AI Summary

Mac Clean is a free, open-source macOS app that helps everyday Mac users clean junk files, remove malware, uninstall apps completely, optimize performance, and visualize disk usage — all from a single beautiful interface. It works like a one-stop shop for Mac maintenance, offering a Smart Scan that checks everything at once, individual modules for targeted cleanup, and a real-time menu bar monitor. The app is built with Swift and SwiftUI, stores no data about users, and never shows ads or subscriptions.

What is MacClean?

MacClean is a free, open-source Mac maintenance app that combines cleanup, malware scanning, optimization, and app uninstallation into a single SwiftUI interface. It targets macOS 14+ and positions itself as a transparent, subscription-free alternative to CleanMyMac. The app scans for system junk across 16 categories, detects malware using signature-based rules, manages login items and launch agents, finds duplicate files via progressive SHA-256 hashing, and includes a disk treemap visualizer called Space Lens. A separate menu bar monitor displays real-time CPU, memory, disk, and battery stats. Installation is a single Homebrew command or DMG download.

Why is it gaining traction?

The hook is straightforward: a feature-complete CleanMyMac replacement that costs nothing and shows you exactly what it does. The malware scanner is unusual for open-source cleaners -- most alternatives skip it entirely. The 10-level uninstaller that traces app remnants across 17+ Library subdirectories is genuinely thorough. The maintainers are refreshingly direct about tradeoffs: no Apple notarization because they won't pay the $99/year Developer ID fee, and honest disclosure that test coverage sits around 15-20% with safety-critical paths barely covered. That transparency builds trust.

Who should use this?

Developers and power users who want a native macOS cleanup tool they can audit themselves. Privacy-conscious users who object to CleanMyMac's telemetry and subscription model. Anyone running macOS 14+ who wants disk space analysis, duplicate detection, or a malware scanner without paying for commercial software. Not recommended for users who need notarized, Gatekeeper-approved builds out of the box.

Verdict

MacClean is a serious project with a clear vision and the technical chops to back it up. The credibility score of 0.8999999761581421% reflects its early stage -- 11 stars and modest test coverage mean it's not production-hardened yet. That said, the architecture is sound, the safety model is well-thought-out, and the maintainer's transparency about weaknesses is a good sign. Worth installing on a secondary machine to follow along, or contributing tests if you want to shape a genuinely useful open-source tool.
