Hi,

I have a Mac OS on Mojave v10.14.6, 15.4" mid-2015. 16 GB RAM until this morning working well.

After updating this morning the software (typical software updates required), my Mac is using 10GB of RAM, even with all my user applications closed. I have tried restarting the machine, no change, still using at least 10GB of RAM. I looked at the Activity monitor and there is no application using GBs of data. Any idea of what's going on and how can I sixths issue?

Thanks!

There is no need to micro manage your RAM— not since 2013 El Capitan introduced "Compressed Memory"

Unused RAM is wasted RAM.

If you are having a related issue, than state what those issues are.

The OS will clear used RAM and allocate the RAM you need for your app. This is by design and is very efficient. RAM is occupied by what the OS predicts will be needed so response time is very fast when what is needed is already available in RAM. The next time you run your app the RAM may already contain what is needed by that app. RAM is very fast and responds immediately to what is needed. Empty RAM is of no value.

You are not limited now. You were limited in the past. If 6GB RAM was reserved for other apps then you only had 10GB RAM available for your app. Now you have dynamic RAM so all 16GB is available for your app as needed. RAM, all of it, is used dynamically as required.

There are a lot of people with the same issue:

Just a tip before you open a new discussion, have a look and maybe you'll find other posts. ;)

What good is unused RAM? The OS manages RAM and will use all available RAM to improve your computer's performance. Unused RAM is wasted RAM. Why did you buy 16GB RAM if you did not want to use it?

Which update fixed it?
