How to Close All Windows on a Mac When It's Hard

When using a Mac, it's not uncommon to encounter issues with running out of application memory. This can happen when you have too many apps open at the same time, or if your hard drive is almost full. In this article, we'll explore the reasons behind this problem and provide some solutions to help you close all windows on your Mac.

Reason 1: Too Many Apps Run Simultaneously

One of the main causes of the 'system has run out of application memory' error is when multiple apps are running simultaneously. This can happen if you're a heavy user who likes to have multiple tabs open in your browser, or if you're running several resource-intensive programs at the same time.

To deal with this issue, try closing some of the apps that you're not currently using. You can do this by clicking on the 'X' button in the top left corner of each window, or by using the Command + Q keyboard shortcut.

Reason 2: Your Boot Disk Has Little Free Space for Running Apps

Another reason why your Mac may be running out of application memory is if your boot disk has little free space. This can happen if you've installed a lot of apps and files on your hard drive, leaving very little room for other programs to run.

To resolve this issue, try deleting some of the files and apps that you no longer need or use. You can also consider upgrading to a larger hard drive or using an external storage device to store your data.

Reason 3: Swap Files Take Up Disk Space

Swap files are temporary files that macOS creates when it needs more memory than is available in physical RAM. These files are stored on your hard drive and can take up a significant amount of space, especially if you're running multiple apps at the same time.

To free up some disk space, try deleting any unnecessary files or apps. You can also consider upgrading to a larger hard drive or using an external storage device to store your data.

Reason 4: Too Many Extensions Running in the Background

Finally, too many extensions running in the background can also cause your Mac to run out of application memory. This is because each extension requires some amount of memory to run, and if you have too many installed, it can add up quickly.

To resolve this issue, try closing some of the extensions that you're not currently using. You can do this by clicking on the 'X' button in the top left corner of each window, or by using the Command + Q keyboard shortcut.

In conclusion, there are several reasons why your Mac may be running out of application memory, including too many apps running simultaneously, little free space on your boot disk, swap files taking up disk space, and too many extensions running in the background. To resolve this issue, try closing some of the apps that you're not currently using, deleting unnecessary files or apps, upgrading to a larger hard drive, or closing some of the extensions that you're not currently using.
