Memory Cleaner


Monitor memory usage

Memory Cleaner is an application that helps you free up unused RAM and speed up your Mac. Once you launch the app, it regularly scans your system and shows the memory usage on your Mac, including the memory used by a single application launched on your system.

Launch Memory Cleaner and find the memory indicator in the menu bar. Click the Memory Cleaner’s icon to see the RAM monitor – the amount of free RAM, the size of the RAM being used, and the amount of memory occupied by active applications. General memory usage is displayed both by percentage and in GB.  Memory cleaner window showing the memory usage


Free up memory

Memory Cleaner allows you to clean up your RAM memory, which in reality is free. However, the system shows it as occupied by apps. Just check the indicator periodically. If the amount of used memory reaches its peak point, click “Cleanup”. After the cleaning process you will see the amount of cleared memory in the window and the time of the last cleanup.

If you have freed enough memory, then go on with your work. Sometimes all of your RAM may be used for active processes and it is impossible to clear enough memory. In that case, close unused applications and then click Cleanup once more. By performing these two simple steps, your Mac will always have to operate at high speed.


Automatic cleanup mode

Memory Cleaner allows you to set up an automatic cleaning of your inactive memory. You can change the settings right in the Memory Cleaner window.

  1. Click the Memory Cleaner icon in the menu bar.
  2. Switch on the option “Automatically free up”. Memory Cleaner window with the automatic cleanup option highlighted

Disk usage

Besides monitoring your RAM usage, Memory Cleaner provides an additional feature called Disk Usage. It helps you monitor your disk space usage and free up space on your Mac.

In the Disk Usage section of the Memory Cleaner window, you can see the volume of junk files, duplicate files, applications, and large and old files. You can click on each category of files to see them in more detail and manually find and remove those unneeded files.

Also, Memory Cleaner synchronizes with other Nektony applications of MacCleaner Pro’s bundle. With these additional tools, you can quickly and easily remove all junk files, like caches, logs, Mail attachments, duplicate files, large and unnecessary files, and apps with their remaining files. As a result, you can recover valuable disk space and speed up your system. Simply switch between the tabs in the Disk Usage section and click the appropriate buttons to open MacCleaner Pro or additional tools from its bundle.
