Like any computer equipment, MacBook and iMac become clogged and require maintenance over time. Usually, macOS handles this task on its own, but in some cases, it requires user control and forced cleanup provided by a high-end Mac cleaner.

The latest Mac models are equipped with relatively small capacity solid-state drives. As a result, users quickly discover that the disk is full of various data and files. Even a very modest iTunes or iPhoto library can fill almost the entire drive of a couple of hundred gigabytes. To solve the problem with available memory in macOS, you can turn to external applications.
The most considerable “eaters” of hard disk space are files and folders that users have forgotten about, or that have extended without their knowledge, like folders with iPhone and iPad backups. Many will agree that working on a clogged computer is a living hell. However, using specialized utilities, you will be reminded once again of the days when your MacBook or iMac was brand new and clean in all respects.
Top 4 Free Mac Cleaners
Before you start using any of the applications mentioned below, it is highly recommended that you create a backup copy with the help of the Time Machine function.
Onyx is a powerful tool for system tuning with a vast number of functions for optimizing, configuring, and cleaning macOS. This entirely free cleaner doesn’t have the same user-friendly interface as the well-known CleanMyMac, but the features of both utilities are similar in many ways.
In the “Maintenance” section of this program, you can delete the system and application cache, logs, and empty the trash, check the structure of system files, and run maintenance scripts. Besides, the “Options” section contains a host of features for fine-tuning Finder, Dock, and other aspects of the system that are not available in macOS by default.
The disadvantages of Onyx include high complexity for the average user. There is a possibility that the system files may be damaged by ignorance or error, which may cause malfunctions.
GrandPerspective graphically shows the state of the Mac file system. When you launch the utility, you will be offered to select the desired folder for scanning. Once you figure out which folders and files take up too much space, you may effortlessly determine the ones you don’t need and delete them, freeing up as much space as possible with minimal effort.
Scanning 14 GB of disk space occupied by files with GrandPerspective takes approximately one minute. What can be somewhat inconvenient in this cleaner is the need to click on the squares or hover the cursor over them to find out what kind of file is hidden behind them. Otherwise, this tool does its job perfectly.
The undoubted advantage of this utility is the availability of a free version with minimal functionality. If there is a need for additional features, the user is offered two options at once. In general, CCleaner has excellent capabilities in cleaning the system and optimizing the operation of your MacBook and iMac. This program is in high demand among computer owners all over the world. There are also versions for PC and mobile devices running on Android.
Disk Inventory X
The task of Disk Inventory X is to graphically visualize the contents of the hard disk to find problem areas quickly. When you launch this Mac cleaner, you are prompted to select the media to analyze. Both internal and external disks (Time Capsule, USB sticks, etc.) will be displayed here. After that, content processing will begin, which will take from one to five minutes, depending on the disk size. When you finish, you will see a directory tree on the left, and a visual representation of information according to data types on the right.
Now you need to select the largest files in the list, make sure that they are unnecessary, and remove them. Do not worry; Disk Inventory X will not allow you to delete the folders that the system needs and that require administrative access rights to them.
There are other ways to clean your Mac, including expensive utilities. However, the programs mentioned above will be enough to support the fast operation of your MacBook and iMac.
