If your computer is low on memory (RAM or ROM), it may slow down, freeze, or crash. However, there are many tactics, like cleaning up storage, closing unnecessary applications, and managing startup items, which you may use to deal with this problem and enhance your Mac’s performance.


Key Takeaways

  • The low memory message on Mac shows up whenever the available RAM or ROM in the system is insufficient.
  • Running too many applications simultaneously, large files taking up too much memory, malware, and operating system updates consuming too much memory are the common causes of low memory on a Mac.
  • Strategies for addressing low-memory issues include managing startup items, cleaning up unnecessary files, and force-quitting applications and processes.

This message will show up whenever your system is low on memory in macOS:

Tip: Upgrading your Mac’s RAM can improve performance and prevent low memory issues. 

Close Unnecessary Apps 

You can try to fix the low memory issue by closing all the unnecessary applications that are currently running. Some apps can consume a large chunk of your RAM, leaving less RAM for other applications.

Also, close all the unnecessary chrome tabs as they take a large amount of the RAM. This technique has also worked for other Mac users on the Unity forum.

Managing Startup Items

By managing startup items, you can reduce the number of applications and processes that launch automatically when you start up your Mac, freeing up memory and improving performance. Moreover, a suggestion for a startup item manager software on the eeHelp forum has helped several users save RAM and eliminate this error.

Tip: It’s a good idea to review your startup items regularly to ensure that only essential applications and processes are launching automatically.
Here’s how to manage startup items:

  1. Go To Login Items Tab: Click “System Preferences” from the Apple menu by clicking on it in the top left corner of the screen > “Users & Groups” > your user account in the left column.

Force Quitting Applications And Processes

Sometimes, an application or process may stop responding or consume too much memory, causing your Mac to slow down. In such cases, forcing quitting the application or process may be necessary. This technique has also worked for numerous other users on the Zotero forum.Here’s how to force quit applications and processes on a Mac:

  1. Open Force Quit Window: Press “Command + Option + Esc” on your keyboard. The “Force Quit Applications” window will appear as a result.

  2. Force Quit Programs: Click the program you want to close  > “Force Quit”.
Tip: It’s important to note that forced quitting an application or process may cause you to lose unsaved work or data, so it should only be done as a last resort.

Removing Malware And Other Malicious Software

Your Mac may become slower due to malware and other harmful software using memory and processor resources. Install antivirus software and run routine scans to identify and eliminate any harmful software to avoid this. Several users on the Apple support community have also claimed that this method has worked for them as well.


Personal Analysis

According to my research, the low memory error on Mac occurs mostly due to low RAM on the system. Therefore, closing the currently running applications or managing startup items should fix the issue. If it doesn’t, you can try the other solutions mentioned above.
