Nothing is more frustrating than wanting to download a movie so you can watch it later, or your office files so you can complete that work at home, only to find out your memory storage is full. Unfortunately, this probably happens more often than you would like.

Additionally, insufficient memory causes your device to act up and malfunction. That is when your screen starts to freeze, it gets longer to open an app, not to mention the annoying frequent pop-up notification of “storage full/ full memory”.

Fortunately, these problems can be easily solved with Mac memory cleaners that free up RAM.

What is RAM

RAM stands for Random Access Memory, which means your computer must be able to process, store, and access data quickly for your apps, software, and programs to work efficiently. Simply put, it is a short-term memory that stores the processor’s current data.

RAM is like a temporary memory bank that stores any data that your computer needs to access quickly. While all computing devices store data for longer-term access (on Cloud, SSD, Hard Disks, etc.), they need RAM to process, store, and access information you are currently working on.

What is Unified Memory

With Apple producing its own processors, the M1, and M2 chips, RAM would soon be removed from any Apple device using these processors, which is essentially all future iterations of the Macbook. This is because the company now uses Unified Memory, which is a part of the device. This means no more portals for RAM on the motherboard.

Simply put, a unified memory is like an upgraded version of RAM. It not only processes and stores data that you need to access fast, temporarily but also for a longer period of time. While RAM can only access the CPU or GPU, one at a time, a unified memory can access both of these at the same time.

It does all the work of RAM only that RAM is temporary and Unified Memory is persistent and much faster. This means that with the latter, you can access different apps, software, programs, and other content simultaneously, while with the former, you can’t.

The downside is that this cannot compare to SSD and memory storage. As much as it processes and stores data faster and longer than RAM, keep in mind that it doesn’t store data permanently.

Also, unlike RAM, you cannot upgrade a Unified Memory. So if you go for these models you will also need to ensure you get enough memory, which is why your new or old Mac needs a memory cleaner app.

Why does the memory (RAM) get full

There could be a ton of reasons why your memory continues to max out, so it is important to identify the specific cause so that this issue can be fixed.

  • You have multiple apps running at the same time

It is a common habit to let multiple apps run at the same time. This means you are accumulating more and more apps in the background, which is taking up more and more space. Your system will run out of application memory, and when this happens, more problems can occur.

  • You have multiple apps running in the background

What if you are not running multiple apps and software at the same time, but you are still getting memory problems?

There could be apps running in the background without your knowledge. So technically, you are still running too many programs. To stop this, you can just ‘quit’ or ‘force quit’ these apps.

  • Too many browser extensions

Browser extensions make work easy, but excessive extensions on your browser could be the root cause of your memory problems because as soon as you open your browser, you activate these extensions and plugins too. While they are all running at the same time, they are taking up more space.

If this is your issue, it is time to declutter, sort out, and delete the ones you rarely or never use at all. You may also want to deactivate or turn off some extensions that you don’t need when running your browser.

How to clear memory and reduce RAM usage on Mac

If you use up your RAM, chances are your Mac will start to slow down. To speed it up, you need to free up memory and reduce RAM usage.

Restart your device

Your problem could be easily solved by something as simple as restarting your device. You have probably even had your own device prompt you to restart or shut down your Mac and then turn it back on.

When you restart your Mac, the system empties RAM and other disc cash. That is why in most cases when you turn it back on or restart it, you find it to be running more smoothly.

The only time this is not a great option is when your system freezes up and hung, and you don’t want to lose some information and data you are working on.

Check Activity Monitor

Activity monitor is the Windows Version of Task Manager. It displays your memory usage and shows you apps that are using up more space than they should.

Select the memory tab to see the detailed graph of each process and how much memory it is taking up. Details of Memory Pressure, Swap Used, Memory Used, and Cached files are displayed here. You can then find out the processes and apps hogging RAM and take the necessary steps.

Check your apps

You may want to delete some apps that you no longer need and use or close apps and programs running in the background. The point is to get rid of unnecessary apps and programs hogging your RAM.

Top apps to free up memory/RAM on a Mac

Quitting or Force quitting an app doesn’t always solve your ‘Memory Full’ problems. That is where memory cleaners come in. These are apps and software that clean out unnecessary junk from your device and give you an easy time working on your computer.
