As of early 2026, the latest major version of CleanMyMac is 5.5.0 , not CleanMyMac X.

Subscriptions, on the other hand, cover all future major updates automatically.

The primary function of CleanMyMac X is to remove clutter from your Mac. It scans your system for various types of unnecessary files, including outdated caches, broken downloads, logs, and application leftovers, which often take up significant storage space. The "System Junk" module intelligently identifies and removes these files to free up space and improve performance. It also includes tools to find and remove large and old files, as well as duplicate files and similar photos, allowing you to better organize your storage.

The v4.15.0 update focuses on system optimization, clutter removal, and malware protection.

Legitimate optimization tools rely on constant cloud updates to maintain their malware definition databases and cleaning rules.
