The capacity to multitask is one of the advantages computers have had over you and me. That and their speed in execution of tasks. With brands such as Mac, they can completely revolutionize your lifestyle in every aspect. From work to leisure, computers have been seen to make a difference.

However, technology should not be fully trusted. Systems fail, and the Mac is no exception. One sign of failure is when your system runs out of application memory and you have to make more free space. But why? Well, when you have a tone of apps installed with many of them running simultaneously, your Mac is likely to get worked up.

When you are done reading the article, you’ll have great insight into what happens to your MacBook’s memory. Here we go!

Part 1. What is Mac Application Memory

Mac Application Memory is the part of your system that is designed to handle running applications. Usually, when you download and install a software, it gets placed on your internal Hard Drive. It is what is commonly called the disk space. It is also where you keep your other files for storage.

However, a time comes when you need to launch the application. When it’s up and running, all its operations take place in the RAM (Random Access Memory), also known as the application memory in Mac.

So, how do these applications work with the application Memory?

When an application is running, its files with code (in various languages), are constantly availed to your CPU for processing. That is why it is termed as ‘random.’

Therefore, when your RAM is working optimally, there are no delays. Applications launch faster, and games play seamlessly without constant freezing. Yes, freezing. If you are a gamer, you must have at one point witnessed this.

Also, the application memory works hand in hand with your CPU. As mentioned above, the CPU does all the logical processing, but if slow, you can’t feel the power of your application memory. Your system will still seem slow even though you may not have run out of application memory.

But what does it mean to ‘run out of application memory’? Is it just because of the many apps you have open or is there more to it?

You will get all the answers in the next part.


Part 2. What "Mac Run Out of Application Memory" Means

what happens when it runs out? Well, just like we get frustrated and confused when we think about too many issues or try to solve multiple problems with our minds, so does the Mac system.

Some of the causes include:

  1. Excess multitasking of the system: Your Mac application memory can run out because of excess multitasking imposed on it beyond its capacity. In today’s technological advancements, it doesn’t take heavy apps such as Adobe premiere or graphically intense games to clog your application memory. Even browsers can tremendously impact your RAM.
  2. The current demanding browsers: Take a look at the Chrome browser. How does it work? Every free browser is equivalent to a running process in the application memory. Thus, multiple open browsers behave or are like separate apps.
  3. Running other apps: Furthermore, we all work on our Macs while listening to music in the background. So, when you put all this together, you realize that your system loads page slower even though you have high-speed internet. And it gets worse.
  4. Browser enhancements: Websites now have ads and pop-up videos. Since you also need a seamless browsing experience, you install extensions on your browsers and allow plugins flash and scripts from websites. You also want instant access to your work, so applications once opened are left running in the background.
  5. A full Hard Drive: As if all this is not enough, more and more content gets downloaded until your hard drive gets full. But what does that have to do with the application memory running out? Well, while running, your Mac OS regularly makes use of a ‘virtual memory’ created on your hard drive. The virtual memory works as RAM if the application memory gets overwhelmed. When full, there is no room for expansion, and thus your Mac runs out of application memory.

Also, applications can crash as a result of your Mac running out of application memory. It is because the CPU can no longer access their files. It can be dangerous for you if you are doing sensitive work as your progress can easily get lost. In extreme cases, your Mac OS can malfunction.

When it comes to turning on the camera on your Mac, there is no on and off switch. Neither is there a software dedicated to operating the camera.

Therefore, how can you check on your application memory?


Part 3. How to Check the Application Memory on Mac

You need to continually keep tabs on your Mac application memory to keep it from running out. It ensures you don’t launch unnecessary apps. Also, it prevents you from downloading and installing more apps that you may not need.

Thus, checking of your application memory goes hand in hand with monitoring of disk usage. As explained in the previous part, it is also a culprit in leading to your Mac running out of application memory.

So, how do you check your application memory on Mac?

  1. Go to the Apple logo at the top left and click on it.
  2. Select ‘About This Mac.’
  3. On the window that opens, go to the ‘Overview’ tab. Here various details of your Mac are shown, including Memory usage.

You can also make use of the Activity monitor that shows real-time memory usage. It is also considered as Apple’s Task manager. Its location is in the /Applications/Utilities/folder.

To launch it using the Spotlight search field:

  1. Simultaneously press Command + Spacebar.
  2. On the search window type ‘Activity Monitor.’
  3. Select it when it comes up to launch the app.

3. Create space on your Hard Drive

To create space on your Hard drive means some of your files need deletion which can be either by deleting or backing up to your computer or an external Hard Disk.

To check on your storage:

  1. On the Apple icon, select About this Mac.
  2. On the window that opens, click on the storage tab.

A bar showing usage of your internal drive appears. You can then begin deleting files.

4. Remove unnecessary browser extensions

Whether on Chrome or Safari, find their extensions menu and remove unnecessary one. These extensions contribute significantly to your Mac memory running out as they mostly work in the background.

5. Open fewer windows.

Whatever it is you are working on, ensure your screen is clear of windows you don’t check on. Closing unnecessary apps speed up your system. For apps such as browsers, sites can easily be bookmarked so as not to lose them. Other applications can have their work saved.


Part 5. Use Recoverit to Recover Disk Data

During the process of clearing your system, it is possible to accidentally delete applications that were otherwise useful but mostly worked in the background, e.g., screen brightness controllers. You can also end up deleting system files amongst other essential data in your system.

In such a situation, how do you get back the files, mainly when you already emptied the Trashcan?

Well, there’s a savior! It is called Recoverit Data Recovery Mac with the capacity to safely recover deleted files of all formats.
