Why it matters

Find what’s using your Mac’s resources

MōStats puts live metrics, grouped processes, and process details in one compact utility.

Overview Keep live stats nearby

Open a compact window from the menu bar for CPU, memory, network, disk, uptime, and temperature.

Processes See usage by app

Apps stay grouped with their helper processes, so resource ownership is easier to read.

Details Inspect a process

Drill into any process to see what it is, where it runs, and quit it when needed.

What it does for you

Small enough to keep open

Quick checks, no context switch

Pin MōStats while you work and see what changed without opening Activity Monitor.

Works right away

No accounts, dashboards, or projects. Just live system stats when you need them.

Local system data only

Process and metric data stays on your Mac and is used only for display, search, and filtering.

How it works

Made for quick checks

Check live metrics

Open MōStats from the menu bar for a live read on CPU, memory, network, and more.

Find the app

Switch to Processes and filter instantly by name, PID, path, or arguments.

Check the process

Select a point on an app’s graph to see how much each child process was using at that moment.

Inside the process view

Details you can check quickly

Process identity

See the process name, PID, parent PID, owner, bundle ID, start time, thread count, and CPU time.

Command-line arguments

Inspect launch arguments that explain helper modes, profiles, or background services.

Executable path

Check where a process runs from and reveal the executable in Finder.

Careful process actions

Send Quit or confirm Force Quit when a process needs intervention.

FAQ

Honest answers about how it works

Is MōStats a replacement for Activity Monitor?

For quick checks, often. It focuses on a compact live overview and a searchable process explorer. Activity Monitor still has deeper Apple diagnostics that MōStats does not try to copy.

Which metrics can I see?

CPU, memory, network throughput, disk usage, uptime, and CPU temperature when macOS exposes a trustworthy sensor reading.

What can I search for?

Process name, PID, executable path, bundle ID, and command-line arguments.

Can I see which child process caused a spike?

Yes. Open an app group and inspect the selected graph tick to see the CPU and memory split across that app’s child processes.

Can it quit processes?

Yes. It can reveal an executable in Finder, send Quit, and confirm Force Quit. It refuses MōStats itself and critical system processes.

Does it show when an app is frozen?

Yes. MōStats marks an app Not Responding when macOS reports it unresponsive.

Why are some values unavailable?

macOS may deny a process field or avoid exposing a stable source, especially for CPU temperature on Apple Silicon. MōStats marks the value unavailable instead of guessing.

Is it free?

Yes. MōStats is free and open source on GitHub, with an MIT license.
