Common Reasons for “Your System Has Run Out of Application Memory” Issue 

When your Mac’s system runs out of application memory, it can’t deal with many active processes. Let’s take a look at some of the possible causes of the problem.

I. Too Many Apps Running

Nobody is a stranger to running multiple apps at the same time. However, having too many active apps and the ones in the background will take up more and more RAM, eventually resulting in the “Your system has run out of application memory” error. Keep an eye on the apps and quit the ones you don’t need at the moment.

II. Unneeded Browser Extensions

Some extensions can affect the performance of your browser, and it may also lead to your Mac running out of RAM, slowdowns, and the “Your system is out of application memory” message popping up on your screen. Try to minimize the number of browser extensions you use and open fewer tabs simultaneously to save memory and CPU resources.

III. macOS Monterey Bug

I. Force Quit Unneeded Applications

macOS automatically open the Force Quit dialogue window when the “Your system has run out of application memory” error occurs.

When it happens, just click on Force Quit near the application that uses most of the Mac memory.

Another way to Force Quit applications is to do it yourself using the Activity Monitor:

1. Open Finder.

2. Open the Utilities folder and choose Activity Monitor.

3. Under the Memory tab, select the application that you want to force quit, and click the Quit button.

II. Restart Your Mac

The easiest way to free up RAM and fix the problem is to restart your Mac. Restarting allows your system to shut down all system processes and clean up RAM properly. 

However, constant restarting may be annoying as it makes you quit all the processes. Besides, it might be time-consuming, especially when you have a video call in a few minutes and your Mac is lagging. 

That’s why there is another option for clearing RAM. Use the commands in Terminal:

1. Open Terminal.
2. Type sudo purge command and press Enter.
3. Enter the admin password (the one you are using when turning on the Mac) and press Enter again. 

4. Your RAM will be cleared.

III. Uninstall Browser Extensions

Browser extensions are really helpful for easy navigation. However, having too many useless or outdated extensions can lead to the “Your system has run out of application memory” message error on Mac. Deleting the ones you don’t use or need may help the situation.

Let’s find out how to remove extensions from the most used browsers— Safari and Chrome.

Uninstalling applications is another way to reduce Mac memory usage. We install Mac apps just to test and then completely forget about them, or we still keep the apps that have only been used once or twice. Often they launch once you turn on your Mac, slowing down the system. Consequently, “Your system is out of application memory” may pop up.

To update macOS to the latest version:
