Causes of the “System has run out of application memory” error message

The “System has run out of application memory” error message can be caused by several factors. Understanding what causes the error message can help you prevent it from recurring in the future. Here are some of the common causes of the error message:

1. Low storage on the boot disk

According to MacPaw, if your Mac’s boot disk is running low on storage, it can cause the “System has run out of application memory” error message to appear. This is because macOS uses the storage on your boot disk as a virtual memory cache when the available RAM becomes low. If there is not enough free space on the boot disk, macOS cannot create virtual memory, causing the error message to appear.

2. Excessive virtual memory usage

As stated by Setapp, when your Mac runs out of available RAM, it starts using virtual memory to compensate for the shortage. Virtual memory is a space on your hard drive that macOS uses to temporarily store data that would normally be stored in the RAM. If your Mac is using too much virtual memory, it can cause the “System has run out of application memory” error message to appear.

3. Memory-hogging processes

Some applications or processes may consume more memory than others, causing the “System has run out of application memory” error message to appear. These memory-hogging processes can be identified using the Activity Monitor utility, which is built into macOS, according to Discussions.Apple.

4. Numerous open web browser tabs

According to MacKeeper, having multiple open web browser tabs can also contribute to the “System has run out of application memory” error message. Each tab in your web browser consumes a certain amount of RAM, and having too many tabs open at the same time can cause your Mac to run out of available memory.

5. Multiple smaller processes

As stated by OSXDaily, while individual processes on your Mac may not consume a large amount of memory, having too many smaller processes running simultaneously can also lead to the “System has run out of application memory” error message.
