See what's filling your disk. Reclaim it safely.

The free macOS cleaner that finds gigabytes of caches, logs, leftovers, and forgotten large files — then clears them safely. Trash by default, review-before-delete, and a hard denylist on system paths. 100% on-device, with deep developer cleanup built in.

What it cleans

Everything that quietly fills a Mac.

Six classes of reclaimable space, each understood and handled differently — from rebuildable caches to data you should move, not delete.

Caches & system junk

User and app caches, logs, and rebuildable temporary files across your Library — usually the biggest, safest space to win back.

User cachesApp cachesSystem logsTemp files

Large & old files

Surfaces the forgotten multi-gigabyte files and folders, biggest first, so you decide what stays.

Time Machine snapshots

Reclaim space held by local APFS snapshots that quietly hide from the Finder.

Local snapshots

Move to an external drive

Relocate big libraries — Photos, media, model files — with a verified copy and a symlink, so they still work.

Developer cleanup

Deep cleanup power users love: Xcode DerivedData, Docker, node_modules, Gradle and package caches.

iOS backups & emulators

Old iPhone backups and Android emulator images that pile up on disk unnoticed.

Before / after

From “startup disk almost full” to breathing room.

A typical full Mac: 485 GB used on a 500 GB drive. One pass of safe-to-clear junk and rebuildable caches gives most of it back — before you even touch movable data.

62.4GB

reclaimed in one scan — and another 112 GB of photos, media and archives you could move to an external drive.

Finds the hidden gigabytes

It finds space you'd never think to look for.

It scans your Mac the way a pro would — capacity first, then what's actually eating it — and sorts everything into junk, rebuildable caches, large files, and data worth keeping.

  • Caches, logs and temporary files across your Library — rebuildable and safe to clear
  • Forgotten large & old files surfaced biggest-first, plus reclaimable Time Machine snapshots
  • Every item gets a safety level and a clear delete / move / keep / review recommendation
Offload, don't delete

Out of space, but it's stuff you want to keep? Move it.

Big things you can't bear to delete — your Photos library, video projects, archives — get relocated to an external drive with a verified copy, then a symlink so everything still opens where it always did.

  • Copies with ditto, verifies the result, then removes the source — never the other way around
  • An optional symlink keeps the original location working, so apps don't notice the move
  • A failed or interrupted move cleans up after itself and leaves your originals untouched
Read every volume

Your disks, as flight instruments.

It scans the way you would by hand — df and diskutil for capacity, du for what's eating space — and renders each volume as a radial capacity gauge.

  • Near-full startup disks read critical; roomy external drives are flagged as offload targets
  • Standard macOS tools, no black-box magic — the scan is transparent and auditable
  • Live progress on every delete and move, down to per-file byte counts
Safe by design

It deletes files — so it's built to never delete the wrong one.

Cleaning a Mac is only useful if you can trust it. Four guarantees are baked into every action.

Trash by default

Every deletion goes to the macOS Trash — reversible until you empty it. Permanent delete is a separate, explicit opt-in inside the confirmation.

Hard denylist

System paths — /, /System, /usr, /bin, /Applications and your home root — can never be selected or deleted.

Review before delete

Nothing is removed automatically. You see every item, its size and a recommendation, and you confirm a manifest before anything happens.

100% on-device

All scanning and classification run locally. No accounts, no telemetry, no network calls. Your data never leaves your Mac.

FAQ

Questions, answered.

01Is it safe to use?
Yes. Deletions go to the Trash by default (reversible), system paths are on a hard denylist that can't be selected, and you review and confirm a manifest before anything is removed. Risky items, like cloud-synced folders, require an extra acknowledgment.
02What does it actually clean?
User and app caches, logs and temporary files, reclaimable Time Machine snapshots, and forgotten large & old files. It can also move big libraries (Photos, media) to an external drive — and includes deep developer cleanup like Xcode, Docker and package caches.
03Why does it need Full Disk Access?
macOS sandboxes folders like ~/Documents, ~/Desktop and parts of ~/Library. Without Full Disk Access the scan reads them as empty and undercounts. Granting it (System Settings → Privacy & Security → Full Disk Access) lets the scan see your real usage. It's used only locally, on your machine.
04Does it work on Intel Macs?
Not yet — Mac Disk Reclaim is Apple Silicon (arm64) only for now, on macOS 11 Big Sur or later. Intel support may come later.
05Is any of my data collected?
No. There's no telemetry, no analytics inside the app, no account and no network connection. Everything runs on-device and your data never leaves your Mac.
06How do I open it if macOS shows a warning?
The app is signed with an Apple Developer ID and notarized by Apple, so it normally opens with no warning. If you ever see one, right-click the app and choose Open, then confirm once.
07Will it delete something I need?
It recommends only safe-to-delete junk and rebuildable caches by default; real data is labeled “review” or “move,” never auto-selected. And because deletes go to the Trash, you can restore anything until you empty it.
08Is it free? What's the catch?
It's completely free — no pricing, accounts or upsells. Trust comes from Apple notarization and its on-device, no-telemetry design.
