Your Mac and your data is safe while cleanup

Cleanup and maintenance of your Mac are quite sensitive processes that require exceptional accuracy and reliability of the software. If you allow your cleaning application decide on your system and user data, you must be sure it's treated wisely and carefully. And that's exactly what CleanMyMac X does.

Safety Database

Years of experience allowed us to create a reliable Safety Database that contains a long list of rules and exceptions for all cleanup occasions. It takes into account peculiarities of the current operating system and provides instructions on certain apps. The database is constantly extended with new items and rules to prevent cleaning mishaps and keep all your data intact.

Smart Scan and Smart Selection

Smart Scan is a core tool of CleanMyMac X that starts the Cleanup, Protection, and Speed scanners (or Large & Old Files if you have the App Store version of CleanMyMac). They use intelligent algorithms and Safety Database to filter out unneeded, outdated, and possibly dangerous items that you can safely remove.

If you use CleanMyMac modules separately, the amount of items that can be painlessly erased is marked as smart-selected on a summary screen:

By default, CleanMyMac X offers to remove only automatically generated data related to system and app processes. None of your personal files is gone unless you want it.

Ignore List

CleanMyMac X continues updating its Safety Database and gets smarter with every new version. However, there might be something it doesn't know about your preferences. For example, you may want to ignore certain files or logs in cleaning modules, or you may need to hide some apps from the Updater module (not available from the App Store).

CleanMyMac X lets you create an ignore list for the following modules: System Junk, Photo Junk, Mail Attachments, iTunes Junk, Malware Removal, Updater, Large & Old Files, and Uninstaller.


Photo Junk and Updater modules aren't available from the App Store.

To add items to the ignore list, do these:

  1. Switch to a module that supports the Ignore List functionality.

  2. Control-click an item you want to hide from the scan results and choose Add to Ignore List.

To make your items visible in the scan results, open CleanMyMac X Preferences and remove corresponding items from the Ignore List tab.

Protection against malware

Starting from the X version, CleanMyMac has learned to detect and dispose of potentially harmful items like viruses, malware, spyware, and miners. It has got both a malware scanner and a real-time monitor (not available from the App Store) that verifies new installations even when CleanMyMac is off.

The malware scanner works either as a stand-alone Malware Removal module or as part of Smart Scan. It includes mostly open-source libraries, but we keep on updating it with new entries every week.
