“Your system has run out of application memory” is an error message encountered by some Mac users, often seemingly out of nowhere. The message appears next to the option to close applications forcibly, which if an application that consumes a large amount of resources is forcibly closed, may temporarily make the Mac usable again.
The whole error message says “Your system is running low on application memory. To avoid problems with your computer, close all applications you are not using. ”
Fix “Your system has run out of application memory” on Mac
There are a number of reasons why a Mac may encounter an error message that leaves the system without memory, and depending on the reason, it can be easy to fix the problem.
Cause: Error in macOS Monterey and see errors in system without memory?
If you’re using macOS Monterey and have a “Your system has run out of application memory” error message, be aware that this is a known issue with macOS Monterey and will likely be resolved in an upcoming system software update.
Solution: Disable custom cursor color / size
For macOS Monterey (and some Big Sur reports), some users have found that the system runs out of memory if they use a custom cursor color or a custom cursor size. If this applies to you, returning the cursor to the default size and color may resolve the issue.
Cause: The Mac hard drive is running low on storage space
A common reason why users may see the error message “Your system has run out of application memory” is if your Mac is running low on disk space. Therefore, freeing up available disk space so that you have at least 10% of the disk available as free storage can often solve the problem.
This happens because virtual memory, or exchange, is stored on the hard disk. When standard RAM is full, the operating system begins to use disk space to store RAM content, in a process called page or exchange.
If you have too much memory in the swap, and there is no free storage space on your hard disk, you will see the error message “your system has run out of application memory” until the application that uses all memory is resolved or closed, or the hard disk there is more free storage space.
Solution: Exit the application, which causes excessive memory usage
Close open files that cause high memory usage and / or exit the application causing the memory problem.
You can use the forced shutdown screen presented to you or the Activity Monitor if you wish.
Solution: Free up storage space
If you often see problems with a system that runs out of application memory, free up some disk space. Make sure there is no junk in the Downloads folder and empty the trash.
Try to have at least 10% of your Mac hard drive capacity available for optimal performance in general, not only with paging and virtual memory usage, but also for other tasks and activities.
Solution: Restart the Mac
Restarting your Mac will usually resolve the memory error, at least temporarily.
For users of macOS Monterey 12.0.1, this may be the only remedy until a bug fix is released.
Did you come across this error message on your Mac? Did you fix this by closing the app, freeing up disk space, updating macOS, or restarting? Did you find another solution to solve the memory problem? Let us know your experiences in the comments.
