AirStats1.6

AirStats puts live system readings in the macOS menu bar, giving you a quick view of how the machine is behaving without opening a conventional monitoring window. It offers sixteen metrics, so you can display only the two you watch most or expose the full set.

Clicking its panel reveals per-core load, memory pressure, and top processes, while the monitor also covers GPU, network, disk, battery, and temperature data. Each metric includes a view of the last 24 hours, and you can pin selected modules to the desktop for persistent visibility. Set a threshold for a metric to receive a notification when it crosses that level, then assign individual colors or use a monochrome display.

A desktop widget keeps chosen metrics in view at all times, and both the panel and widget can be opened without mouse input. Apart from the optional public IP lookup, which is disabled by default, the information shown is read directly from the Mac. AirStats runs as a single process without a helper or launch agent, so quitting it leaves none of its components running. It requires no account, trial, or paid tier.

AirStats 1.4 is a freeware System Tools utility distributed under the MIT license. It runs on MacOS with macOS 14 Sonoma or later and supports Apple Silicon arm64 only; its compact build is 8.9 MB.
