How to get rid of “Your computer is low on memory” pop-up or error on Mac

What is “Your computer is low on memory” popup or error

You may experience Your computer is low on memory message on 2 different occasions. Number one is a legitimate alert presented by the Mac system when you are running out of RAM. The system will, therefore, ask you to close some apps to free up space. This is quite common, especially if you have lots of programs working in the background that upload the PC. Sometimes malware can secretly gobble up memory resources and result in significant productivity loss. The second reason is that your PC was infected with adware or browser hijackers that modified your browser settings. In this case, “Your computer is low on memory” popup is fabricated and forces users into clicking on the “Close” button. Whilst it may seem innocent, frauds usually hide invisible buttons that can initiate multiple other processes that allow extortionists to take control over your browser. On top of that, browser hijackers tend to alter your homepage and replace the default search engine. This is made to push irritating ads, banners, and coupons along browsing to damage your Mac with other infections.
