Native macOS developer tools

Reproduce real QA conditions.

MacStressQA gives developers and testers simple, controllable CPU, GPU, and memory loads for repeatable testing on Apple Silicon Macs.

Apple Silicon / macOS 15+ No account required CPU / GPU / memory

01 / 01

Controlled. Repeatable.

Apple Silicon / ReadyIdle

QA load test

Choose a load to begin.

A / 01

Load the Mac on purpose. Learn what happens next.

01 / Featured app

A clear way to create a known load.

MacStressQA stays focused: choose a workload, set a target, and see how your Mac behaves under a condition you can reproduce.

Coming soon to the Mac App Store

Repeatable load testing for your Mac.

Set CPU, GPU, and memory load independently, then start and stop each workload as you test.

Get launch updates

Choose a target for CPU, GPU, or memory instead of relying on a black-box benchmark.

Start and stop each workload independently while you reproduce a QA condition.

Built with SwiftUI for Apple Silicon. No account, analytics, or telemetry.

02 / The approach

Small tools should make the test easier to set up, easier to understand, and easier to repeat.

Choose the workload and the target instead of relying on a black-box benchmark.

Create a known test state, then use it again while you debug or compare changes.

Native SwiftUI, public Apple APIs, and no account or telemetry in the way.
