Know what changes. Know why.

Systune is a Mac cleaner, disk analyzer, security auditor and settings tool in development. It is built around a reviewable plan: inspect the findings, choose what matters and confirm the change.

Before a change

Inspect file paths, sizes and ages
Read the category’s risk and explanation
Keep careful and dangerous categories off until needed
Review the actual removal plan

After a change

Read the history of the cleanup run
Review completed and interrupted work
Restore saved preference values from settings snapshots
Keep backups for files that cannot be recovered

Planned at US$39 once for three household Macs, with two years of updates. Compare Systune with other Mac tools, including where they are stronger.

Clean

See it before you lose it.

103 categories, each with a risk level and a plain description of what it holds. Scan, review, then read the test strip — the sheet that states exactly what the commit will do, path by path, before it does anything.

Caches of running apps are skipped, not silently deleted
A protected-path policy refuses your keychain whatever a category claims
Review Trash or permanent deletion before confirming
Careful and dangerous categories are off by default

18.3 GB found on the developer’s own Mac, in build folders and toolchains alone.

Clean

Analyze

Find out what is actually using the disk.

Four views of the same folder, switched with one control: a list, a squarified treemap, concentric rings, and a breakdown by file kind. Folders are measured one at a time, so you can start browsing while the rest finish.

Largest files, files nobody has opened in months, and duplicates
Hard links counted once, so the totals are the truth
Stop any walk early — the figures then say “so far”

Disk

Audit

92 checks, one honest score.

FileVault, SIP, the firewall, every sharing service, background items that run as root from a folder you can write, plug-ins that load into other apps, keys allowed to log in over SSH. Many findings come with a one-click fix.

A check that cannot be read reports unknown — never a pass
Informational findings carry no weight in the score
Run it deeper with administrator rights, or not at all

Audit

Tune & Maintain

300 settings. Undo on all of them.

The defaults Apple buried, in one place and in plain words — Finder, the Dock, the keyboard, the trackpad, power, security, Safari. Four profiles to apply a whole posture at once. Changes save prior values in a snapshot, ready to restore when needed.

67 maintenance tasks: rebuilds, service restarts, read-only reports
Tasks whose tool a newer macOS removed say so instead of failing
Settings macOS keeps protected say they need Full Disk Access

Tune

The Maintenance page: tasks grouped by kind, each with a risk badge and a Run button.

The promise

Nothing is removed that a scan did not list first.

That is the rule the whole engine is built around. Everything below follows from it.

Plan, then confirm

Interactive by default. The test strip states every path, count and byte before the commit, and waits.

Know what can be restored

User files can go to Trash; regenerable caches may be deleted in place. Settings changes save prior values in snapshots.

Protected paths

Your keychain, iCloud Drive, Photos, Mail and Messages data are refused whatever a category asks for.

Honest about doubt

A check that cannot be read says unknown. A folder it could not open says so. No figure is invented.

A written record

Every run — cleans, settings, maintenance, startup edits — is recorded on disk and readable later.

Reviewed, repeatedly

Five rounds of independent security, correctness and performance review, with the findings published.

Every round is written up — what was found, what changed, and what was left alone on purpose. Ask for the review log →

One engine, four ways in

A real app. And a real command line.

The same Rust engine drives all four. Nothing is a wrapper around a shell script, and the terminal is not an afterthought — it does everything the app does.

macOS app

The full product, native and notarized, with the visual disk views and the test strip.

Command line

Every command takes --json. Scriptable, pipeable, and safe to run from cron.

Full-screen TUI

A dashboard in the terminal for people who live there. One keystroke to each surface.

iPhone companion

Pair over your own network to check on a Mac, and clean the phone’s photo library.

Questions about Systune

What is Systune?

Systune is a Mac cleaner, disk analyzer, security and privacy auditor, and macOS settings tool. It combines 103 cleanup categories, 92 audit checks, 300 settings and 67 maintenance tasks with a Mac app, CLI and full-screen terminal interface.

Can I download Systune now?

Systune is in development and is not available for public download yet. Join the waitlist for release news. The first 100 unique signups receive a free lifetime license for three Macs; codes are reserved now and sent when released.

How much will Systune cost?

The planned direct-download launch price is US$39 once for three Macs in one household, with two years of updates. The first-100 waitlist giveaway includes every future version. A 14-day full trial and a 30-day direct-purchase refund are planned for launch.

What happens before Systune removes a file?

A scan lists the proposed items before you select and confirm them. Cleanup categories have four risk levels; careful and dangerous categories are off by default. Protected system and credential paths are refused. User files can go to Trash; regenerable caches may be deleted in place. Permanent deletion cannot be undone, and a backup is still important.

Does Systune upload my scan results?

The Mac app processes scan results locally and has no analytics or crash reporting. License activation and manual license checks contact the license service; they do not send scan results. This website separately uses cookie-free PageHum analytics and stores the information needed for the waitlist and optional X sharing. See the Privacy Policy for details.

Which macOS versions will Systune support?

Systune targets macOS 14 Sonoma and later on Apple silicon and Intel. Development and testing currently use macOS 27. Release installation checks across supported systems and hardware are still part of the launch work.

Is a Mac App Store edition planned?

Yes. A separate Mac App Store edition is planned. Its sandbox-compatible features, final store pricing and release date are not confirmed. The current release pipeline packages the direct-download Mac edition.

Do I need Full Disk Access?

Only for the parts that require it, including some Safari, Mail and Messages data and the permission database read by the audit. Systune reports unavailable checks instead of treating unreadable settings as a pass. Administrator tasks require separate authorization.

How is Systune different from CleanMyMac, OnyX and DaisyDisk?

Systune focuses on reviewed cleanup, a 92-check security audit and 300 macOS settings in a shared Mac and terminal workflow. CleanMyMac also offers malware scanning and both subscriptions and one-time purchases. OnyX is free and includes cleaning, maintenance and settings controls. DaisyDisk focuses on visual disk analysis and supports remote cloud-storage scans. All three are available today; Systune is on a waitlist. Read the sourced comparisons to choose for your needs.

Is a security audit the same as antivirus?

No. Systune checks security and privacy configuration, such as FileVault, the firewall and sharing settings. It does not include a malware-detection engine and does not replace macOS security protections or a dedicated antivirus product. An audit score is a summary of checks, not a guarantee that a Mac is secure.

Is there a command-line version?

Systune includes a CLI with JSON output and a full-screen terminal dashboard built on the same Rust core as the Mac app. Review destructive operations before automating them. The iPhone companion is also in development; it controls your Mac over the local network.
