Sixteen analyzers find what’s actually slowing your Mac down. Caches, startup items, memory pressure, disk health. Then fix it — reversibly — in one click.

Why Nuro
Sixteen analyzers run in parallel — battery, memory, disk SMART, startup items, thermal pressure — and surface what’s actually wrong in seconds.
Cache cleaning sends files to the Trash, not /dev/null. Startup-item changes are transactional with auto-rollback if any step fails.
No analytics SDKs, no crash reporters, no license servers, no sign-ins. The app talks to the network in three places — the auto-updater, and two opt-in network tools (Speed Test, DNS Benchmark) you trigger yourself with a one-time consent. Nothing is sent to us, ever.
One-Click Optimize
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.
Snapshot
Capture disk free, memory pressure, swap, top processes.
Clean caches
Reversible — files move to the Trash, not deletion.
Disable startup items
Transactional batch — rolls back automatically on any failure.
Purge memory
Free inactive memory and reduce pressure on swap.
Snapshot & compare
Inline before/after — proof, not promises.

Privacy by default
Nuro Optimizer collects nothing. No analytics, no crash reports, no license checks, no accounts, no sign-ins. The app talks to the network in exactly three places: an unauthenticated update check against a public, EdDSA-signed feed (you can disable it), and two opt-in Network tools — Speed Test and DNS Benchmark — that you trigger yourself, each gated behind a one-time consent banner. Nothing about you is ever sent to us. Everything else stays on your Mac.
