A Mac that has run out of disk space slows down in small, frustrating ways, from longer app launches to failed system updates. To find the tools that actually fix it, we installed and ran more than 20 Mac cleaner apps on an M2 MacBook Air running macOS, loaded with the real clutter most people accumulate: bloated caches, app leftovers, duplicate photos, and old downloads. The eight apps below are the ones our team kept reaching for, ranked by how much they free up, how safely they do it, and what you pay.

We grouped free and paid options together so you can match a cleaner to your budget and comfort level. Some are one-tap, all-in-one suites; others are precise, single-purpose tools you control by hand.

The 8 Best Mac Cleaner Software in 2026

Below is the full breakdown of each app: what it does well, where it falls short, and what it costs. We lead with our overall pick and close with the cheapest and most specialized tools.

1. CleanMyMac (Best Overall)

CleanMyMac from MacPaw was the app our team reached for most often, and it is the one we would recommend to anyone who wants a single button that handles almost everything. Its Smart Care routine runs one scan covering system junk, malware, and performance, then walks you through what it found before removing anything.

When we ran Smart Care on our test machine, it cleared out gigabytes of system junk and cached files without flagging anything we needed to keep. The app uninstaller is the other standout: it removes apps along with their scattered app leftovers, the kind of cleanup macOS does not do on its own.

Key Features

CleanMyMac combines system junk and cache cleanup, malware detection and removal, an app uninstaller with leftover removal, a duplicate and similar-photo finder, cloud storage cleanup, memory and performance optimization, and a software update manager. MacPaw states the app is Notarized by Apple, which means Apple has scanned it for malicious components.

It requires macOS 11 or later, so it covers any reasonably modern Mac. On its own page, MacPaw reports a rating of 4.9 stars across 539 reviews, though that figure is the vendor's own, not an independent aggregate.

Pros & Cons

Pricing

CleanMyMac starts at $39.95/year for 1 Mac, which works out to from $3.33/month on annual billing. MacPaw also advertises multi-Mac tiers, including a plan listed around $63.95/year for 2 Macs and $127.95/year for 5 Macs, though we saw those multi-Mac prices only through store search snippets and would confirm them on the MacPaw store before buying.

2. MacBooster

MacBooster from IObit takes the all-in-one approach and adds a security angle, bundling cleanup, optimization, and a malware scan into one app. If you want one purchase that promises to clean and protect, it is a reasonable middle-ground option.

On our test machine, its system junk cleanup and large-file finder surfaced the same big offenders our top picks did, and its startup optimization trimmed a few forgotten launch items. The security scanning is a bonus, though not a replacement for a dedicated antivirus.

Key Features

MacBooster offers system junk cleanup, a virus and malware scan, startup optimization, a large and old file finder, a duplicate finder, an app uninstaller, memory cleanup, and privacy protection. Its macOS minimum is listed inconsistently, with some sources citing macOS 10.9 and others a much newer build, so confirm compatibility on the official spec page before installing.

A free 14-day trial scans and identifies issues, but you need a license to actually fix them, according to third-party reviews we cross-checked.

Pros & Cons

Pricing

MacBooster Standard is $39.95/year for 1 Mac (down from a $59.95 list price), the Premium tier is $59.95/year for 3 Macs, and a 5-Mac plan runs $89.95/year. Every tier is backed by a 60-day money-back guarantee, which is generous and gives you time to test it fully.

3. CCleaner for Mac (Best Free Option)

CCleaner for Mac is the name most people know from Windows, and its Mac version is the free cleaner we trust most for everyday tidying. The free version handles the basics well: it clears clutter, finds duplicate files, uninstalls apps, and manages startup items.

In our testing, the free tier was enough for a routine cleanup, clearing browser caches and junk files without nudging us toward a purchase on every screen. The privacy cleaning is a useful extra if you share a machine.

Key Features

CCleaner for Mac covers junk and cache removal, a duplicate file finder, an app uninstaller, photo analysis for blurry and duplicate images, browser and privacy cleaning, and a startup item manager. The official spec sheet lists support for macOS 10.12 (Sierra) through macOS 13 (Ventura) at the time we checked, so newer macOS support is likely but is not stated on the page.

The paid Professional Plus tier covers 3 devices and bundles the PC and Android versions, useful if you run more than one platform.

Pros & Cons

Pricing

The free version is the main draw. The paid Professional tier costs around $30-40/year for 1 Mac, depending on the seller and whichever intro discount is running, so we would treat the exact number as a moving target and check the current price at checkout.

4. DaisyDisk (Best for Visual Storage Analysis)

DaisyDisk does one thing and does it beautifully: it shows you exactly what is eating your disk space. Instead of a list, it draws an interactive ring map where the biggest files and folders take up the most space, so you can spot a forgotten 40 GB video archive in seconds.

When we pointed DaisyDisk at our cluttered test drive, it scanned the full disk in moments and made it obvious where our space had gone. You drag the items you do not want into a collector and delete them in one move, which keeps you in control of every removal.

Key Features

DaisyDisk provides a visual ring and sunburst disk map, a fast full-disk scan, support for internal, external, SSD, and cloud drives, an admin scan that reaches hidden files, system-file protection, and a drag-to-delete collector. It requires macOS 10.13 or newer and runs natively on both Apple silicon and Intel Macs.

A free trial lets you scan and visualize your disk; deleting files typically requires the paid license, so confirm the trial's deletion limits first. Independent reviews describe the app as notarized and sandboxed by Apple.

Pros & Cons

Pricing

DaisyDisk is $9.99 one-time, a lifetime license with no subscription, and it covers up to 5 personal Macs per license. It is backed by a 30-day money-back guarantee, which makes it an easy, low-risk recommendation.

5. Drive Genius

Drive Genius from Prosoft Engineering is less about clearing junk files and more about keeping your drive healthy. It is aimed at people who want to monitor drive health, repair disk problems, and benchmark performance, with cleanup as a secondary feature.

In our testing, its DrivePulse monitoring quietly watched the drive in the background and its duplicate finder cleared real space, but the app leans toward maintenance and repair rather than one-tap cleaning. If you have ever lost a drive without warning, the early-warning monitoring is the reason to consider it.

Key Features

Drive Genius includes drive health monitoring through DrivePulse, a malware scan, disk repair, a duplicate finder, a secure data shredder, performance benchmarking, drive cloning, and defragmentation for HFS+ drives. The official page lists support for macOS 10.12 and later, so verify the current build's top-end macOS support before buying.

It is the most maintenance-focused tool here, better suited to power users and small studios than to someone who just wants to free up space.

Pros & Cons

Pricing

Drive Genius costs $79/year for the Standard plan (up to 3 computers) and $299/year for the Professional plan (up to 10 computers). There is also a $99 one-time perpetual license per computer, though that version does not include future-macOS feature updates.

6. Disk Drill

Disk Drill from CleverFiles is best known as a data recovery tool, but it bundles a genuinely useful set of free cleanup extras alongside it. If you want one app that can both recover deleted files and help you free up space, it is a smart two-in-one pick.

During testing, its disk space visualizer and duplicate finder matched what the dedicated cleaners surfaced, and its S.M.A.R.T. drive health monitoring added an early-warning layer for free. Recovery is the headline feature, but the cleanup tools are not an afterthought.

Key Features

Disk Drill leads with data recovery and adds a free disk space visualizer and cleanup tool, a duplicate finder, byte-to-byte backup, S.M.A.R.T. drive health monitoring, and a data-protection feature called Recovery Vault. Its v6.2 download page lists support for macOS 10.15.8 through the current macOS release, which we would confirm on the official spec page.

The free version recovers up to 500MB of data and includes the cleanup and disk-space tools at no cost, so it is worth installing even if you never pay.

Pros & Cons

Pricing

Disk Drill Pro is $89 one-time and covers up to 3 computers. There is also an optional lifetime-upgrade add-on advertised at around $19, though we saw that figure in review coverage and would confirm it on the CleverFiles store.

7. OnyX (Best Free Power-User Tool)

OnyX from Titanium Software is the free tool we recommend to people who like to know exactly what their software is doing. It is a maintenance utility that runs the same kinds of cleaning and repair scripts macOS uses internally, plus a deep set of hidden system tweaks.

In our testing, OnyX cleared caches, rebuilt system databases, and let us configure hidden Finder and Dock settings that no graphical app exposes. It is completely free, supported by optional donations, which is remarkable for how much it can do.

Key Features

OnyX can verify the system file structure, run maintenance and cleaning scripts, delete caches, rebuild databases and indexes, uninstall apps, configure hidden Finder, Dock, and Safari parameters, and remove problematic files. Titanium Software ships version-specific builds, including OnyX 5.0.0 for macOS Tahoe 26 on both Intel and Apple silicon, with legacy builds going back to OS X 10.2.

There is one important rule: you must download the build that matches your exact macOS version, and you should never run an older-OS build on a newer system.

Pros & Cons

Pricing

OnyX is free, distributed as donationware with an optional donation to support development. There is no paid tier, no upsell, and no subscription, which makes it the best free power-user tool on this list.

8. Disk Doctor

Disk Doctor from FIPLAB is the cheapest paid option here and the simplest to use. It is a focused junk and cache cleaner sold through the Mac App Store, which means it has passed Apple's review process before reaching you.

When we ran it, Disk Doctor walked through the common space wasters one category at a time and prompts you to make a Time Machine backup before deleting anything irreversible. It will not optimize your Mac or hunt malware, but for a few dollars it does the core cleanup job cleanly.

Key Features

Disk Doctor removes app caches, logs, and browser data, clears mail downloads and the Trash, finds large files over 100MB, cleans partial downloads and developer or Xcode files, removes old iOS software updates, and prompts for a Time Machine backup before deleting. From developer FIPLAB Ltd, it requires macOS 10.13 or later.

Because it is sold through the Mac App Store, it is sandboxed and has cleared Apple's review, though the App Store currently shows it does not have enough ratings to display an overview.

Pros & Cons

Pricing

Disk Doctor is $2.99 one-time on the Mac App Store, with no subscription. It is the easiest tool here to justify buying, since the price is roughly that of a coffee and it does its narrow job well.

Quick Comparison: Best Mac Cleaners at a Glance

How We Tested the Best Mac Cleaner Software

Our scoring weighed four things: how much disk space a cleaner safely freed up, how clearly it explained what it was about to delete, how it priced its free and paid tiers, and whether the developer is transparent about safety. We treated any tool that wanted to remove system files without warning as a red flag, and we favored apps that prompt for a backup before deleting anything irreversible.

How to Choose the Best Mac Cleaner

The right cleaner depends on what you want to fix. If your goal is to free up disk space with the least effort, an all-in-one like CleanMyMac or a simple cleaner like Disk Doctor gets you there fastest. If you mainly want to understand where your space went, a visualizer like DaisyDisk is the better tool.

Look first at transparency. A good cleaner tells you what it is about to delete and lets you review the list before it acts, rather than removing files silently. We also weigh whether the developer is open about safety, ideally with a notarized or App Store build, and whether the app prompts for a backup before any irreversible deletion.

If you mainly want to strip out app leftovers, a dedicated uninstaller, or the free AppCleaner utility, does that one job thoroughly. Finally, weigh the pricing model against how often you will use it. A one-time license like DaisyDisk or Disk Doctor suits occasional cleaning, while a subscription makes more sense for ongoing malware checks. Match the tool to your skill level, too: power users will appreciate OnyX's deep controls, while most people are better served by a guided, one-scan app.

Are Mac Cleaners Safe? (and Scams to Avoid)

Reputable Mac cleaners are safe, but the category attracts scams, so be careful about what you install. The most reliable tools in 2026 are Apple-notarized, meaning Apple has scanned them for malicious components, or distributed through the Mac App Store, where they have passed Apple's review.

When in doubt about an unfamiliar app, a quick search of the r/mac community on Reddit usually surfaces whether other users trust it. The apps to avoid are the ones that fake a problem to sell you a fix. If a "cleaner" floods you with alarming pop-ups claiming your Mac is badly infected, demands payment before it will show results, or installs itself without your clear consent, treat it as malware rather than a tool. Genuine cleaners explain what they found and let you decide.

A safe cleaner also protects you from yourself. The best ones never touch protected system files, and the most cautious, like Disk Doctor, prompt you to make a Time Machine backup before they remove anything you cannot easily get back.

How to Clean Your Mac Manually (No Software Needed)

You do not strictly need an app to reclaim space, and macOS includes solid built-in tools. To see what is using your storage, open the Apple menu, choose System Settings, then go to General and select Storage, where macOS breaks down your usage by category and offers recommendations.

From that same screen you can empty the Trash automatically, store files in iCloud, and review large files and downloads. To remove an app, open Launchpad, press and hold its icon, and click the delete button, or drag the app from your Applications folder to the Trash. For Apple's own walkthrough, see the built-in macOS storage management guide.

The catch is app leftovers. Dragging an app to the Trash removes the app but often leaves behind caches, preference files, and support folders scattered across your system. Clearing those by hand means carefully digging through your Library folder, the error-prone work a good cleaner automates. The manual route handles the obvious junk files; a cleaner is worth it for the rest.

Frequently Asked Questions

Final Verdict

After testing more than 20 apps, CleanMyMac is the cleaner we recommend to most people: its one-scan Smart Care routine safely freed up the most space while clearly explaining every deletion. If you want a free tool, CCleaner for Mac covers everyday cleanup well, and OnyX gives power users far more control at no cost.

For specific needs, DaisyDisk is the best way to see where your space went at $9.99 one-time, Disk Doctor is the cheapest paid quick-clean at $2.99, and Drive Genius wins if drive health and repair matter more than junk removal. Match the tool to the job, favor apps that are transparent and Apple-notarized, and you will reclaim real space without risk to your Mac.
