How to Fix Your System Has Run Out Of Application Memory

Open Wiki – How to Fix Your System Has Run Out Of Application Memory | For me, this takes place when my main system harddisk is running low on free space. Operating Systems utilize the harddisk for added memory storage, called “virtual memory “.(I’ve definitely always wished which the OS could just reserve enough space by itself, but it can not predict just how many applications we’ll be running).

Added to that, it’s worth noting that regular web use now requires far more memory laptop or computer did from the past. In activity monitor, you’ll notice that almost every tab & window (every open web page) is it’s own process, trying out a substantial slice of memory. Added to that, account for any ads, movies, flash, scripts, plugins and 360 videos etc. that any of us expect running smoothly. New OS’s and new web sites exclusively use lots of memory to deliver us with the services we expect to “just work” (eg. syncing across devices, notifications, automatic updating etc. etc.).

In short, for me there usually isn’t a single process that’s suddenly trying out a lot of memory (although a leaky program could indeed be described as a culprit – Sketchup 2016 performs this to me, for example). Typically, it is the additional functionality we expect for many programs/web plugins.

In my opinion restarting your computer always alleviates this problem for a short moment – primarily by unloading all of the webpages and apps we’d launched over time. But when our expectation in the computer and hardware constraints stay a similar (and we run a similar quantity of processes without changing anything else), eventually we’ll run to the problem again.

Two solutions from Demis at that work for me:

1) Open fewer tabs/pages and fewer programs at one time. Close some web-pages/programs before opening the hefty apps, such as MS Office, Parallels, 3D CAD, Adobe programs etc.

2) Free up more space on the system hard drive (eg. move all your music and photos to another drive), to allow the system to handle your typical virtual memory needs. For me, this means my 1TB OS drive needs >20% free space (200GB)! Your requirements may be different. If you’re on an older Apple laptop or iMac or Mini, the OWC Data-Doubler is a really fantastic way to accomplish this.

Method (1) is my temporary fix, so that when I eventually enact method (2) I will have restored the snappy performance I expect while running many heavy-duty programs simultaneously.

I follow these instructions to reset my Mac’s NVRAM and PRAM. The memory consumption went from 4.5 GB down to 2.8 GB when it started up.

  1. Turn off your Mac.
  2. Turn it back on again and press & hold Command+Option+P+R (all at the same time) before the gray screen appears.
  3. Hold the keys until you hear your Mac start up for the second time (let it beeps twice).

I had to repeat the process, one time right after the other, and now my memory issues have been solved.
