Test Your Internet Connection with macOS networkQuality

01Command

$ networkQuality -v

02What it does

networkQuality contacts Apple's measurement servers and reports download speed, upload speed, and Responsiveness (RPM) — a measure of how well the connection handles multiple simultaneous streams, which matters far more than raw Mbps for video calls. The -v flag adds details like the test servers and interface used. Unlike a typical speed test it deliberately saturates the link in both directions at once, which is why video calls drop on some connections that look fast in other tests.
