Eleven care surfaces
Everything your Mac needs, in one app.
Fast Scan covers nine of them in a single pass. Monitor and Shredder are always-on surfaces outside the scan. Surfaces marked Direct need the Direct edition, because the App Sandbox cannot do writes.
Guard
Signature malware scan plus a user-space realtime file-event watch.
- On-demand signature scan against a local database
- Realtime FSEvents watch alerts on new matches — it never kernel-blocks
- Privacy traces and sensitive permission review
Tune
Maintenance tasks, login items, and background services you control.
- Maintenance tasks and Time Machine snapshot thinning
- Login items and background services review
- Every task runs only after your confirmation
Apps
An inventory with on-demand sizes and an uninstaller that finds leftovers.
- Sizes enriched on demand, so the list opens instantly
- Uninstall removes the bundle plus support files and receipts
- Leftover sweep for apps you already deleted
Files
Large files, duplicates, similar images, and stale downloads.
- Similar-image clusters with a side-by-side visual compare
- Exact duplicates with smart keep suggestions
- Large, old, and download clutter flagged for explicit review
Storage Map
A graphical, zoomable map of what actually occupies the volume.
- Treemap and sunburst views with drill-down
- Synchronized list for keyboard and VoiceOver users
- Selection feeds the review flow — the graphic deletes nothing
Cloud
Dropbox, Google Drive, and OneDrive cleanup over OAuth PKCE.
- OAuth PKCE sign-in over a loopback redirect — no shared secrets
- Removals land in the provider trash, so originals stay recoverable
- iCloud Drive scanned locally from its on-disk sync folder
Local AI
Model weights, editor and CLI caches, and local vector stores.
- Hugging Face, Ollama, LM Studio, and ComfyUI weights
- Editor and CLI caches (Cursor, Claude Code, Copilot, and more)
- Prompt history is high-risk and never auto-cleaned
Silicon Health
Apple-silicon swap-write risk, battery cycle health, and S.M.A.R.T. status.
- Swap-write rate and 24h projection from real samples
- Battery cycle count against the rated design life
- Disk S.M.A.R.T. status as reported — never guessed
Monitor
Live CPU, memory, swap, network, battery, and disk graphs. Read-only.
- Sampling every 2 seconds with an 8-minute rolling window
- Thermal state, battery, and free-storage vitals
- Strictly observational — nothing on your Mac is changed
Shredder
Confirmed multi-pass secure delete for files that must not come back.
- 1 or 3 overwrite passes before truncate and unlink
- Per-file confirmation — nothing runs without an explicit confirm
- Honest about limits: snapshots and SSD wear-leveling
Everyday surfaces
Present where you already are.
FastSweep lives in the menu bar, on your desktop, and on a schedule — not just in a window you have to remember to open.
Menu-bar popover
Status at a glance with per-metric sparklines, quick actions, and the next scheduled maintenance run.
Desktop widget
A read-only status snapshot on your desktop with deep links straight into the matching screen.
Scheduled maintenance
Daily, weekly, or monthly automatic runs. The menu bar always shows when the next run is due.
App updater
One-click installs fetched from cryptographically signed manifests, verified before they run.
Screen Cleaning Mode
An input-dimming overlay so you can wipe the display safely. Three enforced escape routes, 120s hard cap.
Activity log
A local record of every action with item, path, size, behavior, and result. Yours, on your disk.
The popover samples live vitals and keeps a per-metric sparkline history in memory. Scheduled maintenance shows its next run in the menu bar; in the Mac App Store edition the schedule reminds you instead of running writes automatically.
Why FastSweep
Powerful cleanup you can actually trust.
Most cleaners are a black box. FastSweep shows its work: clear reasons, sizes, and a full audit log for every action — so you stay in control.
Read the safety modelOne Fast Scan, nine surfaces
A single pass scans Clean, Guard, Tune, Apps, Files, Storage Map, Cloud, Local AI, and Silicon Health — then computes a 0–100 health score with plain-language reasons.
Every item is reviewable
Nothing is deleted until you approve it. Each finding shows its reason, size, and proposed behavior, and safe-by-default items still wait for your review.
Two honest editions
The sandboxed Mac App Store edition is read-only care: scanning, monitoring, and silicon health. The Direct edition adds every write-capable tool. We say which is which.
On-device by design
Scans run locally on your Mac. No account is required to scan and review, and personal data such as prompt history is classified high-risk and never auto-cleaned.
Three steps
Three steps, zero surprises.
- 01
Run Fast Scan
One click scans the care surfaces your edition exposes and computes a health score in seconds. Pause or cancel anytime; partial results stay available.
- 02
Review every finding
Each item lists its reason, size, and proposed action. Similar images open a side-by-side compare so you keep the right one.
- 03
Approve, then act
Only what you confirm runs. Removals go to Trash where possible, and every action is written to a local log you can reopen.
Security & privacy
Safety isn't a setting. It's the design.
FastSweep is built so the dangerous default is impossible: review before removal, Trash over permanent delete, a local log of every action, and no kernel extensions anywhere.
Explore the safety modelOn-device by default
Scans run locally. Scan and review without an account — nothing leaves your Mac.
Review before anything changes
Every finding shows its reason, size, and proposed behavior. Nothing runs without your approval.
Realtime watch that only alerts
The malware monitor is a user-space FSEvents file-event watch. It flags matches; it never kernel-blocks or auto-deletes.
Two editions, stated plainly
The sandboxed App Store edition is read-only. Write-capable tools ship only in the Direct edition, and we label which is which.
Questions
Frequently asked
Is FastSweep safe to use?
Yes. FastSweep is review-first: every finding shows its reason, size, and proposed behavior, and nothing is removed until you approve it. Where possible removals go to the Trash rather than being permanently deleted, and every action is written to a local log so you can see exactly what happened.
What is the difference between the two editions?
The Mac App Store edition runs inside the App Sandbox, so it is read-only care: the Smart Care health scan over read-only system health, the live Monitor, Silicon Health, the menu-bar popover, and the desktop widget. The Direct edition lifts the sandbox and adds every write-capable tool — cleanup, the uninstaller, Guard scanning and its realtime watch, the Shredder, cloud cleanup, the signed updater, and Screen Cleaning Mode. Both editions are the same native app; the edition is decided at build time.
Does the realtime malware monitor block files?
No, and we do not claim that it does. The realtime watch is a user-space FSEvents file-event monitor: it watches file events, matches them against the local signature database, and raises an alert with a proposed quarantine action. It takes no autonomous filesystem action — nothing is moved, quarantined, or deleted until you confirm through the normal review flow. FastSweep has no kernel extension and no kernel-level blocking.
Does FastSweep send my data anywhere?
Scanning, analysis, and cleanup decisions run on your Mac, and no account is required to scan and review. Cloud cleanup connects to your provider with OAuth PKCE over a loopback redirect so tokens never pass through a third party, and provider removals land in the provider trash so originals stay recoverable.
Will it work on my Mac?
FastSweep runs on macOS 11 Big Sur and later as a universal binary for Apple Silicon and Intel. Silicon Health adds Apple-Silicon-specific signals: swap-write rate and projection, battery cycle count against the rated design life, and the disk S.M.A.R.T. status exactly as macOS reports it.
Does FastSweep free RAM, purge memory, or benchmark my disk?
No. Those claims are marketing fiction on modern macOS. FastSweep shows you live memory, swap, and disk signals in the Monitor and explains swap-write pressure in Silicon Health, but it never purges memory or runs disk benchmarks.
Can I uninstall apps completely?
Yes, in the Direct edition. The Apps surface removes the app bundle plus related support files, containers, receipts, launch agents, caches, and preferences — and its leftover sweep finds residue from apps you already deleted. App sizes are enriched on demand so the inventory opens instantly.
Does FastSweep require a subscription or license key?
The Mac App Store edition is free with no account, subscription, or external purchase. The Direct edition is a free download: scan and review work without an account, and write-capable tools unlock with a trial or a plan managed through the in-app account.
Give your system a fresh start.
Read-only care is free on the Mac App Store. The Direct edition adds the full write-capable toolset — cleanup, shredder, cloud cleanup, and signed updates.
