Net-DNS-Monitor support

Help and contact for Net-DNS-Monitor, the macOS menu bar app that watches your network and DNS connectivity and tells you what is actually wrong when it breaks.

Contact

Email [email protected]. Say which version of macOS you are on and which version of the app (the About panel shows it), and attach the incident report if the question is about one; the app's menu hasOpen last report. Reports stay on your Mac until you choose to send one.

What the app does

Net-DNS-Monitor sits in the menu bar and checks, every few seconds, whether your Mac can reach the internet and resolve names. When a check fails it separates the three things that look identical from a browser: your Mac's own link, the local network, and DNS. It runs an offline troubleshooting ladder, records what each step found, and writes an incident report you can hand to whoever runs your network.

What the Mac App Store edition cannot do

Every Mac App Store app runs inside the App Sandbox and may not ask for administrator rights. The store edition therefore leaves out the features that need either, and says so in its reports rather than failing in a way that looks like a network fault:

• switching your network service order to a backup connection;
• flushing the DNS cache or renewing a DHCP lease;
• reading the macOS unified log for evidence;
• the built-in router, the shell console, and starting at login on its own.

To start the app at login, add it in System Settings → General → Login Items. Every other feature, including the diagnosis, the reports, the graphs and the optional alerts, works the same as in the full edition.

First launch

macOS asks whether the app may find devices on your local network. Allowing it lets the app check whether your router answers and compare notes with other Macs running the app nearby. If you decline, those checks report failures; you can change the answer later in System Settings → Privacy & Security → Local Network.

Claude diagnosis

The optional diagnosis by Claude uses your own Anthropic API key, entered underCredentials in the app menu and kept in your Keychain. Nothing is sent to Anthropic until you choose Allow Claude diagnosis… and confirm the dialog that lists exactly what an incident report would contain.Withdraw Claude permission reverses it.

Where your data lives

Settings, incident reports and the connection history stay in the app's own container on your Mac. The publisher receives none of it. Theprivacy policy lists everything that can leave your Mac, when, and how to turn each case off.
