CleanMyMac 3 is the latest version of the cleanup app by MacPaw. This app is very easy to use and works effectively to clean the Mac. You will particularly find it useful if you have a Mac that has been in use for a while. Over time, Macs tend to accumulate lots of junk that is not necessary. These include service copies of iPhoto images, language support files, developer files and many more. Any junk that is taking up disk space unnecessarily will be removed by CleanMyMac.

Other than being a cleanup app, this application also offers important maintenance utilities. It comes with an uninstaller, shredder and many more. The functions of CleanMyMac can be done using other apps and even the Mac’s terminal but this requires some level of expertise and time. It is best left to power users. If you are not one of these the best solution you have is CleanMyMac 3. In this CleanMyMac 3 review you will find all the details you need to decide if this is an app you need.

CleanMyMac 3 Review: Features


Smart Cleanup

The smart cleanup feature has been improved to make it more critical and efficient. Thanks to the extended intelligent safety database, the app will be able to make appropriate decisions on the material to be deleted while leaving what matters to you and the functioning of the Mac. When you select the smart cleanup feature, the Mac will be scanned for files that can be removed. Choose to clean these and the Mac will be cleaned thoroughly.


System Junk

No matter what OS it is that you are using, over time system files accumulate even those that are unnecessary. CleanMyMac 3 will get rid of any system logs, language files and cache files. Automatically saved document versions, Xcode junk and old versions of applications will be cleaned as well. These temporary files do not normally go away when the final copy is saved but with this cleaning app they will be deleted.


Mail Attachments

There is a mail attachment module that will scan for downloaded mail attachments and clean them up. When these are cleaned you will still be able to access them from your mail.


iTunes Junk

iTunes does not just store the music but other iOS data as well. The iTunes junk feature cleans all the iTunes junk you may not even be aware of. Any old device backups, software updates, copies of iOS applications and incomplete iTunes download files will be deleted.



The CleanMyMac 3 dashboard will tell users of how the system resources like memory, CPU and storage are being utilized. You will also be able to tell the health status of the battery and receive notifications on any issue the Mac may be ailing from. You will be able to clean up the RAM straight from the dashboard and improve the performance of the Mac instantly.


CleanMyMac 3 Menu

This new feature will make it possible to acess the application’s main tools without opening the CleanMyMac app. To set the menu feature go to CleanMyMac 3 then Preferences then enable the CleanMyMac menu. With the menu you will be able to monitor the trash bin, free up RAM and force quit unresponsive applications.



This feature does the work of Apple’s Disk Utility in an easy and simple way. With it you will be able to verify the startup disk, set up disk permissions and other disk maintenance functions.



CleanMyMac 3 will be able to clean up all the data that if someone gets access to they will gain private information. These include browsing history, cookies, saved passwords, message history and attachments, auto-fill values and download history among others.



macOS allows users to uninstall applications but more often than not pieces of the applications are still left within the Mac. The most common are preferences and caches. With CleanMyMac 3 when an app is uninstalled all the files associated with it are removed leaving lots of hard drive space.



There are extensions, widgets and plugins in different applications. CleanMyMac 3 brings all these in one place and gives users the option of disabling as many as they want. You can also be able to manage start up items.



This feature deletes items permanently so they cannot be recovered. Be sure not to shred any files you may wish to recover soon. Unlike placing items in trash where they are still occupying the hard drive, shredded data is lost and does not occupy any hard drive space.

Is CleanMyMac 3 Safe?

MacPaw claims that the Safety Database they have come up with contains a list of rules that determine what items need to be left in the Mac and those that need to be cleaned. They claim that with this application one will be able to clean up only files that are not useful to the user or can be obtained in a different manner. System files and user files are left intact even after a system cleanup. The pp does not affect the normal operation of the operating system in place. It only makes it load faster. The CleanMyMac application does not contain any malware or virus.
