Notifies you each time an app tries to connect to a remote server
To be more exact, LuLu runs in the background on your Mac and displays an alert as soon as any application tries to make a connection to a remote Internet server. LuLu is a free macOS app designed to complement macOS' firewall by adding automated blocking capabilities for all outgoing Internet connections. Apple's macOS firewall is a handy tool for users who require a high level of security as it blocks unauthorized incoming Internet connections from reaching your Mac.
