Know why your Mac is busy.

A free menu bar monitor for CPU, memory, disk and temperature, built for developers. It names what is using your Mac: the simulator you forgot, the Gradle daemon, the build.

Nabız in the menu bar: CPU 43%, RAM 72%, SSD 168G free, temperature 58°

The Nabız panel: processor, memory, disks, temperatures, open simulators and the busiest processes grouped by owner

Not just how busy. Who.

Activity Monitor lists hundreds of processes with names like amsengagementd. Nabız groups them by what you actually started.

Simulators by name

The 200+ processes inside an iOS simulator count under the device you know, along with the disk image reads that feed it.

Idle simulator alerts

Left one booted after a test run? After 30 quiet minutes you get a notification with a Shut Down button.

Apps, not helpers

Code Helper, WebKit and virtual machine processes are counted under the app that started them.

Developer tools, named

Xcode builds, Gradle and Kotlin daemons, Maestro, and Android emulators with their AVD names.

System services in plain words

mds_stores, WindowServer, kernel_task and friends get a one-line explanation.

Temperature without root

Chip and SSD sensors, read directly. No helper tool, no admin password.
