Has totally replaced Little Snitch for me recently after being increasingly annoyed by it over a decade of using it. This type of software requires lots of trust in the developer and objective-see has earned that trust with the many great projects they provide.
I miss how LS was much more granular in allowing specific connections. In Lulu when I approve an app, it's all app's connections by default, unless I am creative with a regex to capture proper connections. That's a major downside compared to LS. Or am I missing something?
