After 100+ hours of benchmarking, CleanMyMac X remains the undisputed leader. It reclaimed an average of 42GB on our test MacBook Air M2. The interface is intuitive, and every action is Apple Notarized for safety.
OnyX isn't just a cleaner; it's a deep-system maintenance tool. While CleanMyMac X focuses on simplicity, OnyX provides granular control over disk structures, cache hidden settings, and database rebuilding.
Verdict: It’s free and powerful, but lacks the polished automated guardrails found in paid alternatives. Perfect for developers and IT professionals.
We use a baseline MacBook Air M2 (8GB RAM) and a Mac Studio M2 Ultra (64GB RAM) running the latest macOS Sequoia, pre-loaded with 50GB of intentional system junk and duplicates.
Every app is audited for Apple Notarization. We monitor all outbound network traffic during scans to ensure no private data is transmitted to third-party servers.
We rank tools based on GBs reclaimed per minute of scan time and the subsequent impact on boot speed and application launch times.
