An All-in-One Tool to Manage Your Mac
Manage unused apps, startup items, resource-heavy activity, and duplicate or unnecessary files.
Compatible with Mac OS 13+ from 2017 and newer
Understand your Mac at a glance
Three simple scans cover the essentials: storage, system activity, and key health indicators such as battery and disk.
Review Storage Usage
Identify large files, duplicate items, and other data that may no longer be needed. All actions require your approval, giving you control over what is removed.
Evaluate System Performance
Review applications and startup items that may use significant system resources. Easily identify active processes and manage them directly.
Monitor System Status
View indicators related to disk usage and battery condition to help you make informed decisions about maintenance and backups. Clear summaries provide visibility into your Mac’s current state.
Manage Storage with Confidence
Review files located in your home folder and choose what to keep or remove. No changes occur without your approval.
Junk File Cleaner
Find caches, logs, and unused language files and clear space with your approval.
Over time, apps leave data you don’t need. Review the results and remove what you choose — nothing happens without your say-so.
Safety by design: nothing is removed automatically. Review, confirm, and undo if needed.
Large & Old Files
See what’s eating space and decide what stays or goes in a couple of clicks.
Quickly sort by size or age, preview what’s safe to remove, and keep what matters. Clear space without digging through folders.
Safety by design: nothing is removed automatically. Review, confirm, and undo if needed.
Duplicate Files
Find true duplicates and remove extras while keeping one safe copy.
CleanBuff compares files byte-for-byte to avoid false matches, then suggests safe removals you can confirm in one step.
Safety by design: nothing is removed automatically. Review, confirm, and undo if needed.

Questions, answers.

The free version lets you scan your Mac, see what can be cleaned, and explore key features so you understand exactly what CleanBuff finds.
What do I get with CleanBuff Pro?
CleanBuff Pro includes expanded cleaning features, additional management tools, and fewer usage limits compared to the free version.
