Take a look

Less hunting through folders.

See what’s taking up space.

The biggest files and folders stand out on the storage map. Open a block to see what’s inside.

SpareDisk window showing a treemap of a home folder. Library is the largest area with its size on disk shown beside its logical size, then Downloads, Movies, SuperNotes.app and Documents, each cell labelled with its size.

Follow the big folders.

Big files take up big blocks. Click into a folder to see what’s inside, or switch to a sunburst or list.

Sunburst view of a home folder: the inner ring shows Library, Downloads, Movies and Documents in proportion to their size, the outer ring shows what is inside each, and the center shows the total and item count.

Videos, installers, or years of projects?

Group files by type to see what’s taking up space. Then open a category and start with its biggest files.

File Types screen: a bar of bytes by kind led by Developer and Archives and Installers, category chips with totals, and a list of the largest files with their kind and location.

Find large files.

A disk image can report 68 GB while occupying just 2 GB. See both sizes before deciding what’s worth removing. How to find large files →

Large Files screen as a map: Docker.raw at 68.72 GB but 2.16 GB on disk, Xcode_26.xip 3.52 GB, iOS 26 Simulator.dmg 2.86 GB, Backup 2019.zip 2.64 GB and other files above 500 MB.

That backup from 2019.

Find large files you haven’t changed in years. Check what’s still useful and what you’re ready to let go.

Older Files screen with a bar chart of bytes by modification year, Before 2023 through 2025, and a map of the oldest files led by Backup 2019.zip at 2.64 GB.

Find duplicate files.

SpareDisk compares file contents to confirm duplicates. Choose the copy to keep, then review the rest. How to remove duplicates →

Duplicates screen listing a group of two identical 40 MB PDF files in Downloads and Documents, a chosen keeper and a Stage the Rest for Review button.

Uninstall apps completely.

See an app alongside the related files found in your Library. Choose what goes to Trash; uncertain matches start unchecked. How to uninstall Mac apps →

Uninstall sheet for SuperNotes: the app is checked, its container and cache matched by identifier are checked, an Application Support folder matched by name only is unchecked, with a total and an Add to Review button.

The app is gone. Its files might not be.

Find leftovers from apps you’ve removed, grouped together so you can check them before sending them to Trash.

Leftovers screen listing data from apps that are no longer installed, grouped by identifier: Retouch 545 MB across a container, cache, saved state and preferences, BuildTool 241 MB, Ledger 76 MB and Weather 26 MB, each with a Move to Trash button.

Review what you remove.

Check your selection before moving it to Trash. Changed files are skipped, with a reason. You decide when to empty the Trash.

FAQ

Mac disk cleanup questions.

Can it scan my whole Mac?
You choose which folders and drives SpareDisk can access. It doesn’t ask for Full Disk Access or scan protected system areas.
Does it delete anything automatically?
No. You confirm every move to Trash. SpareDisk checks the files again first and reports anything it skips. You empty the Trash in Finder.
Can it remove every trace of an app?
It finds related data in your Library for you to review. System extensions and other privileged components need the app’s own uninstaller.
Will it run on my Mac?
SpareDisk requires macOS 15 or later and supports both Apple silicon and Intel Macs.
How do I free up disk space on my Mac?
Start with what is largest: see which folders use the most space, then check large and old files, duplicate downloads, developer caches and data left by apps you removed. Empty the Trash when you are done. Read the full guide.
What is System Data on Mac, and can SpareDisk clear it?
It’s mostly caches, snapshots, virtual memory and app data. SpareDisk shows the parts in folders you add, such as caches in your Library, and leaves protected system areas alone. What System Data is.
How is SpareDisk different from DaisyDisk, CleanMyMac or GrandPerspective?
SpareDisk is $4.99 once, with no subscription. It adds duplicates, app uninstall, leftovers and developer caches to the disk map, and it runs sandboxed without Full Disk Access. Compare with DaisyDisk, CleanMyMac or GrandPerspective.
Can it clear Xcode DerivedData and other developer caches?
Yes. The Developer screen measures Xcode, simulator, Homebrew, npm, Docker and other tool caches, and stages the rebuildable ones for review. Developer cache guide.
