The task of selecting the best cleaner for Mac computer is presently quite urgent throughout the Mac community. With the overall progress of Mac computers, it becomes progressively harder to maintain them in a good shape. A typical modern machine may have a 128 GB or 256 GB solid-state drive, so the new storage demanding apps (especially those related to photo functions) can critically reduce its clear space. And when the unwelcomely looking message warns you that “Your disk is almost full”, you have to take steps to put things in order.

In practice, reclaiming a free space on your hard drive involves a great number of individual cleaning operations including, for example, the tasks to clean history on Mac browser, and to delete log files, old caches, and other junk items. At this point, in order to restore your machine’s capabilities, you may need a specialized program to free up disk space on your Mac. This review represents an analysis of the 10 specialized cleaner apps, which we consider to be the most prospective at the moment, and from which you are supposed to select your best Mac cleaner. So you are welcome to get acquainted with the 10 programs that belong to the top Mac cleaner software and can become a valuable help in maintaining your Mac in a good shape.


MacFly Pro is a program designed to perform both cleaning of your disk storage and a few more maintenance procedures. A characteristic feature is that MacFly Pro does not start scanning until you command, and it gives the user time to figure out what to do with a particular item.

The cleaner consists of three main modules called Smart Assistant, CleanUp and Tools.

Each module is capable of background scanning, but, at the same time, each is specialized in a particular set of functions.

For instance, Smart Assistant is focused on your Mac’s general condition. The module notifies the user about possible and/or desirable improvements, which, in the module’s opinion, might be performed at the moment. Actually, you always have a choice: to carry out a suggested improvement or postpone it. Most of the possible improvements include removing obvious junk stuff like temporary files, unused cookies, duplicates, seldom used files (especially bigger ones), unnecessary caches and etc.

The other module called CleanUp also has a scanning capacity but its scanning engine is widely customizable. A Mac user can set various filters and filter combinations to separate individual kinds of junk or dubious files, including different sorts of leftover files, email trash, and old caches.

And the third module, Tools, is responsible for a deep scanning intended to identify not only obvious or almost obvious junks, but also dubious items, which the user may delete or leave unchanged upon a thorough consideration. Besides, this module is the best especially in complicated uninstalling cases, when you wish to delete apps on mac completely without leaving any of their remainders. All deleting procedures with MacFly Pro are absolutely secure so you are guaranteed to avoid occasional deletion of a file that you actually need.

Presently, MacFly Pro is sold with a free 7-day trial, a monthly subscription costs $4.99.


Designed by iMobile (a China-based company specialized on the content management of iOS devices, iOS data recovery and Mac utilities), MacClean is freemium app (that is, free to download yet with limited application). While it is free to scan your Mac (and learn how much data can be deleted), you have to pay for performing the cleaning procedure itself (a lifetime license for $7.99). The app’s declared purpose is keeping your Mac clean and safe from malware. To the program’s advantages belong the clear and user-friendly interface, free diagnosis tool, and the built-in antivirus. However, there are also a few shortcomings such as slow and hidden customer service and the slow security scan.

On launching the program, you get to a simple and easy UI, showing you a list of functions. There are two main modules (Cleanup and Utilities), where you can select functions to optimize your machine’s performance. A nice feature is the ability to scan web browsers for malicious cookies. The cleaner app analyzes the programs’ histories and other documents and generates warnings of potential threats.

The cleaning process is easy but not very fast. Automation is weaker than on most competitor cleaners. Much is done manually. You can scan for specific files (one by one), which may be, for example, internet junk items or malicious cookies. Alternatively, you can scan for individual security issues. Then MacClean displays the files that it has flagged as junk and you decide what to do with them.

Since the program’s inception in 2015, its developers have introduced a few helpful optimization novelties such as iPhoto clean, extension manager, and binary junk data remover.

A curious feature is a quarantine. After security check, infected files are stored in the quarantine so the user can either remove or clean them. Unfortunately, the app’s consumer service is rather slow.


The DaisyDisk cleaner uses a free and open-source coding. The app mainly focuses on the disk space analyzing. The program’s name is related to its color-coded sunburst diagram resembling the plant’s petals. A single license key can download the software on the unlimited number of personal Macs. However, for commercial use, you need a purchase for each Mac. The current version requires OS X Yosemite or later, though licenses are still available for Macs running earlier versions. The program functions as a disk space analyzer. DaisyDisk features a user-friendly interface that allows visualization of your hard drive. The program’s analytical abilities allow you to quickly find items occupying the most storage on your machine.

Among the app’s advantages are a convenient algorithm for identifying and removing large unused files, fast scanning speed, and the possibility of scanning multiple disks at the same high speed. Simple shortcuts and a simple drag-and-drop technique are also worth mentioning.

However, the DaisyDisk’s single functionality may bother those who are used to all-in-all solutions on their Macs. Besides, the app lacks display of a few key file elements including date created and date last viewed. Among other shortcomings, one should mention a complex multi-step procedure of file removal and the program’s inability to preserve scanned disk information so the user has to rescan every time.

You can purchase DaisyDisk from iTunes store, Mac App Store, or from its own website for $9.99.


Designed by IObit, the MacBooster is definitely not for everyone, and many Mac users prefer macOS system utilities or other free programs that provide many similar functions. However, for new Mac users who are not yet familiar with all Mac technical peculiarities, the all-in-one MacBooster may be a decent solution. Another preference may be the app’s ability to save time keeping Mac in a good shape.

Furthermore, among the program’s advantages are the ability to reclaim considerable disk space compared to its competitors, a bunch of helpful maintenance tools, and a remarkable ease of use with a sleek and user-friendly interface.

In general terms, MacBooster is a multi-functional program providing an entire collection of helpful utilities for your Mac’s maintenance including releasing disk space and preserving the system’s security.

Besides, the app can remove malware and viruses and boost your system’s speed.

As additional pros, users mention the program’s ability to provide real-time protection and securely clean such types of privacy files as cookies, browser histories, and app traces.

As for pricing, MacBooster can be purchased for the one-time price starting at $39.95.


Dr. Cleaner focuses on memory optimization on your Mac. The program can clear your machine’s hard disk, monitor the system and assist you in uninstalling unneeded apps. Dr.Cleaner’s abilities include such basic features of a cleaner program as dealing with big files and cleaning junk items including duplicates.

Apart from the above-mentioned core features, Dr.Cleaner is distinguished for having an especially well-polished and fluid interface, for the availability of the core features in the free version, and the presentation of folders contents in the form of pie charts providing a convenient visualization. An undoubtful advantage is that Dr.Cleaner is an undemanding program and occupies a very little space on the hard disk.

Dr.Cleaner’s Pro version can also locate duplicate file copies and assist the user in managing installed apps.

However, there are a few shortcomings as well. Among them are the complex multi-stage procedure to access the main application and a somewhat indiscriminate grouping of “big files” (the corresponding group includes files from 10 to 500 MBs of size). Besides, the disadvantages include the poor selection of tools (free package) and the fact that Unarchiver and Antivirus features are only available as standalone apps.

Dr. Cleaner is distributed via free download at iTunes App Store. The Pro version costs $14.99.


CCleaner is a famous software, probably the best-known PC and registry cleaner. The program was designed by Piriform, which is a world leader in PC optimization. The program’s competitiveness is contributed by a 14-day free trial and a low price.

Compared to other similar programs, CCleaner is characterized by a shortage of features. However, this is simply because the developer also offers separate dedicated apps for deleted files recovery, disk defragmentation, and hardware analysis (Recuva, Defraggler, and Speccy respectively). But even with its limited functionality, CCleaner is able to considerably boost your Mac’s performance (in particular, by deleting junk items and correcting the registry), and customize the client settings.

Prior to repair operations, CCleaner performs an in-depth analysis of your files, disk, and registry. During that analysis, it finds a wide variety of issues that should be fixed, which usually involves deleting various kinds of junk items. The user is asked to confirm the cleaning procedure. Also, the program provides an uninstaller to delete leftovers and can select startup applications. In addition, CCleaner can manage your browser’s plugins, deal with duplicate files and perform a few more operations.

As regards pricing, probably the most attractive offer is CCleaner Professional for $24.85. CCleaner has a free version with the unlimited usage (though many functions are limited to the free option).


The OnyX Mac Cleaner is a widely known app that has been Mac users’ assistant since Jaguar (OS 10.2 X).

The utility software offering a comprehensive maintenance toolkit for your Mac. The multipurpose version of the cleaner program for OS X excels in streamlining. In particular, you can efficiently use it to verify your startup disk, configure parameters in Finder, Dock, Safari, and perform various cleaning tasks.

The program is best suited for experienced and demanding Mac users who are well acquainted with macOS. One can say that the OnyX Mac Cleaner strongly focuses on advanced functionality at the expense of interface convenience and appearance. But such a shortcoming is quite excusable for a completely free program.

The main advantages (aside from being a freeware) include the availability of tools for database rebuilding, manual system scripting and a wide variety of cleaning functions. The program contains quite a few helpful additional utilities like Screen Sharing and network diagnostics, generates explicit warning prior to advanced actions, logs all operations, and requires no registration.

As to the program’s minuses, it is not so easy to assimilate and has a mixed quality interface.


The program is a narrowly specialized cleaner with a strong focus on the perfect app uninstallation. Unlike other similar software, the AppCleaner has relatively weak means to detect malware, obsolete apps and many types of junk. Instead, it concentrates on a high quality and secure uninstalling. And the AppCleaner really excels in performing its only main function.

The program safely uninstalls apps together with all their associated files and with no leftovers remaining on your computer. When you choose a program in the AppCleaner, you can easily locate all supporting data and delete it all in a single sweep.

The program’s advantages include high speed and a complete and secure cleaning functionality. Besides, it features the Smart Delete option to detect trashed apps data, a mechanism to avoid accidental deletion, and convenient advanced management of Widgets and Plugins. And AppCleaner is a free application.

However, apart from the limited functionality (which can hardly be considered as a real disadvantage for such an overly specialized app), AppCleaner still has an important shortcoming. It does not locate leftover files of already deleted apps, while such a function would be well in line with the program’s uninstalling feature.


The recent version of MacPaw’s program is widely positioned as a strong competitor and a catch-all utility capable of deep scanning and advanced deleting.

The program includes various scanning modes such as Smart Cleanup, System Junk, iPhoto Junk, Trash Bins, Mail Attachments, iTunes Junk, and Large & Old Files, which represent sophisticated specialized cleaning utilities.

All the above modes (or tests) are widely customizable and configurable to reflect the user’s preferences.

The recent CleanMyMac 3 version adds a few more features including new scans and tests that allow advanced functionality such as detailed information about the hard drives status or the scheduler.

An important novelty in the latest version is a brief explanation for each test, which clarifies what exactly the app is about to do. The feature surely makes sense, especially for casual and new users in dealing with the program’s extended settings and preferences.

CleanMyMac 3 costs $40 for new users and $20 for upgrade users.


The program belongs to the sub-class of disk space analyzers for OS X. The Disk Inventory X is characterized by a neat organization and a considerable information volume and at the same time is free. Already on startup, the app provides a basic overview of your disks. A characteristic feature is a clickable color-coded data map on your disk, which can be a source of additional specific information. It is important that the app allows viewing the entire disk by order of file and folder size. The program’s work algorithm is quite simple yet informative. On choosing a disk for analysis, The Disk Inventory X processes its contents and then generates you a color-coded data map on which you can perform a variety of actions. In addition to the map, the user can work with a text-based list, so either form of data interpretation can be chosen depending on user’s preferences.
