Hi all, I'm not sure if I have an issue here but I want other peoples opinions on this. If I open every single app on my iMac, the max amount of ram I ever seem to use is 5GB out of 8GB total (according to Activity Monitor). These apps include everything from Photoshop, Lightroom, Chrome, Matlab, Mathematica, the entire Microsoft Office Suite to the standard apple apps like pages, mail etc. I mean absolutely everything open at once. Yet I only use 5GB of ram? Does this seem right because in my mind applications like photoshop and lightroom alone should use that, let alone word/excel/outlook/powerpoint, matlab etc on top of that.

Play free mac games online. Very few card games have been developed for Macintosh which makes really difficult for Mac owners to play and enjoy card games online. Before buying a Mac or Macintosh computer, people research if the software that they use regularly has a Mac version available or not.

Is my iMac writing the rest to my startup disk or is it actually using that little ram for so many apps? System is a Late 2013 27' iMac w/ 8GB Ram running the latest El Cap beta. I'm on the fence on buying another 8GB and sticking it in there, so if it is writing to disk I'll bite the bullet however I don't want to waste money and find out I didn't need the extra ram. Thanks Edit: With very few apps open (chrome, finder & activity monitor) it uses 3.19GB.

So running 20+ apps only uses an extra 1.8GB ram? Hi all, I'm not sure if I have an issue here but I want other peoples opinions on this.

I've ran batch processing in Lightroom before and it's never gone above this.

A mate of mine as a rMBP 13' with 8GB ram and his behaves the same. The only way he could push it above that was by running a Win 10 VM in parallels with 4GB RAM assigned to it. I understand how ram works however ~25 apps (some big apps) using less than 2GB even at idle does not seem right.

Edit: checked the page ins for google chrome and they were into the hundreds of thousands. Lightroom was in the tens of thousands and so was photoshop. Most apps were in the thousands. Those page ins were just from idling newly opened apps.
