Clutterscope
Duplicates, by content
Files are matched byte for byte: same size, then a SHA-256 of the first 64 KB, then of the whole file. Pick the copy to keep and the rest are staged.
Disk space analyzer for macOS
See what’s filling your Mac, then clear it safely.
Clutterscope scans a drive in seconds, draws it eight different ways, and finds the caches, build output, duplicates and app leftovers you forgot about. Nothing is removed until you say so.

One scan, eight views
Read the same disk the way the problem needs.
Every view is the same scan, so you can switch instantly. Click to select, double-click a folder to focus on it, and zoom in until the labels you need appear.
Folders
Each subfolder is a card with its size, share of the parent and its three dominant file types. Prefer a list? One click switches to an expandable tree.
Best for walking down from the top until you find it.
Sunburst
Rings radiate out from the scan root. Each ring is one level deeper and each arc is sized by bytes, so the heaviest branches jump out.
Best for seeing the whole disk’s shape at once.
Flame
Depth runs top to bottom and size left to right, so a long chain of nested folders reads like a stack trace.
Best for deep paths such as build output and app containers.
Bubbles
Nested circles, one per folder, with area proportional to bytes. Big things look big, even when they hide among thousands of small ones.
Best for spotting the few giants in a crowded folder.
Mind Map
The heaviest branches radiate from the root with a size on every node. Labels are placed so they never overlap.
Best for explaining where the space went to someone else.
Top Sizes
The hundred largest files or folders, ranked, each with its location. Stage every file over 1 GB in one click.
Best for quick wins when you just need space back.
Age Map
Bytes by last-modified age, a month-by-month heatmap, and Big & Untouched: large files you haven’t opened in over a year.
Best for finding what’s old, not just what’s big.
Treemap
Every file is a rectangle sized by bytes, nested inside its folders. Pinch or ⌘-scroll to zoom, and more labels appear as you go.
Best for dense folders holding thousands of files.
Find the weight, then clear it
Tools for the things that actually fill a Mac.
Quick Wins, ready the moment a scan lands
Clutterscope totals the usual suspects as soon as the scan finishes, each with a plain explanation of what it is and whether it comes back.
- Caches and logs, Downloads and the Trash
- Xcode DerivedData, and iOS Simulators listed by device name, not UUID
- node_modules and build folders, counted only when a project file sits beside them
- Video and audio over 250 MB
DerivedDataCoreSimulatornode_modules.buildtargetdist.next
Uninstall apps and everything they left behind
Each app is listed with its true footprint: the bundle plus the caches, preferences, HTTP storage, logs and containers it scattered across ~/Library.
- Uninstall Completely stages the whole set in one click
- Untick any leftover you want to keep
- If the app is running, Clutterscope offers to quit it first
- Apps that are part of macOS can’t be removed
A cleanup list you review before anything moves
Add to Cleanup puts items on a list, not in the bin. Review the whole set, then move it to the Trash in one step, where it can be restored until you empty it.
- System-critical locations are refused when you stage and checked again at removal
- Staging a folder absorbs anything already staged inside it
- App containers need Full Disk Access, and the list tells you so up front
Snapshots you can compare
Save a scan and hold it against a later one to see exactly which folders grew while you weren’t looking. In the example, Docker’s disk image grew by 18 GB in three months.

CPU, memory, network and free space stay in view, with the processes doing the work ranked underneath.
How it works
From download to disk space in five steps.
-
Install and activate
Open the disk image and drag Clutterscope into Applications. It’s signed with a Developer ID and notarized by Apple, so macOS checks it and opens it after the usual one-time confirmation.
On first launch, paste the licence key from your purchase email and choose Activate. You do this once on each Mac.
-
Allow Full Disk Access
macOS keeps Mail, Messages, Safari and other apps’ containers private. A guided sheet opens the right Settings pane, lets you drag the app straight into the list, and notices the moment you switch it on.
Optional. Without it, protected folders are counted as unreadable and everything else works.
-
Choose what to scan
Your whole Mac, your home folder, any folder, or an external or network drive. Top-level folders fill in on screen as each one finishes, and recent scans remember their size for next time.
⌘N Scan Full Mac⌘O Scan Folder⌘R Rescan
-
Read the map
Switch views, hover for sizes, double-click a folder to focus on it, and zoom until the labels you need appear. The inspector shows size on disk, logical size, APFS compression savings, file counts and dates for anything you select.
⌘1–⌘8 Views⌘= ⌘− Zoom⌘↑ Enclosing folder
-
Clear the weight
Add anything to Cleanup, from a view, Quick Wins, Duplicates or an app’s footprint. Review the list, then Move to Trash. Nothing is ever deleted in the background.
⌘⌫ Add to Cleanup⇧⌘C Open Cleanup
Safety and privacy
Nothing leaves without you.
Staged, never silent
Items move only when you press Move to Trash, and they go to the Trash, not straight to deletion.
Protected by default
The places macOS depends on can’t be staged at all. The rules are checked when you stage and again right before removal.
Private by design
Scanning, hashing and duplicate matching all run on your Mac. There’s no account, no sync and no analytics. The only connection is a licence check once a day, which never includes your files or scan results.
Signed and notarized
Every release is signed with a Developer ID and notarized by Apple.

Questions
Answered.
Can Clutterscope delete something I still need?
Not on its own. Items are staged on a list you review first, and Move to Trash sends them to the Trash, where you can restore them until you empty it. System-critical locations can’t be staged at all.
Why does it ask for Full Disk Access?
macOS keeps Mail, Messages, Safari data and other apps’ containers private. With access, those folders are counted and app leftovers in containers can be removed. Without it, everything else still works and protected folders show as unreadable.
Does it send anything off my Mac?
Never your files or scan results. Scanning, hashing and duplicate matching happen locally, and there’s no account, no sync and no analytics. The app connects only to check its licence: when you activate, and then once a day while you’re online. That check sends the activation code, a one-way code that identifies the Mac, and the Mac’s name.
How does the licence work?
You pay ₹499 once and the licence is yours for life. It works on any Mac, one Mac at a time. After activation Clutterscope works without an internet connection; when your Mac is online it checks the licence once a day.
I have a new Mac. How do I move my licence?
Enter your key on the new Mac. Clutterscope tells you which Mac is using it and offers Move to This Mac. The old Mac stops working the next time it goes online. You can also free the key first from Settings, Licence, Deactivate This Mac.
I lost my licence key.
Use Lost your key? below with the email address you bought with, and every key bought with it is emailed to you again. On a Mac that’s already activated, the key is also in Settings, Licence.
Can I scan external and network drives?
Yes. Scan your whole Mac, your home folder, or any folder or mounted volume, including external SSDs and network shares. A scan stays on the drive you chose, so nothing is counted twice.
How does it find duplicates?
By content, not by name. Files of the same size are compared by a SHA-256 of their first 64 KB, and only candidates that still match are hashed in full. Files under 64 KB are skipped by default; you can change that in Settings.
Are hard links counted twice?
No. A file with several hard links occupies its space once, so Clutterscope counts its bytes once, which keeps totals honest for things like Homebrew and Git object stores.
What does the inspector show?
For any selection: size on disk and logical size, how much APFS compression saved, file and folder counts, its share of the parent folder, created, modified and last-opened dates, and the largest items inside.
