Startup-disk scanning
Walks the whole startup volume, including firmlinked Data paths, while skipping other mounted drives, with live file counts, bytes and the current location as it runs.
A macOS storage utility that scans your startup disk, shows where the space went and only cleans up what you have reviewed. Built with Electron, React and a native scanning engine, all running locally on your Mac.

Find and remove unneeded files across your startup disk.
Scan againStorage tools handle personal files, so every screen has to make its action understandable. MacUtility turns a raw disk scan into categories, searchable detail and context you can act on.
Walks the whole startup volume, including firmlinked Data paths, while skipping other mounted drives, with live file counts, bytes and the current location as it runs.
Real disk capacity beside a colour-coded ring and five categories: Large Files, Installed Apps, Downloads, Junk Files and Other Files.
Find scanned files and apps by name, inspect their size and metadata, and reveal anything in Finder without leaving the app.
Discovered application bundles with their scanned sizes. Supported whole bundles can be reviewed and moved to the Trash.
A size-sorted directory hierarchy with a proportional storage visualization, built from the existing scan instead of starting a new one.
Cache and log cleanup, plus Homebrew, npm, Go and Docker maintenance that shows the exact command and its consequences before it runs.
Every item gets a risk level decided by the trusted desktop process, and every cleanup runs through the same eight-step pipeline, so nothing is removed on a guess.
Eligible caches and logs in your own ~/Library. Apple-managed com.apple.* folders are always excluded.
Downloads, leftover installers and supported app bundles. Each needs an explicit selection and explains the consequence.
System-owned apps go through the standard macOS password dialog. MacUtility never receives the password.
The same React interface runs inside a locked-down Electron app with real filesystem access, and inside a browser build backed by simulated data. The renderer never sees a file path. It works with opaque IDs the desktop process resolves and validates.
Deleting files is stressful. The interface trades urgency for clarity: soft colour, plain language and a visible consequence for every action.
Cleaner apps often lean on alarms and urgency. Cream surfaces, pastel charts and calm copy make storage feel approachable instead of stressful.
Nothing disappears from a single click. Selected paths, risk labels and consequences appear in a final review that needs explicit confirmation.
Removals can be restored until the Trash is emptied. Permanent deletion is a deliberate opt-in in Settings.
Storage totals are labelled as measurements, not promises of recoverable space, and incomplete scans show which paths were skipped and why.
The desktop app and browser demo import the same components, so this portfolio preview is the real product rather than a mock-up.
Labelled controls, status announcements, visible focus rings and reduced-motion support live in the shared components.
Every colour is a semantic token, so a theme swaps without touching layout, and this page follows along.
The browser demo is the real interface on simulated storage. Scan, browse categories, review a cleanup and switch themes without touching your files. The desktop app does it for real.
Not sure which Mac you have? Apple menu → About This Mac shows a Chip (Apple Silicon) or Processor (Intel). Open the DMG and drag MacUtility to Applications. Free builds are not notarized by Apple, so macOS may ask you to confirm before opening. Apple's guidance explains how.
Scans and cleanup stay on your Mac: no accounts, no telemetry, and files or scan results are never uploaded. The app only checks GitHub for newer releases.
Cleanup can cause data loss. Keep a current backup and review selected items before removing anything. Official builds are licensed for personal, non-commercial use.
