A free macOS optimizer from Sentium Nuro Labs. Sixteen analyzers find what's actually slowing your Mac down — caches, startup items, memory pressure, disk health — then fix it, reversibly, in one click.

This repository hosts:
- The marketing site (

The Swift source for the app itself lives in a separate private working tree.
Nuro Optimizer needs Full Disk Access, the ability to invoke launchctl, read SMART data, manage system caches, and control startup items. All of these are blocked by the App Sandbox required for Mac App Store apps. So we ship via Apple's notarized Developer ID program — same path as CleanMyMac, OnyX, BetterDisplay, and most macOS utilities of substance.
Every release on this page is:
- Built with

arm64+x86_64) - Code-signed with
Developer ID Application: DONTE' MAURICE WONG (B9HPU9TVCR) - Hardened Runtime enabled

- No telemetry. No analytics SDKs, no event tracking, no usage reporting.
- No accounts. No sign-in, no email gate, no license keys.
- No crash reporting. No third-party crash collectors (Sentry, Crashlytics, Bugsnag, etc.).
- No license server. The app is free; there is nothing to check.
- One outbound network call, and it's optional. The app uses Sparkle to deliver updates. On launch and on a schedule, Sparkle fetches
https://optimizer.getsentium.com/appcast.xml— a public, unauthenticated XML file that lists available versions. The request sends no information about you or your machine beyond the standardUser-AgentSparkle uses. Updates are EdDSA-signed; Sparkle refuses to install anything that doesn't verify against the bundled public key. You can disable automatic checks entirely in Nuro Optimizer › Settings › Updates.
Verifiable with lsof -i -p $(pgrep "Nuro Optimizer") or Little Snitch. The full privacy policy lives at optimizer.getsentium.com/privacy.html.
