How to Fix “Your System Has Run Out of Application Memory” on Mac
When your Mac suddenly displays the dreaded message, “Your system has run out of application memory,” it can bring work, gaming, or creative projects to an unexpected halt. This error indicates that your Mac’s available memory has hit its limit, which can lead to slowdowns, freezing, or even forced restarts. In this guide, we’ll break down what this error means and provide practical solutions to keep your Mac running smoothly.
What Does “Your System Has Run Out of Application Memory” Mean on Mac
Understanding Application Memory on Mac
Application memory on a Mac includes both physical RAM (Random Access Memory) and virtual memory managed by macOS. RAM temporarily stores active processes and data, while virtual memory uses your storage disk to extend memory when needed. When your Mac runs out of application memory, it means that both RAM and the available virtual memory have maxed out.
Symptoms of Running Out of Application Memory
When your Mac struggles with memory, you might notice:
- Slow performance
- Frozen or crashing applications
- Delays in switching between programs
- An increase in fan noise as the system heats up
Why Does “System Has Run Out of Application Memory” Happen on Mac?
- High Memory Usage by Apps: Certain apps, like browsers, video editing software, and design tools, consume a large amount of memory.
- Background Processes: Applications running in the background or set to auto-start can use valuable RAM without you noticing.
- Corrupted Cache or System Files: Over time, temporary files and cache data can clutter your system, slowing down memory allocation.
- Insufficient RAM: Older Macs with limited RAM may struggle with modern, memory-intensive applications.
- Memory Leaks: Some apps have bugs that cause them to use memory inefficiently, a condition known as a memory leak.
How to Check Application Memory on Mac
Using Activity Monitor to Track Memory Usage
Open Activity Monitor: Go to Applications > Utilities and open Activity Monitor.
Click the Memory Tab: This tab shows which applications and processes are consuming memory.
Interpreting Memory Pressure: Memory pressure provides a visual cue; green means sufficient memory, yellow means caution, and red indicates critical memory usage.
Additional Tools to Monitor Memory
Apps like iStat Menus and CleanMyMac allow you to track memory usage and receive alerts when your Mac is running low on application memory.
How to Fix “Your System Has Run Out of Application Memory” on Mac
Restart Your Mac: A simple restart can clear out temporary files and reset memory usage.
Force Quit Unused Applications: Press Command + Option + Esc to bring up the Force Quit window, or use Activity Monitor to quit memory-hogging apps.
Clear Application Memory on Mac: macOS offers built-in tools to clear cache. You can also use third-party cleaners like CleanMyMac.
Close Unnecessary Browser Tabs: Browsers, especially Chrome, can quickly consume memory. Limit open tabs to reduce usage.
Free Up Disk Space: Low disk space can restrict virtual memory. Clear out unused files, large media, and old downloads using the Storage Management tool in macOS.
Disable Auto-Starting Apps: Go to System Preferences > Users & Groups > Login Items and uncheck unnecessary apps.
Update macOS and Apps: Outdated software can lead to inefficient memory usage. Regular updates often include memory management improvements.
Uninstall Unnecessary Apps: Removing apps you no longer use can free up valuable memory and disk space.
Advanced Solutions to Fix “Your System Has Run Out of Application Memory”
- Check and Reduce CPU Usage: Apps that heavily use the CPU can also impact memory. Use Activity Monitor to identify and close these apps.
- Limit Finder Memory Usage: Clearing Finder’s cache and disabling preview options in Finder can help.
- Upgrade RAM: If memory issues persist, consider upgrading your Mac’s RAM. This option applies to some Mac models but is particularly helpful for older devices.
- Monitor Virtual Memory Usage: macOS manages virtual memory through swap files on your disk. If your Mac’s drive is full, it may limit virtual memory; freeing up disk space can help.
- Consider a System Reset: As a last resort, you can reset your system preferences or reinstall macOS for a fresh start.
How to Prevent “Your System Has Run Out of Application Memory” in the Future
- Regularly Clean Up Mac Storage: Periodically delete old files and empty caches.
- Use Memory Management Apps: Apps like iStat Menus and CleanMyMac can help you monitor and optimize memory usage.
- Avoid Overloading with Apps: Limit the number of open apps, particularly when using resource-intensive programs.
- Keep macOS and Apps Updated: Staying current with software updates ensures better compatibility and memory efficiency.
