Bottom Line: CleanMyMac X (developed by MacPaw) is legitimate, notarized by Apple, and 100% free of malware. However, use caution. Its background monitoring daemons consume CPU and RAM resources, and its automated ‘System Junk’ scanner can occasionally delete language localization files, Xcode simulator data, or user app preferences.
Is CleanMyMac X Safe for macOS?
CleanMyMac X is one of the most popular third-party utility applications for Mac. While it is safe from a security standpoint (notarized by Apple’s gatekeeper), power users and IT professionals hold mixed opinions on whether it is necessary.
1. Pros of CleanMyMac X
- Beautiful User Interface: Provides a 1-click visual dashboard for cache cleaning, app uninstallation, and disk space visualization.
- App Uninstaller Tool: Removes leftover preference files (
~/Library/Preferences) when deleting Mac applications. - Space Lens Visualizer: Helps visually identify large hidden folders on your SSD.
2. Cons & Risks of CleanMyMac X
- Background Resource Overhead: Runs persistent background menu bar daemons (
CleanMyMac X Health Monitor) that consume RAM and battery life on MacBooks. - Aggressive Batch Purging: Its automated System Junk scanner may purge Xcode caches or user settings files that you didn’t intend to delete.
- Subscription Price: Costs $39.95/year, whereas native macOS storage management tools are 100% free.

Is CleanMyMac X Worth Buying?
If you want a polished 1-click GUI tool and don’t mind a paid subscription, CleanMyMac X is convenient. However, you do not need CleanMyMac X to keep your Mac fast and clean. You can achieve the exact same storage savings for free using Terminal commands (rm -rf ~/Library/Caches/*) and native System Settings > Storage management.
