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:
- 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.
- 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.
- 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.
- 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.
- 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?
- Go to the Apple logo at the top left and click on it.
- Select ‘About This Mac.’
- On the window that opens, go to the ‘Overview’ tab. Here various details of your Mac are shown, including Memory usage.
- For more information, click on the ‘System report’ button.
- Under hardware, find the Memory tab. On the right pane, you will see the slot details.
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:
- Simultaneously press Command + Spacebar.
- On the search window type ‘Activity Monitor.’
- Select it when it comes up to launch the app.
You can also use another way if your spotlight doesn’t work.
- Go to the finder icon on the application dock. It is the icon with two different face colors.
- On the windows, select Applications from the side menu.
- In the applications, open the Utilities folder.
- Double click the ‘Activity Monitor’ to launch it.
For continuous monitoring, you can keep the Activity monitor pinned on your applications dock. That way, accessing it is made easy.
Part 4. Solve 'Your System Has Run out of Application Memory'
You have seen how, for various reasons, your system can efficiently run out of memory and wreak havoc on your Mac. Symptoms of your Mac running out of memory include apps taking long to launch and files taking longer to open.
Now you can check out how to solve the error ‘your system has run out of memory’ by making use of the following solutions:
1. Using an activity monitor.
Launch the Activity monitor as illustrated above and even pin it as explained to keep you up to date with what is happening on your system. From the Activity Monitor, you can check on quite many parameters of your system’s operations, including CPU usage, memory usage, disk, amongst others, as shown in the image below.
2. Uninstall irrelevant applications.
You can do so manually through the applications folder:
- Open the applications folder through the Finder icon.
- Find the icon of the program to uninstall and right click on it.
- On the drop-down menu, select Move to Trash.
- Empty your Trash.
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:
- On the Apple icon, select About this Mac.
- 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.
You must realize that you are the keeper of your Mac computer. Despite the usage, it is your responsibility to ensure it doesn’t encounter issues such as running out of memory.
Monitoring of your Mac system is a day to day activity. Checking the disk usage and memory consumption should keep you informed of its status.
Employing techniques of frequently freeing up space on your Hard Disk can go a long way in saving you time when applications run. Where the memory has been deficient, and you also need all the apps, you can upgrade.
So, the help you have found from this article, don’t forget to share it widely with the rest of the world around you.

This article describes some of the commonly used features of Activity Monitor, a kind of task manager that allows you see how apps and other processes are affecting your CPU, memory, energy, disk, and network usage.
Open Activity Monitor from the Utilities folder of your Applications folder, or use Spotlight to find it.
Overview
The processes shown in Activity Monitor can be user apps, system apps used by macOS, or invisible background processes. Use the five category tabs at the top of the Activity Monitor window to see how processes are affecting your Mac in each category.
Add or remove columns in each of these panes by choosing View > Columns from the menu bar. The View menu also allows you to choose which processes are shown in each pane:
- All Processes
- All Processes Hierarchically: Processes that belong to other processes, so you can see the parent/child relationship between them.
- My Processes: Processes owned by your macOS user account.
- System Processes: Processes owned by macOS.
- Other User Processes: Processes that aren’t owned by the root user or current user.
- Active Processes: Running processes that aren’t sleeping.
- Inactive Processes: Running processes that are sleeping.
- Windowed Processes: Processes that can create a window. These are usually apps.
- Selected Processes: Processes that you selected in the Activity Monitor window.
- Applications in the last 8 hours: Apps that were running processes in the last 8 hours.
CPU
The CPU pane shows how processes are affecting CPU (processor) activity:
Click the top of the “% CPU” column to sort by the percentage of CPU capability used by each process. This information and the information in the Energy pane can help identify processes that are affecting Mac performance, battery runtime, temperature, and fan activity.
More information is available at the bottom of the CPU pane:
- System: The percentage of CPU capability currently used by system processes, which are processes that belong to macOS.
- User: The percentage of CPU capability currently used by apps that you opened, or by the processes those apps opened.
- Idle: The percentage of CPU capability not being used.
- CPU Load: The percentage of CPU capability currently used by all System and User processes. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The color blue shows the percentage of total CPU capability currently used by user processes. The color red shows the percentage of total CPU capability currently used by system processes.
- Threads: The total number of threads used by all processes combined.
- Processes: The total number of processes currently running.
You can also see CPU or GPU usage in a separate window or in the Dock:
- To open a window showing current processor activity, choose Window > CPU Usage. To show a graph of this information in your Dock, choose View > Dock Icon > Show CPU Usage.
- To open a window showing recent processor activity, choose Window > CPU History. To show a graph of this information in your Dock, choose View > Dock Icon > Show CPU History.
- To open a window showing recent graphics processor (GPU) activity, choose Window > GPU History. Energy usage related to such activity is incorporated into the energy-impact measurements in the Energy tab of Activity Monitor.
Memory
The Memory pane shows information about how memory is being used:
More information is available at the bottom of the Memory pane:
- Memory Pressure: The Memory Pressure graph helps illustrate the availability of memory resources. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The current state of memory resources is indicated by the color at the right side of the graph:
- Green: Memory resources are available.
- Yellow: Memory resources are still available but are being tasked by memory-management processes, such as compression.
- Red: Memory resources are depleted, and macOS is using your startup drive for memory. To make more RAM available, you can quit one or more apps or install more RAM. This is the most important indicator that your Mac may need more RAM.
- Physical Memory: The amount of RAM installed in your Mac.
- Memory Used: The total amount of memory currently used by all apps and macOS processes.
- App Memory: The total amount of memory currently used by apps and their processes.
- Wired Memory: Memory that can’t be compressed or paged out to your startup drive, so it must stay in RAM. The wired memory used by a process can’t be borrowed by other processes. The amount of wired memory used by an app is determined by the app's programmer.
- Compressed: The amount of memory in RAM that is compressed to make more RAM memory available to other processes. Look in the Compressed Mem column to see the amount of memory compressed for each process.
- Swap Used: The space used on your startup drive by macOS memory management. It's normal to see some activity here. As long as memory pressure is not in the red state, macOS has memory resources available.
- Cached Files: Memory that was recently used by apps and is now available for use by other apps. For example, if you've been using Mail and then quit Mail, the RAM that Mail was using becomes part of the memory used by cached files, which then becomes available to other apps. If you open Mail again before its cached-files memory is used (overwritten) by another app, Mail opens more quickly because that memory is quickly converted back to app memory without having to load its contents from your startup drive.
For more information about memory management, refer to the Apple Developer website.
Energy
The Energy pane shows overall energy use and the energy used by each app:
Download Mac Apps
- Energy Impact: A relative measure of the current energy consumption of the app. Lower numbers are better. A triangle to the left of an app's name means that the app consists of multiple processes. Click the triangle to see details about each process.
- Avg Energy Impact: The average energy impact for the past 8 hours or since the Mac started up, whichever is shorter. Average energy impact is also shown for apps that were running during that time, but have since been quit. The names of those apps are dimmed.
- App Nap: Apps that support App Nap consume very little energy when they are open but not being used. For example, an app might nap when it's hidden behind other windows, or when it's open in a space that you aren't currently viewing.
- Preventing Sleep: Indicates whether the app is preventing your Mac from going to sleep.
More information is available at the bottom of the Energy pane:
- Energy Impact: A relative measure of the total energy used by all apps. The graph moves from right to left and updates at the intervals set in View > Update Frequency.
- Graphics Card: The type of graphics card currently used. Higher–performance cards use more energy. Macs that support automatic graphics switching save power by using integrated graphics. They switch to a higher-performance graphics chip only when an app needs it. 'Integrated' means the Mac is currently using integrated graphics. 'High Perf.' means the Mac is currently using high-performance graphics. To identify apps that are using high-performance graphics, look for apps that show 'Yes' in the Requires High Perf GPU column.
- Remaining Charge: The percentage of charge remaining on the battery of a portable Mac.
- Time Until Full: The amount of time your portable Mac must be plugged into an AC power outlet to become fully charged.
- Time on AC: The time elapsed since your portable Mac was plugged into an AC power outlet.
- Time Remaining: The estimated amount of battery time remaining on your portable Mac.
- Time on Battery: The time elapsed since your portable Mac was unplugged from AC power.
- Battery (Last 12 hours): The battery charge level of your portable Mac over the last 12 hours. The color green shows times when the Mac was getting power from a power adapter.
As energy use increases, the length of time that a Mac can operate on battery power decreases. If the battery life of your portable Mac is shorter than usual, you can use the Avg Energy Impact column to find apps that have been using the most energy recently. Quit those apps if you don't need them, or contact the developer of the app if you notice that the app's energy use remains high even when the app doesn't appear to be doing anything.
Disk
The Disk pane shows the amount of data that each process has read from your disk and written to your disk. It also shows 'reads in' and 'writes out' (IO), which is the number of times that your Mac accesses the disk to read and write data.
The information at the bottom of the Disk pane shows total disk activity across all processes. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The graph also includes a pop-up menu to switch between showing IO or data as a unit of measurement. The color blue shows either the number of reads per second or the amount of data read per second. The color red shows either the number of writes out per second or the amount of data written per second.
To show a graph of disk activity in your Dock, choose View > Dock Icon > Show Disk Activity.
Network
The Network pane shows how much data your Mac is sending or receiving over your network. Use this information to identify which processes are sending or receiving the most data.
The information at the bottom of the Network pane shows total network activity across all apps. The graph moves from right to left and updates at the intervals set in View > Update Frequency. The graph also includes a pop-up menu to switch between showing packets or data as a unit of measurement. The color blue shows either the number of packets received per second or the amount of data received per second. The color red shows either the number of packets sent per second or the amount of data sent per second.
