If you want to get rid of the Your computer is low on memory Mac pop-up message, first you should figure out what is causing it to show. Ready? Let’s fix this annoying issue together.


What Is Your Computer Is Low On Memory Mac

Let’s start by explaining what the Your Computer Is Low On Memory pop-up message on Mac is and what it aims to achieve. This pop-up is a false warning claiming you need to close some of the running applications on the macOS. It tries to make you believe that your computer is low on memory. The alert which “Your computer is low on memory” fake error displays is:

Your computer is low on memory

To free up some memory, please close a few applications.

The real purpose of this pop-up message is to scare you into downloading an unnecessary program like an update manager. That app, in turn, is very likely to install additional rogue apps on the computer, such as adware and browser hijackers.

The scam message itself is related to browser-based issues, like browser hijackers and potentially unwanted extensions. Some of the unwanted programs may also access the macOS to acquire specific information, generate shady ads, and monetize their presence on the affected machines. They may create many documents in the Collection directory.

Also note that Mac users have been targeted by other scams as well, including Systemupdati.xyz and Advanced-checker.com. Such suspicious domains are associated with the generation of fake error messages and should not be trusted.

Your Computer Is Low On Memory – How Did I Get It?

Potentially unwanted applications (PUAs), like the one that might be behind Your Computer Is Low On Memory are well-known to be spread via dubious techniques that passively access Apple devices. One of the distribution techniques is software bundling. In other words, this false warning message may be a result of unnoticed PUP installations.

It all might have happened when you were setting up a desired application on the machine for the first time. The installer of this application might have also added the software related to the pop-up, like shown in the example image below:

Your Computer Is Low On Memory Bundling 2022

Unwanted software is usually promoted as a free extra added to the setup of various free programs (freeware). This is exactly how such apps get installed on the device without the user’s knowledge: by being hidden in the EULA or the Advanced/Custom install steps. So, in the future, read carefully all the details while installing software.

Another prevalent technique to spread PUPs on the internet is its presence on some third-party sites. Such sites usually have a bad online reputation. The Your Computer Is Low On Memory program might usually reside as freeware or a fake Adobe Flash Player update, like shown in the image below:

It may also be advertised as app that will help you improve your online surfing experience. Yet, this software might aim to deceive you to gain access to the system and begin delivering troublesome ads.

What Does Your Computer Is Low On Memory Pop-up Do?

Typically, a Mac low on memory warning occurs when there are memory-intensive processes that are taking up lots of RAM resources, not storage space. Since Your computer is low on memory is initially a legitimate system warning, hackers aim to misuse it in order to trick people to overlook their following actions.

A considerable piece of advice that may help you spot the reason why Your computer is low on memory is to look at the Activity Monitor right after the pop-up appears on the screen. Sometimes this step may help you notice some shady apps that are using system resources at that moment. But this is not always the case.

Results reported by a Reddit user whose 2017 MacBook Air was affected by this pop-up give evidence that the unwanted app associated with the pop-up may not appear in the list of the active programs.

Recently, I’ve been running into issues with my MacBook Air stating the above message; that I should close some applications when there aren’t any open (at least not that I can see).

So what could be done in this case? According to security experts, the number one explanation for that problematic warning is having inadvertently installed adware on the system. Therefore, the best you can do to get rid of Your computer is low on memory Mac scam is to complete a thorough removal process of potentially unwanted/harmful files from the macOS.

What else should you know about the “Your computer is low on memory” pop-up on Mac?

This upgrade pop-up should not be trusted. It might be misleading. Its goal may be to convince you to permit undesired apps to change different macOS elements. As a result, shady toolbars may be added to internet browsers, and online tracking technologies may be installed. The main pop-up that shows up looks like the following:

your computer is low on memory pop-up on macos

The pop-up message won’t go away that easily. It is a hoax notification that attempts to trick you to take unconsidered actions. So, don’t panic when it pop-ups again. Just keep on reading and find the steps to delete unnecessary files from the system.

The statement is cleverly crafted to appear without the macOS being able to detect it as an active process. The good news is that a professional anti-malware program couldn’t miss nasty files/programs. It is designed to catch all suspicious components and successfully delete them for you.

And don’t worry you are not alone in this battle. This Mac Low on Memory issue has become so common that lots of online communities and forums have at least one topic that covers it. We have spotted multiple users’ complaints on Apple community forums and other platforms. One user has stated the following:

I keep getting a warning that my mac is running low.
When I go into Disk Utilities the Hard drive says
Used 164.29GB Other Volumes 1.84GB Free 833.86 GB
The visual blue bar would not even take up 1/3 of its overall length
The processor is 1.6GHz Intel Core i5
8GB 1867MHz DDR3
Graphics Intel HD Graphics 6000 1536MB
It is also running really slowly

This is a very interesting complaint – the hard drive is not even 1/3 full. This state suggests that there may be something more to it than just an annoying notification. It could be the installation of a Mac virus program or a browser hijacker like SearchMarquis. Below you could see the web browser of a user whose Mac has been affected by both Search Marquis and Your computer is low on memory pop-up:

your computer is low on memory mac combined with search marquis infection

Is Your Computer Is Low On Memory a Virus?

No, Your Computer Is Low On Memory is not a virus, but it may be shown on your Mac because of some type of rogue program, or adware.

Rogue programs, like the one likely triggering this fake message, aim to trick victims into believing that their Macs are in bad shape. The rogue apps may also generate a report with other errors just to make you take an action that may endanger online security. The primary purpose may be to fool you into purchasing the full version of a “Speedup” software that can free up space by scanning the drive.

Overall, the number one thing you should do when you notice the Your computer is low on memory pop-up on your Mac is to check the security of the system.

Third-party software related to this fake warning could also contain dangerous files that can endanger the overall system security. These types of hazardous files could behave in a nasty way. They may be acting as:

  • Trojans.
  • Keyloggers.
  • Adware.
  • Browser Hijackers.
  • Miners for BitCoin that use your CPU and GPU.
  • Fake optimizers or hoax antivirus programs.

Another side issue that may happen as a result of having a PUP, like the one behind Your Computer Is Low On Memory pop-up on your Mac system is intrusive online advertising. PUPs like this adware are developed to present affected users with different kinds of ads:

  • Banners.
  • Pop-ups.
  • Web browser Redirects.

These ads might lead you to scamming or unsafe web sites. Obviously, unwanted applications can be dangerous. If you experience pop-ups, go below and find the instructions to eliminate undesired apps as soon as possible.

Users who have registered and then removed the error pop-up problem on the machine, firmly confirm that the use of anti-malware scanners significantly facilitates the process.

Still, if you prefer the manual removal, it requires a clean up of the following documents that were connected with the unwanted app:

→ Library/Application Support/runChmm
Library/LaunchAgents/com. updater.mcy.plist.
Library/LaunchAgents/com. updater.watch.mcy.plist

How to Remove Your Computer Is Low On Memory Pop-up?

If you intend to get rid of undesired apps manually, go, and find the steps below. If you still feel the need for an anti-malware tool that will scan all macOS libraries and delete suspicious files, you can find a reliable one in the automatic removal step.

Note: For Mac users who have multiple user accounts – the issue may be caused by an active Fast switching option on Mac OS. When this feature is switched on, the system uses more additional memory (RAM) to maintain the changes occurning on all users profiles. Since this setting is turned on by default when creating multiple users, it should be stopped manually. To do this:

  • Head to System Preferences.
  • Open the “Users & Groups” panel.
  • Click the “Login Options” menu.
  • Enter your password to unlock the access to settings.
  • Turn off the “Show fast user switching menu as” option.
  • Save the setting and lock again the configuration panel by clicking the icon at bottom-left.
