Why Nuro

Built on three principles.

One tap to diagnose.

Sixteen analyzers run in parallel — battery, memory, disk SMART, startup items, thermal pressure — and surface what’s actually wrong in seconds.

Every fix, reversible.

Cache cleaning sends files to the Trash, not /dev/null. Startup-item changes are transactional with auto-rollback if any step fails.

100% offline.

Zero network calls. No telemetry, no analytics, no crash reporting to third parties. What happens on your Mac stays on your Mac.

One-Click Optimize

Five steps. One button.

Snapshot your system. Clean caches. Disable startup items. Purge memory. Snapshot again. See the before-and-after side by side, no guesswork about what changed.

Skip any step. Undo the whole thing. Or run it on a schedule. The optimizer is built for the way you actually use a Mac.
