A few useful answers
MacShield supports Apple Silicon and Intel Macs running macOS 15 or later. Network monitoring requires approval of its system extension and content filter in System Settings.
No. MacShield monitors connections by default. Only enabled Block List rules that you add manually can block traffic. You can create rules for apps, domains or IP addresses, including wildcard domains and explicit app exceptions.
Traffic history and rules stay on your Mac. MacShield does not store packet contents. Connection maps use a bundled IP-location database; Apple Maps may request background map tiles.
Locations are approximate estimates from the destination IP address, not the physical location of a person or device. Local-network connections, observed Private Relay hostnames and destinations without a known location are shown separately.
Some encrypted connections hide their destination hostname. MacShield shows names when they can be observed and uses IP addresses where a name is unavailable. You can use app or IP rules for those connections.
Yes, when Allow running in background is enabled. You can keep live speeds and a traffic graph in the menu bar, hide the Dock icon and start MacShield automatically at login.
