If you’re a Mac user, you’ve likely encountered the mysterious “System Data.” That consumes gigabytes of storage for no apparent reason. You’ve deleted downloads, trash, and browser caches. But your disk remains full. This is where Dr.Buho’s BuhoCleaner enters the scene — a powerful and user-friendly app that promises to Clear System Data on Mac, reclaim valuable space, and boost overall performance.
In this review, we’ll summarize all you need to know about BuhoCleaner, from its best features to its real-life usability, performance, and if it’s worth the install on your Mac.
What Is Dr.Buho BuhoCleaner?
BuhoCleaner is a utility tool macOS app developed by Dr.Buho solely for the purpose of cleaning out junk files, deleting system clutter, and improving your Mac’s speed and storage health. The app is aimed at the areas most people find it impossible to clean by hand — such as system caches, traces of unused apps, and logs.
Compatible with Intel and Apple Silicon Macs (M1, M2, M3, and M4), BuhoCleaner has optimized efficiency and ease of use, yielding expert-quality cleanup in the least amount of clicks.
Interface and Ease of Use
One of the most attractive features of this is its simple interface. When launched, users are presented with a plain dashboard. By featuring such options as “Flash Clean,” “App Uninstall,” “Large Files,” “Duplicate Files,” and “Startup Items.” Each category is self-explanatory and doesn’t need to be learned. Which makes it ideal for beginners and power users both.
Flash Clean is the star feature, providing a fast scan of system junk including:
- Cache files
- Log files
- Temporary system files
- User trash
- Xcode junk (for developers)
In less than a minute, it identifies what’s safe to delete and how much space will be freed up.
Core Features of BuhoCleaner
1. Flash Clean
This tool scans your entire Mac and removes junk files that take up unnecessary space. From system logs to app leftovers, Flash Clean handles it all swiftly.
2. App Uninstall
Dragging apps to the Trash doesn’t completely remove them — residual files stay behind. BuhoCleaner’s uninstaller ensures complete deletion, including caches and library files.
3. Large & Duplicate Files Finder
With these tools, you can detect and remove files that are large in size or duplicated across folders — especially helpful for media-heavy users.
4. Startup Item Manager
Speed up your boot time by managing which applications launch at startup. Disabling unnecessary ones makes a noticeable difference in performance.
5. Disk Space Analyzer
Visualize your disk usage with easy-to-read charts and file/folder breakdowns. It helps identify what’s hogging your space at a glance.
6. RAM Cleaner
Free up memory in real time without restarting your Mac — useful when multitasking or running resource-intensive apps.
Performance and Efficiency
BuhoCleaner lives up to its promise of being lightweight yet effective. A typical full system scan takes under two minutes. Unlike some bulky cleaners, it doesn’t slow down your system while running. In our test, we recovered over 10GB of space in one scan — most of it from hidden caches and old system files.
Importantly, it takes a non-destructive approach — meaning it won’t remove files critical to system performance or stability. Each file selected for removal is previewed first, giving you control over what stays and what goes.
