Network Utility is back
Apple removed Network Utility from macOS. NetUtil brings it back with a modern interface. Ping, traceroute, DNS lookup, port scan, and more.
Requires macOS 14 Sonoma or later
Remember Network Utility?
For over 20 years, Network Utility was the go-to app for diagnosing network issues on Mac. Then Apple quietly removed it in Big Sur. No announcement. No replacement. Just gone.
NetUtil fills that gap.
Seven essential tools
Everything Network Utility had, rebuilt for modern macOS.
Ping
Test connectivity to any host. See response times in real-time with clear statistics.
Traceroute
Map the path to any destination. Identify where slowdowns or failures occur.
DNS Lookup
Query DNS records. Check A, AAAA, MX, CNAME, TXT, and more.
Netstat
View active network connections. See what's connected and what's listening.
Whois
Look up domain registration info. Find ownership and contact details.
