How to solve Application Memory issue on MacOS High Sierra?

macOS High Sierra, the latest version of Mac operating system, was released in September 2017. Along with its new features and patches, new macOS has brought several issues and vulnerabilities. Some Mac users complain about the problem with system application memory. So, if you updated your device to High Sierra and instead of working fast and smooth your device shows ‘You have run out of Application Memory, please, terminate some applications’ error, just read on.

Such situation usually occurs when your hard drive doesn’t have much free space. In fact, all operating systems make use of the hard drive for additional memory storage or ‘virtual memory.’ Moreover, regular website usage now needs much more memory than in the past. If you open Activity Monitor on your device, you will see that each of the tabs, windows and web pages has its own process that takes up a fair amount of memory. Don’t forget about all the movies, scripts, flash, ads, plugins and videos we wish to run fast on our device. To sum up, new OS and all the web pages collectively require lots of storage themselves just to provide us with the necessary services. Below we are going to list a few fixed to the issue that proved helpful for macOS High Sierra users.

Restart your device

Apparently, rebooting the device will alleviate the problem for a while simply on account of unloading your open web pages and launched apps. However, if we continue running the same amount of processes, sooner or later we will end up with this issue again.

Open fewer pages, tabs, and Apps at a time

It is recommended to close unnecessary web-pages and applications prior to opening new ones, especially such hefty apps as Adobe, MS Office, 3D CAD, Parallels, etc.

Free up storage on your hard drive

As was mentioned before, such issue with applications memory is rather typical when there is not much space on your hard drive. Therefore, just transfer all the music, photos and videos to some other drive. Don’t forget to use your iCloud drive offering 5GB for free per Apple ID. Doing so, you will help the system to operate your regular virtual needs. For example, 1TB operating system drive usually requires more than 20% free space which stands for 200GB! Such system requirements vary for each device and if you are the owner of an older iMac or Apple laptop, cleaning up the hard drive will be a great help.

Reset your Mac’s PRAM and NVRAM

  1. Turn off the device.
  2. Turn your Mac on again, then press and hold Command+Option+P+R until you see the gray screen.
  3. Hold the above keys till you hear the startup sound (you Mac will beep twice)

Note! Resetting PRAM and NVRAM may result in changes to the system settings. You may need to change the volume of the speakers, the screen resolution and select the boot disk in System Preferences after the reset.

Repeat the procedures one by once, and your memory issues will be solved. However, the reason might also lie in some request that your device’s memory system is unable to meet. In such a case, the best option is to reboot the device, go to Activity Monitor and observe the memory pressure.
