Cleaner One Pro
Cleaner One Pro is a macOS utility from Trend Micro that helps you find junk files, duplicate files, large files, and removable clutter to free disk space.
What is Cleaner One Pro?
Cleaner One Pro is a Mac cleaning and storage-management app for users who want to reclaim disk space and review files that may no longer be needed. It helps organize storage by scanning for junk files, duplicate files, large files, and leftover files from removed apps, then presenting results for manual cleanup. The app also includes tools for reviewing installed apps and checking storage use so you can decide what to keep on your Mac. Its features are aimed at everyday maintenance rather than antivirus protection, making it most useful for people who want a clearer view of disk usage and easier cleanup workflows. Cleaner One Pro is published by Trend Micro and is designed for macOS.

Safety overview
Status: Mostly safe
Cleaner One Pro is a legitimate disk-cleaning utility, but apps in this category can affect personal files if cleanup items are selected carelessly. Access to files and folders is consistent with its purpose because it needs broad file visibility to scan for duplicates, large files, and junk. Before deleting scan results, review anything in Documents, Downloads, Photos libraries, mail data, cloud-synced folders, or external drives to avoid removing files you still need. If you use app-removal features, confirm the app and related data are truly no longer required.
Recommendation: Keep Cleaner One Pro if you actively use it to manage storage and you are comfortable reviewing cleanup results before removal. If you do not use Mac cleaning tools, you can remove it without affecting normal macOS operation. When using it, treat scans as a review list rather than deleting everything automatically.
