On June 3, 2019, the inevitable happened, and Apple's Mac lovers finally saw the newly-rolled out MacOS Catalina.

OnyX is a multifunction utility that you can use to verify the structure of the system files, to run miscellaneous maintenance and cleaning tasks, to configure parameters in the Finder, Dock, Safari, and some Apple applications, to delete caches, to remove certain problematic folders and files, to rebuild various databases and indexes, and more. Then you will have to verify that you have enough available space on your hard drive. To install macOS Catalina you will need at least 12.5 Gb free, and 18.5 Gb if you will update a Mac that still uses OS X Yosemite or some previous OS. Checking if you have the necessary memory is very similar to checking the model of your Mac. OmniGroup makes some of the Mac's best productivity apps, but it also makes one of the best disk cleanup apps, too.

4. Onyx

OnyX is a french Mac cleaning solution developed by Titanium software. It weighs only 5 MB but that doesn’t mean its capabilities are limited. OnyX is a tool that programmers will have a lot of fun with. With it, you can peek under the hood of your macOS and automate a whole list of jobs, like disk cleanup and cache removal. You can even tweak the color of folders on your Mac, and even make them invisible. Deservedly, it's among the best free Mac cleaners.

OnyX is one of the best Mac cleaners because it cleans many specific under-the-surface files, like inner databases and logs. If you know what is XPC cache is, you’ll probably like this app. But for us, ordinary Mac users who came here for the design and glossy buttons, OnyX will require some learning time.
Those who use OnyX say it is stable and reliable. There is no dedicated customer service (because OnyX is free software), but you shouldn’t be worried. The only likely damage is you accidentally deleting files by yourself.

After feeding the apps to AppCleaner, you should visit the Leftovers section of the app to erase their remains. Why we place AppCleaner & Uninstaller among free Mac cleaner tools? Because it is 100% free. Whether you will fully clean your Mac using it, is a different question.

7. Smart Mac Care

If you launch Smart Mac Care, it will look hauntingly familiar to other free Mac cleaner apps. Not only features will be called the same, everything up to the fonts, will be identical to some other app you’ve just used. That’s not a minus, though. You can still free up a lot of space with Smart Mac Care.

Smart Mac Care operates by a logic of “scans.” There is a Junk Scan, Malware Scan, Privacy Scan, etc. Just like Mac Booster, Smart Mac Care removes duplicates scattered in various locations on your Mac. There’s also a Memory Optimizer feature that promises to free up RAM on your Mac. In a word, Smart Mac Care resembles every other generic product whose only difference is in packaging. This is supported by the fact that we couldn’t find any credible third-party reviews for this app.

On another skeptical note: to uninstall Smart Mac Care you have to enter your admin password. This is not the case with other Mac cleaners we’ve used.
