Netsweep finds no devices, or only my Mac

Netsweep needs Local Network access. Open System Settings › Privacy & Security › Local Network and turn Netsweep on, then scan again.

Devices show up without ping times or names

A VPN or firewall on your Mac can block traffic to local devices. Allow local network access in your VPN app, or disconnect it while scanning. Some devices also simply do not answer ping or announce a name.

Why do some devices say “Private address” as the manufacturer?

Phones, tablets and many laptops use a randomised MAC address on Wi-Fi, so the real manufacturer cannot be looked up.

How do I scan a different network or range?

Pick an interface in the toolbar, or enter a custom range such as 192.168.1.1–192.168.1.100 or 10.0.0.0/24.

How do I change which ports are scanned?

Open Settings › Port Scan and choose common services, ports 1–1024, all ports, or a custom list.

How does iCloud sync work?

Turn it on in Settings › General on each Mac signed in to the same Apple Account. Custom names, comments and links are merged, with the most recent edit winning.

Is it OK to scan any network?

Only scan networks you own or have permission to scan.
