The hidden network quality tool in macOS Monterey

Usage

It seems that Apple has quietly added a new tool in macOS Monterey for measuring your device’s Internet connectivity quality. You can access this tool via the terminal on your computer. To do so you would simply type networkQuality in the terminal prompt to execute the utility.

Running the networkQuality command will provide the following information once the process has been completed.

  • Upload/download capacity (Tx/Rx bandwidth)
  • Upload/download flows, this is the number of test packets used for the responsiveness tests
  • Upload/download responsiveness measured in Roundtrips Per Minute (RPM), which according to Apple, is the number of sequential round-trips, or transactions, a network can do in one minute under normal working conditions

The capacity is more or less the same measurement that other online tools such as Fast.com, Speedtest, or TestMyNet would be providing to you.
