開発者より: Mole helps you review leftovers after uninstalls, clear caches, and see what's using disk space before anything is deleted. The command-line tool is free and open source.
開発者より: WiAware lives in your Mac’s menu bar and tells you, in plain words, whether your connection is good enough for a call. The icon is the answer: a full wave means calls are fine, a broken wave means they may stutter, and a dot means they won’t work.
Mac向けのFrom its maker: An Activity Monitor alternative: every process grouped under its app, with live charts, 30 days of history, alerts and a menu bar monitor. $5 at launch.
開発者より: Netfox turns raw network data into plain English on your Mac: decode every device, see what it exposes, and catch services left open. No cloud, no account.
Look for low overhead of its own, which sensors it reads on Apple silicon, and whether it can live in the menu bar.

What is the best system monitor for Mac?
There is no single best one for everyone. MacPip lists 5: Mole, WiAware, HeartbeatMac, Netfox, Taskglass. If you want it free, look at Netfox. If you would rather pay once than subscribe, look at Mole. If you want it to run natively on Apple silicon, look at HeartbeatMac. If you need it to work offline, as its maker says it does, look at Taskglass. If you want open source code, look at Mole.
