Encountering the “Your system has run out of application memory” error on your Mac can be incredibly frustrating, especially when you’re in the middle of important tasks. This error typically indicates that your Mac’s RAM and virtual memory are fully utilized, causing the system to struggle with running applications. In this comprehensive guide, we’ll explore the causes of this issue and provide step-by-step solutions to fix it. By the end, you’ll have a clear understanding of how to manage your Mac’s memory effectively and prevent this error from occurring in the future.
Common Causes of the “Your System Has Run Out of Application Memory” Error
Before diving into the solutions, it’s essential to understand the potential reasons behind this error:
Excessive Applications Running
Having too many applications open simultaneously can exhaust your Mac’s memory.
Memory Leaks
Some applications may have memory leaks, causing them to consume more memory over time.
Insufficient RAM
Older Macs with limited RAM may struggle to handle modern applications and multitasking.
Background Processes
Background processes and services can consume significant memory resources.
Large Files and Media
Storing large files, videos, and images can use up valuable storage space, affecting virtual memory.
Step-by-Step Solutions to Fix “Your System Has Run Out of Application Memory” on Mac
1. Force Quit Unnecessary Applications
- Action: Open the Apple menu and select Force Quit. Choose the applications you don’t need and click Force Quit.
- Benefit: This will free up memory by closing non-essential apps, reducing the strain on your system.
2. Restart Your Mac
- Action: Click the Apple menu and select Restart.
- Benefit: Restarting clears the cache and temporary files, freeing up disk space used as virtual memory.
3. Check Activity Monitor for Memory Usage
- Action: Open Activity Monitor from the Applications > Utilities folder. Click the Memory tab to see which applications are using the most memory. Quit or manage applications that are consuming excessive memory.
- Benefit: This allows you to identify and manage resource-hungry applications that could be causing the issue.
4. Monitor Memory Pressure
- Action: In Activity Monitor, observe the Memory Pressure graph. Green indicates sufficient memory, while yellow and red suggest a high memory load.
- Benefit: Monitoring memory pressure helps you understand how efficiently your Mac’s memory is being used and when action is needed.
5. Free Up Disk Space
- Action: Delete unnecessary files, videos, and images to free up storage space. Empty the Trash to ensure deleted files are permanently removed. Use a dedicated Mac cleaner app to remove junk files and optimize storage.
- Benefit: More available disk space means more virtual memory for your system to use, improving overall performance.
6. Update macOS and Applications
- Action: Open System Preferences and select Software Update to check for macOS updates. Update all installed applications to their latest versions.
- Benefit: Updating ensures you have the latest fixes and performance improvements, which can help resolve memory issues.
7. Reduce Browser Tabs and Extensions
- Action: Close unnecessary browser tabs, as each tab consumes memory. Disable or remove unused browser extensions.
- Benefit: Reducing the number of open tabs and extensions can significantly decrease memory usage, preventing the errors.
8. Manage Startup Items
- Action: Open System Preferences > Users & Groups > Login Items. Remove unnecessary applications from the startup list.
- Benefit: Fewer applications running at startup means less memory usage, allowing your system to operate more efficiently.
9. Clear Cache and Temporary Files
- Action: Use a Mac cleaner app to clear cache and temporary files. Alternatively, manually delete cache files from the Library folder.
- Benefit: Clearing out cache and temporary files can free up valuable memory and improve system performance.
10. Run First Aid in Disk Utility
- Action: Open Disk Utility, select your disk, and click First Aid. This tool checks and repairs disk errors that might be causing memory issues.
- Benefit: Repairing disk errors ensures that your storage is functioning correctly, which can help resolve memory problems.
11. Upgrade RAM (if possible)
- Action: If your Mac allows for RAM upgrades, consider adding more RAM. Consult Apple’s support documentation or visit an authorized service provider for assistance.
- Benefit: More RAM can handle more applications and multitasking, reducing the likelihood of encountering memory issues.
