MacOSCleaner Overview
MacOSCleaner is a free, native SwiftUI system cleaner and app uninstaller built specifically for Apple Silicon Macs. Smart Cleanup scans 1,887 known path definitions across 55 categories, covering caches, browsers, package managers, and developer tools from 275-plus apps and 86 toolchains, showing a risk badge for each item before anything gets removed. A forensic app uninstaller scans up to 5 levels deep using 30 evidence types to catch leftover files, backed by a standalone orphan scanner for remnants from apps removed long ago. A Duplicate File Finder uses SHA-256 verification to confirm exact matches, and a navigable Disk Space Analyzer reports honest APFS physical sizes down to the file level. On-device Apple Intelligence explains files and processes entirely offline, and Siri Shortcuts can trigger a scan or uninstall by voice. The app runs with zero telemetry and no cloud upload, and it's free for personal use under a source-available license.
Why Choose MacOSCleaner Mac App
Commercial Mac cleaners often charge an annual subscription and quietly run background processes the whole time. MacOSCleaner takes a different approach. A native SwiftUI app built specifically for Apple Silicon scans 1,887 known cache and leftover locations across 275-plus apps, then lets you review every file with a risk badge before anything gets deleted.
On-device Apple Intelligence explains what a file or running process actually is, entirely offline, and Siri Shortcuts can trigger a scan or uninstall by voice with zero background daemons. The app is source-available under GPLv3 plus the Commons Clause, meaning it's free to use personally but not open source in the fully permissive sense, and a separate commercial license applies for business use. Since releases aren't currently code-signed by Apple, the first launch requires a one-line Terminal command to clear Gatekeeper's warning.

Supported macOS Versions
MacOSCleaner requires macOS 26.0 or later, running on Apple Silicon Macs starting with the original M1. Scanning tens of thousands of files across 1,887 known paths is genuinely disk-intensive work, so a Mac with a faster SSD completes a full scan noticeably quicker than an older, more constrained system. The app takes advantage of multiple CPU cores by running its cleanup categories in parallel during a scan.
