What macOS shows on its own
Activity Monitor’s Network tab shows data received and sent per second at the bottom of its window.
How Multimeter shows it
- Bytes in or out per second across your Wi-Fi and Ethernet connections, sampled every 3 seconds on power and about every 6 on battery.
- The range follows your recent peak, so the graph stays useful on both a slow café connection and gigabit at home. Set a fixed range if you prefer.
- One meter per direction, labelled DOWN or UP by default.
Set it up
- Choose Add Meter… and pick Network.
- In Customize, choose Download or Upload.
- Pick Sparkline to see bursts over time, or LCD Readout for the number.

Limits
This is what your Mac is sending and receiving right now, not a speed test of your connection’s maximum.
Questions
Is this a speed test?
No. It shows current traffic. A speed test measures the most your connection can do; this shows what’s flowing at the moment.
