A menu bar app to watch and tune Mac performance
MenuBarMonitor is a for checking CPU, GPU, NPU, memory use, temperatures, and fan speed. It lets people arrange those readings and change the look of the icons, graphs, and colors. Unlike apps that only show system stats, it also offers controls such as freeing memory and assigning apps to or .
The goal is to move less important foreground apps to lower-power cores and reduce power use. It says it shows real memory use instead of only “free memory,” which can be misleading. It also points out apps that are quietly using a lot of CPU in the background.
A small floating widget can sit on a second screen for gaming, benchmarks, or constant monitoring.
