You still remember the first thing on your mind when you were buying your new MacBook that this Machine will always keep up with your pace and will never slow down on you. That’s exactly what these awesome machines are built to do. But sooner than you think, it starts slowing down. The first thing you need to know is that the performance of your Mac depends a lot on the memory usage on the device. We will talk about some of the ways to learn how to reduce memory usage on Mac and get it to maximum performance again.
Check Your Available Memory Usage on Mac First!
All the applications developed for use on Apple Machines are built to optimally use the memory available. But memory management for MacBook becomes critical when you open too many applications that are running simultaneously. This results in major memory overload.
Once you experience your Mac slowing down, you should start analyzing the memory usage. If you don’t know how to check memory usage on Mac, the best application to start with is the Activity Monitor. You can easily find this application in the Utilities or you can simply type the name of the application in the Spotlight window.
Activity Monitor: Helpful Tool in Analyzing Memory Usage on Your Mac
Activity Monitor is a built-in application in MacOS which tells you everything that is running on your MacBook. It gives you a complete overview of your MacBook’s memory usage. Here you can find out what applications are currently running and how much memory is being utilized by each of the applications. It is an excellent tool in analyzing the memory usage as it gives you plenty of details on the resources being consumed by any application, including the memory being used, Number of threads utilized by each app, CPU usage, etc.
What's more, ths Activity Monitor shows how you can add different columns to check a particular resource being utilized by an application and play with the statistics to shut down what you don’t need and that eats too much of memory. To illustrate a few, let’s have a look at the memory page of Activity Monitor.
The memory page is very informative when you understand all that it is showing to you;
Memory Pressure: This graph gives you the usage of memory over a period of time. You can set the Update Frequency and set the intervals. The right-most bar is the current memory usage, going back in time as you move to the left of the graph. The color of the graph shows the usage level.
- Green – RAM Memory available.
- Yellow – RAM Memory still available, tasked by memory-management processes (like Compression)
- Red – RAM Memory completely used. This is the time where you should start shutting down some apps.
You can see the total installed RAM on your computer shown as,
Physical Memory: Total memory installed.
The part which you are really concerned about is the one marked as,
Memory Used: Total memory being used by the running apps and processes. Getting inside to have a deeper understanding of the memory distribution allows you to play with it and get the best performance.
- App Memory: Total memory used by all the apps/processes.
- Wired memory: As the name suggests, this memory is (virtually) hard-wired and you cannot make any changes to the processes using this memory. These are usually the primary processes of your Machine and they need the memory with the quickest access and cannot be swapped with the memory on disk.
- Compressed: The MacOS will compress a chunk of memory in the RAM to make more space for the utilization of other apps. You can see the column of compressed memory to see how much actual and compressed memory is used by each process or application.
Swap Used: The MacOS will utilize some space on the disk drive of your Mac. This is used to free up physical space on RAM for the applications requiring more intense use of memory.
Cached Files: The MacOS keeps the recently closed applications as cached files for quick loading once you restart the same application. However, this memory is available to be used by any new application if the same application is not started.

No matter what computer you are using, you know that your desktop is filled with unnecessary and unused icons scattered all around the screen. Don’t worry; this is what we do on all our computers. But if you want to lower the memory usage on your Mac, you might want to steer away from cluttering your desktop.

This takes up space in your RAM which you definitely want to save.
2. Manage Memory Usage in Finder
The Finder application on Mac can sometimes take up a lot of memory of your system. You are thinking that Finder should not be taking up this much space, right. It is probably because the Finder application is set to show all files available on the system. Try changing the default display of Finder to not show All My Files. This will work wonders for you.
3. Force Quit Memory-eating Processes
In the Activity Monitor, you can see which applications are consuming most of the memory. These memory-hogging processes are slowing down your system. You can select to Force Quit these processes to save memory on your Mac.
4. Delete Browser Extensions
The add-ons and extensions on the internet browser are nice tools for quick access to features you need while surfing the internet. But more often than not, they are consuming more memory than they are being helpful. You can save a lot of memory on your Mac by deleting the unwanted browser extensions.

6. Disable Login Items
The items that are set to launch on every login are going to use a lot of memory space.

Here are the simple steps to do that: Click the Apple icon > select System Preferences > Click Users & Groups > Select the login item you want to remove, then click the Remove.
Using Umate Mac Cleaner to Disable Startup Items is your one-click solution to fix this issue. Select the items you want to disable on your next login and you will start your Mac with a bunch of memory saved.
7. Purge RAM in Terminal (for Advanced Users)
Open the terminal on your Mac and enter the command ‘sudo purge’. This feature requires admin rights so you would have to enter the password here then the system will clear the inactive memory. We strongly advise against using this method unless you know your way around your Machine.
If You Use Chrome Browser, Here's Bonus Tip to Lower Memory Usage
If you are using Google applications like Gmail, Google Drive, etc. This tip might be useful on how to lower memory usage on Mac. Google Chrome makes use of the system GPU for its processes to help load web pages super fast, however, this process takes a lot of memory on your system RAM. Fortunately, there is a way to control this. Use the Task Manager of Google Chrome to manage the memory available for use by Chrome, and you are good to go!
Anyway, You Should Keep Your Eye on Mac's Memory Usage
If your Mac is boosted up with 16 gigs of RAM memory, then you might have a lot of free space to use up for unnecessary applications. But with the basic 4 or 8GB RAM machine, you would require the monitoring more often. More applications running on the Mac means more memory usage. This makes it very important that you should keep a check on your applications. Learning to read and analyze the memory page of the Activity Monitor will be extremely useful in memory management for your Mac and keep your MacBook memory usage under check.
