Fixing 'Out of Application Memory' Errors on Mac

Experiencing an 'Out of Application Memory' error on your Mac can be a frustrating experience. This error typically occurs when your system is running low on memory, causing your applications to slow down or even crash. But don't worry, there are several solutions to this problem. In this guide, we will walk you through the steps to fix this error and prevent it from happening in the future.

Understanding the 'Out of Application Memory' Error

The 'Out of Application Memory' error is a common issue that Mac users encounter. This error message is a warning from your system that it's running out of memory. When this happens, your Mac may slow down, freeze, or even crash.

There are several reasons why this error might occur. One of the most common causes is having too many applications open at once. Each application uses a certain amount of memory, and when the total memory usage exceeds the available memory, you may encounter this error.

How Memory Works on a Mac: Every Mac has a certain amount of memory, also known as RAM (Random Access Memory). This memory is used to store data that is currently in use by your applications. The more applications you have open, the more memory is used.

When your Mac runs out of memory, it starts using your hard drive space as a temporary storage, which is much slower than RAM. This process is known as 'paging' and can significantly slow down your system.

How to Fix the 'Out of Application Memory' Error

There are several ways to fix the 'Out of Application Memory' error. Here are some of the most effective methods:

Close Unnecessary Applications: The simplest and most straightforward solution is to close any applications that you're not currently using. This will free up memory and may resolve the error.

To close an application, simply right-click on its icon in the Dock and select 'Quit'. Alternatively, you can use the 'Command + Q' shortcut.

Restart Your Mac: If closing applications doesn't solve the problem, try restarting your Mac. Restarting your system can free up memory and resolve any minor software glitches that might be causing the error.

To restart your Mac, click on the Apple menu in the top-left corner of the screen and select 'Restart'.

Upgrade Your RAM: If you frequently encounter the 'Out of Application Memory' error, it might be a sign that your Mac doesn't have enough RAM. In this case, you might consider upgrading your RAM.

Upgrading your RAM can be a bit complicated, as it involves opening up your Mac and replacing the memory modules. If you're not comfortable doing this yourself, consider taking your Mac to a professional.

Preventing the 'Out of Application Memory' Error

Preventing the 'Out of Application Memory' error is just as important as fixing it. Here are some tips to help you avoid this error in the future:

Monitor Your Memory Usage: Keeping an eye on your memory usage can help you avoid running out of memory. You can use the Activity Monitor tool on your Mac to check your memory usage.

To open Activity Monitor, go to Applications > Utilities > Activity Monitor. In the Memory tab, you can see how much memory each application is using.

Limit the Number of Open Applications: Try to limit the number of applications you have open at any one time. The more applications you have open, the more memory is used.

If you need to use multiple applications at once, consider using lighter versions of the applications, if available. For example, use the web version of an application instead of the desktop version.

Regularly Update Your Software: Keeping your software up to date can also help prevent memory issues. Software updates often include performance improvements and bug fixes that can help your Mac run more efficiently.

To check for software updates, go to the Apple menu > About This Mac > Software Update.


the 'Out of Application Memory' error on Mac is a common issue that can be resolved by closing unnecessary applications, restarting your Mac, or upgrading your RAM. To prevent this error, monitor your memory usage, limit the number of open applications, and regularly update your software. By following these tips, you can keep your Mac running smoothly and efficiently.
