but it's *so* much smoother.
But having to retrain LS4 after every reboot because it forgets the prior rules? A bug I'm not willing to work around.
I reinstalled LS 3.7.4 yesterday, spent a good eight hours using my machine and retraining my firewall.
Only to start at ground zero again this morning.
Dunno what causes this, cringing at the thought of a reinstall from scratch to clear whatever LS4 issue causes this.
