How it works

No wizards. No drama. Three steps.

No "we found 9,847 problems!" theatrics. Just transparent scanning and clean, reversible actions.

STEP 01

Launch & scan

Open StayCleanMac and run a Quick Scan. Every category scans in parallel on Apple Silicon — dashboard stays responsive the whole time.

STEP 02

Review findings

Every category shows exact file paths, sizes, and contextual notes. Smart Clean pre-selects only items macOS will rebuild on demand.

Clean with Undo

Everything goes to Trash first — nothing is permanently deleted. Press ⌘Z or tap Undo in the toast to restore instantly.

Six ways to clean

Six tools.
No bundleware.

Six focused tools instead of fifty. Each one does one job, transparently, and reversibly.

Smart Clean, one click

Automatically identifies safely-regenerable caches and moves them to Trash. macOS rebuilds them on demand — you just get the space back.

Privacy & safety

Your Mac.
Your data. Nobody else's.

Every scan runs on your Mac. Nothing uploads, nothing phones home. If your network disappears mid-scan, StayCleanMac doesn't notice or care.

No cloud uploads, no telemetry

Zero outbound connections during scans. No analytics, crash reports, or "anonymized usage data."

Trash-first, always

Every action moves files to Trash — never permanent delete. You stay in control of the final empty.

Undo everything with ⌘Z

A toast appears after every operation. Tap Undo or press ⌘Z within 10 seconds to instantly restore.

Signed, notarized, hardened

Developer ID signing, Apple notarization, hardened runtime. Updates delivered securely via Sparkle with EdDSA signatures.

Questions, answered

Frequently asked.

Is StayCleanMac really free?
Yes. StayCleanMac is free, with no ads, trials, or premium tiers. It's distributed on GitHub Releases as a signed and notarized DMG. If you want to support development, sponsor the project — but there's no paywall gating any feature.
Why does it need Full Disk Access?
To scan protected Library folders like ~/Library/Caches and ~/Library/Preferences, plus system paths like /Library/LaunchDaemons. macOS requires explicit permission for these. You grant it once at first launch through System Settings — StayCleanMac never transmits what it finds.
What if I accidentally delete something important?
Every operation moves files to the Trash first, and a toast appears with an Undo button. Press ⌘Z or tap Undo within 10 seconds to instantly restore. Beyond that, items live in your Trash until you empty it. The only exceptions are system-level startup items and permission resets — those are noted explicitly and cannot be undone.
How is this different from CleanMyMac or similar apps?
StayCleanMac is focused and transparent. Six clearly-scoped tools, no "performance score" theater, no subscription, no cloud sync, no sign-in. It's written in SwiftUI as a native Apple Silicon app, weighs 4.6 MB, and shows you exactly what it will do before acting.
Does it work on Intel Macs?
Yes — StayCleanMac ships as a universal binary for both Apple Silicon and Intel. It requires macOS 14 (Sonoma) or later.
How do updates work?
StayCleanMac uses the Sparkle framework with EdDSA-signed releases. It checks for updates every 24 hours in the background. Downloads come from GitHub Releases — you can review every version before it ships.
