Are you running into constant crashes and freezes and losing important work? Or are you experiencing lag when you are trying to run any application? If you are reading this article, chances are you are running into memory issues. Look no further as this is the article for you. The purpose of this article is to empower you, as a dedicated MacOS user to confidently and safely optimize your device performance by cleaning your device memory. First, we will inform you of the concepts of memory cleaning, and then introduce you to the latest software and tips available.

Random Access Memory or RAM is a temporary storage where processes are kept until your Mac is turned on. This allows you to quickly open up software and files during your operation. However, these processes take up RAM space. Moreover, for many different reasons RAM space is shortened which slows down your PC speed and performance. Which is where Mac memory cleaners come in. They can automate the memory management process; thus your Mac’s RAM is used in the most effective way. They can allocate and deallocate RAM space, freeing up precious memory resources, saving you from memory hogging and leaking – thus making your life easier.

In this article, we will look at how to use the built-in Activity Monitor in Mac, how to find the best memory cleaner application for Mac and then discuss the 5 best Mac memory cleaners available in the market today. These are:

  • Macube
  • CleanMyMac X
  • MacCleaner Pro by Nektony
  • MacKeeper
  • Parallels Toolbox

Part 1: Exploring Memory Cleaning for Mac

If your system is responding very slowly and you are experiencing lags and crashes, it is likely that applications and software in the background are behind the memory hogging. As an initial step, you should close applications from the menu bar, and close all the unused tabs in your browser.

Then, you can open the Force quit application manager. Press the keyboard shortcut Command + Option + Esc. Here you can forcibly quit some applications that are running in the background.

However, for a more detailed look at all the process running in your MacOS, you can utilize the Activity Monitor built-in your iMac, Macbook Pro and Air devices. This will allow you to see all the processes and applications that are running in your system, which you can force stop if you require it so. Just follow these steps:

Step 1: From Finder, Go to Applications folder > Utilities > Activity Monitor App

Alternatively, you can search it in Spotlight Search. You will recognize it by the icon.

Step 2: In the window, you can see 5 tabs: CPU, Memory, Energy, Disk and Network. For our requirements, only CPU and Memory are important.

Step 3: The window shows you a list of activities running currently in your Mac. At the bottom, you can see more detailed report on the amount of CPU load used by the System and the user end respectively.

To quit the desired process, select it and then press the x symbol on top. Then click Quit or Force Quit.

Step 4: Similarly, in the Memory tab, you can inspect the amount of RAM or memory any process is using. At the bottom, a more detailed view can be seen of the breakdown of physical memory capacity and the amount currently being used.  As you can see, MacOS automatically compresses some memory to free up more RAM to use. Thus, MacOS performs some memory management of its own.

In the list view, you can see the list of applications sorted according to memory usage as seen on the Memory column. To quit the desired process, select it and then press the x symbol on top. Then click Quit or Force Quit.

Activity Monitor is a useful tool for monitoring your applications’ resource usage and performing some memory management yourself. However, it gets tricky when you have multiple applications, hidden memory usage (such as applications that have not cleared up the RAM after closing causing memory leaks) and malware. Furthermore, you may not be feeling comfortable closing applications without properly monitoring them as they may be important system processes. Then you may need the assistance of a Mac memory cleaner.

Part 2: Choosing the Right Memory Cleaner

In the previous section, we saw how to use the Activity Monitor to track applications’ RAM usage and how to perform some basic memory cleaning ourselves. However, you can exponentially make this process easier and faster by using dedicated Mac memory cleaning tools. Here are some of the ways a Memory Cleaner software can benefit you:

  • Helps you multitask easier and smoother with less freezes, lag and crashes.
  • Improves speed, responsiveness and load time of process and applications.
  • Manages resource allocation efficiently by sorting out fragmented RAM resources and removing the need to swap (i.e switch to physical memory usage).
  • Alleviates the pressure on memory capacity.

Now that you understand how important a RAM cleaner software for Mac is, it is compulsory to know how to choose the best memory management application for this purpose. There is a plethora of great memory cleaners for MacOS available in the market. So, look out for these qualities before making that purchase:

  • Compatibility: First and foremost, the application must be compatible with your version of MacOS and should be constantly kept up-to-date.
  • Performance: The ideal Mac memory cleaner should be efficient and have little impact on your system’s performance so that it does not freeze your system while cleaning.
  • Features: RAM cleaners and memory management software should have all the comprehensive set of features and functionalities that can help you perform complete memory management, such as one-click RAM cleanup, activity monitoring, memory leak notifications, speed boosting and device health checkup, to name a few.
  • Price: Last but not least, the ideal software should also fit your budget.
