MacCleaner Pro for Mac

Anyone familiar with macOS's built-in storage management will recognise the territory MacCleaner Pro works in, but the approach is different: instead of a single utility, Nektony ships a bundle of focused applications, each with one clear job.

Scanning your disk: find large files before the Startup Disk Full warning

• Disk Space Analyzer PRO maps storage use and locates large content, which helps when the Startup Disk Full warning begins to appear.
• Duplicate File Finder PRO searches for repeated files and folders, including duplicates buried inside iCloud folders.
• App Cleaner & Uninstaller PRO removes unused applications and manages extensions that otherwise linger in the background.
• Memory Cleaner monitors memory pressure and clears inactive RAM when the system feels sluggish.

Version 4.0.2: a quieter release

The current build focuses on refinement rather than new tools. Detection works better for items stored in a custom Home folder, interface issues have been smoothed over, and the bundle remains compatible with macOS 10.13 and later on both Intel and Apple Silicon machines.

Finder shortcuts: right-click any folder in the sunburst chart

Some of the most useful behaviour in MacCleaner Pro is deliberately quiet. In Disk Space Analyzer, right-clicking any folder in the sunburst chart opens a contextual menu that lets you reveal it in Finder immediately; no need to navigate back through the hierarchy. The same menu offers a quick filter for files above a chosen size, which turns the visual map into a targeted search in one click.

Memory Cleaner is installed as a menu bar companion by default, and its icon changes colour with memory pressure — green, amber, red — so you can read the system's state at a glance without opening the app. A single click on the icon purges inactive memory. Holding Option while clicking forces a deeper clean that also compresses memory, though this is rarely necessary unless you have just closed a particularly heavy application and want to reclaim every megabyte.

Duplicate File Finder remembers your last-used scan location and comparison method between sessions. If you repeatedly audit a media drive, reopening the app places you exactly where you left off, saving the few seconds of navigation that accumulate over weeks. Funter's Finder integration is similarly unobtrusive: it adds a toggle to the toolbar that shows or hides invisible files without opening a separate window, and the toggle remembers its state after a restart.

A workflow: clearing space before a large project

Suppose a video editor is about to ingest 200 GB of raw footage and the internal drive shows only 85 GB free. Opening Disk Space Analyzer first gives a visual overview: the largest blocks on the sunburst chart point to a forgotten media cache and a folder of screen recordings from six months ago. Right-clicking each sends the contents to the Trash after a quick sanity check, freeing 40 GB in under two minutes.

Next, App Cleaner & Uninstaller reveals three applications that were removed by dragging to the Trash months ago, each leaving behind a collection of service files totalling 11 GB. Selecting them and clicking Uninstall clears the remnants in one pass. A quick scan with Duplicate File Finder on the project archive drive uncovers four copies of a shared sound library — one in an old backup, two in test folders — which had been synced via iCloud and duplicated across directory structures. Marking the oldest versions for removal and verifying the file count recovers another 28 GB.

Finally, Memory Cleaner clears inactive RAM, but the real benefit at this stage is the menu bar indicator: it shows memory pressure dropping after the purge, confirming that the system is no longer holding stale allocations from the editing session earlier in the day. The whole sequence, from opening the first app to having 164 GB free, takes roughly eight minutes.

Launch speed: under three seconds even on a 2 TB volume

The bundle's applications launch quickly: Disk Space Analyzer opens in under three seconds on an Apple Silicon Mac, even when pointed at a 2 TB volume, because the initial scan is a fast enumeration of the file-system tree rather than a deep read of every byte. The deep analysis, when requested, runs on a background thread and does not block the interface.

Memory Cleaner's background agent uses negligible CPU time — typically 0.1% or less when idle — and its periodic sampling of memory pressure is light enough to leave no measurable impact on battery life during a workday. The one tool that can briefly tax the system is Duplicate File Finder during a checksum comparison across tens of thousands of files on a mechanical drive; the app keeps its interface responsive, but disk I/O rises noticeably. Pausing the scan from the toolbar returns the drive to normal within a second or two.

Duplicate overload: scanning the whole drive without a size filter

A frequent misstep is running Duplicate File Finder on the entire system drive without setting a minimum file size. This produces an overwhelming results list filled with tiny cache files and font duplicates that are functionally harmless and tedious to review. Limiting the scan to files above 10 MB, or targeting a specific folder like Documents or Downloads, yields a more manageable and actionable set of duplicates.

Another pattern is treating Memory Cleaner as a performance booster to run before every intensive task. On modern macOS, inactive memory is automatically reclaimed when needed; manually purging it too often can briefly slow down app relaunching because the system must reload data from disk rather than cached RAM. The tool is best used after closing heavy applications — video editors, virtual machines, large photo libraries — not as a preemptive ritual.

With App Cleaner & Uninstaller, a common oversight is ignoring the Extensions tab. Beginners often delete an application but leave its Finder extensions, Quick Look plug-ins or login items behind, which can cause odd behaviour weeks later. The Extensions panel lists these by category and makes removal a single-click action, yet it is easy to overlook because the app opens to the Applications view by default.

Version 4.0.2 brings three refinements rather than a feature parade: detection of items in iCloud folders has improved, the same applies to custom Home folders, and several minor interface issues have been corrected.

• macOS 10.13 or later
