CleanMaster
CleanMaster is a Mac cleaning utility from Any Case Solutions that scans for junk, duplicate, and large files to help free local storage.
What is CleanMaster?
CleanMaster is a macOS utility published by Any Case Solutions and distributed through the Mac App Store as a storage cleanup tool. It is designed to scan a Mac for removable clutter such as junk files, duplicates, similar photos, large files, and app-related leftovers, then present those results for manual review. Users typically encounter it when they are trying to recover disk space or simplify file management on a MacBook or desktop Mac. Based on its public app listing, the app focuses on local storage analysis rather than serving as a core system component. Because this type of software can access broad areas of user data while scanning the disk, its results should be reviewed carefully before removal actions are confirmed. It is not required for macOS to run, but it may be useful for users who actively use its cleanup and file-finding tools.

Safety overview
Status: Use with caution
This appears to be a legitimate third-party Mac cleaning app, not a built-in macOS component. It is generally safe when obtained from the Mac App Store, but cleaning tools can touch many user files and may suggest removing data you still want. Review scan results carefully, especially duplicates, app leftovers, and photo-related items, before confirming deletion.
Recommendation: Keep it only if you use its storage cleanup features and trust its scan results. If you do not use it, removing the app is usually reasonable because macOS does not depend on it. Before deleting anything through the app, verify the selected files manually.
