Know What Your Mac Is Doing — Without Opening Activity Monitor

Your Mac is usually quiet. A fan starts spinning, an app feels slow, a download behaves strangely, or disk space suddenly gets tight. Then you want to know what is going on without opening a large monitoring window. That is where a menu bar meter makes sense. The menu bar is always visible. It is the right place for small system signals: CPU load, memory usage, disk space, and network activity. Not a complicated graph wall. Just the numbers you want to see while you work. https://medium.com/@chris.ahrweiler/know-what-your-mac-is-doing-without-opening-activity-monitor-938007afc7d6
