ActivityLine

ActivityLine is a lightweight system monitoring tool that condenses the real-time running status of your Mac.

Into a single line in the menu bar. It continuously displays CPU, GPU, memory, network traffic, and active application resource usage, ActivityLine allowing users to quickly determine what tasks their computer is currently handling without needing to open Activity Monitor or complex dashboards. Clicking on the dynamic information in the menu bar ActivityLine allows you to switch between metrics of interest; hovering over them reveals the specific applications and processes causing the load. Automatic mode switches to the most important metrics based on resource fluctuations, providing immediate and intuitive feedback when the browser is consuming excessive memory, an application suddenly increases processor load, or there is a sudden network surge. The software offers a smooth display option to reduce visual jumps caused by data changes and supports network alerts, automatic startup upon login, and right-click menu settings. The entire interaction is concentrated in the menu bar, occupying limited space and offering a short viewing path, making it suitable for developers, designers, content creators, and everyday users who want to monitor their Mac’s performance status at all times. The software supports macOS 13 and above and can be used without registration.
