Big Wins & Reclaim

Safely reclaim gigabytes without breaking build environments or system integrity.

✓ 104.2 GB of safe reclaimable space discovered in this scan.

Includes Xcode DerivedData, Docker VM reclaim, Simulator runtimes, and orphaned Application Support folders.

Designed for macOS Power Users

Everything you need to master your storage.

Traditional cleaners treat every file the same. DiskAtlas understands APFS shared blocks, developer artifacts, sandboxes, and modern macOS architecture.

Interactive Treemap & Drilldown

Visual nested blocks rendered with GPU acceleration. Zoom seamlessly from the root volume down to deep folder hierarchies in milliseconds.

Color by Kind Breadcrumbs Instant Zoom

Developer Big Wins Catalog

Spot Xcode DerivedData, CocoaPods caches, Docker overlay2 bloat, Cargo build artifacts, Python .venv environments, and node_modules taking up 50+ GB.

Xcode Docker Node & Rust

Leftover App Uninstaller

Dragging an app to Trash leaves gigabytes in Application Support, Group Containers, Caches, and Preferences. DiskAtlas deep-scans and purges orphans cleanly.

Sandboxes Application Support 1-Click Uninstall

APFS Clone Intelligence

APFS Copy-on-Write clones and hard links share physical disk blocks. DiskAtlas calculates logical vs unique bytes so you don't delete files that take 0 extra space.

Live Menu Bar Pulse Monitor

Track CPU activity, Memory pressure, and continuous Disk I/O right from your macOS menu bar. Get proactive alerts before your SSD runs completely out of room.

● Zero background drag: Pulse runs via lightweight Mach kernel ports using less than 0.1% CPU.

● Critical Path Guard: Built-in safeguards prevent accidental deletion of System, iCloud, or git head files.

The APFS Difference

Stop deleting files that take 0 extra bytes.

On macOS APFS volumes, duplicating a 50 GB video or Xcode workspace doesn't use 100 GB of disk. It creates a Copy-on-Write clone pointing to the exact same physical disk blocks.

Ordinary disk cleaners falsely report duplicate files and waste your time. DiskAtlas inspects shared block extents and shows you true Unique vs Shared storage.

Common Questions

Frequently Asked Questions

Got questions about permissions, compatibility, or privacy? We've got answers.

What versions of macOS are supported? +

DiskAtlas is a native SwiftUI app built for macOS 14 (Sonoma) and macOS 15 (Sequoia) as a universal binary for Apple Silicon (M1, M2, M3, M4) and Intel Macs.

Why does DiskAtlas request Full Disk Access? +

To map system caches, Time Machine snapshots, Mail attachments, and developer libraries across the entire volume accurately, macOS requires Full Disk Access. DiskAtlas never transmits any data—all scans occur 100% locally on your Mac.

Is my data private? Does DiskAtlas send telemetry? +

Zero telemetry. DiskAtlas has zero third-party tracking scripts, zero analytics SDKs, and zero cloud uploads. Your file paths, sizes, and disk layouts remain strictly on your Mac.

Can I use my Pro license on multiple Macs? +

Yes! A single DiskAtlas Pro license covers up to 3 personal Mac computers (e.g. your MacBook Pro, Mac Studio, and iMac).

How does DiskAtlas prevent accidental file deletion? +

DiskAtlas incorporates a Critical Paths Engine and SafeScore algorithm. macOS system components, active Git repositories, and core documents are strictly protected. Files are moved to the native macOS Trash rather than permanently purged, giving you instant recovery.
