Once you've assessed your memory usage, follow these steps to free up RAM and resolve the issue:

1. Quit Unused Apps

Having too many apps running in the background can significantly consume your Mac's memory. It's necessary to quit unused apps promptly.

From the Force Quit Applications list, select the apps you want to quit and click the Force Quit button.

If the error message persists, move on to the next step.

2. Restart Your Mac

Restarting is the easiest and most effective way to resolve any problem with your Mac. Cache files and temporary files are automatically cleared when you restart your Mac.

3. Clear Disk Space

Another troubleshooting method is to free up disk space on your Mac. When your RAM is full, the system automatically swaps some files from RAM to a partition on your hard disk. While the size of this partition is not fixed, it is influenced by the amount of available disk space. If your Mac is running low on disk space, its performance can significantly decline.

To free up disk space effectively, consider using BuhoCleaner, a top Mac cleaning tool. With a few simple clicks, you can enhance your Mac's speed. No specialized skills or commands are required.

Here's how it works:

1. Download, install, and launch BuhoCleaner.
2. Click the Scan button and clear the results according to your needs.
3. Navigate to its other features to further clean up your Mac.

4. Close Unused Browser Tabs and Extensions

You may have numerous tabs open, and if you forget to close them, they continue to consume your Mac's application memory in the background. It's recommended that you close these tabs promptly.

Additionally, for an enhanced browsing experience, you might have several extensions installed in your browser. These extensions automatically activate when you open your browser. If you find some of these extensions unnecessary, remember to access your browser settings and remove them.

5. Reduce Login Items

Login items are apps that launch automatically when you boot up your Mac. As they launch, they consume a significant amount of memory space. To reduce memory usage on your Mac, you can also decrease the number of applications that launch at startup.

To do this, go to System Settings > General > Login Items, select the unnecessary startup items, and click the Minus (-) button.

6. Uninstall Unused Apps

It's a good idea to uninstall unused apps from your Mac as they can occupy a significant amount of your storage space. When you examine programs like Microsoft Office, Photoshop, iMovie, and Xcode, you may be surprised by the space they consume.

If you no longer need certain apps, you can delete them using the Finder or a third-party app uninstaller like BuhoCleaner. By doing so, you'll free up a substantial amount of disk space.
