Installed more RAM - using more RAM!

Please make sure you are not stressing over something that changed seven years ago. Starting with macOS 10.9 in Oct 2013, Apple rebuilt its RAM allocation scheme based on the principle, as other have stated, that unused RAM is wasted RAM. "Free RAM" may be good for Windows but the current metrics for Mac RAM evaluation changes in 2013 to "Memory Pressure" and "Swap Used."

If Pressure is in the green and Swap Used is zero or nearly so, everything is working perfectly.

This screenie is from my old 2010 iMac after updating to OS 10.9. Note how much of its installed RAM was being used, yet the computer was running perfectly at the time I tool the screenshot.

Here is an Apple support article on the subject: View memory usage in Activity Monitor on Mac - Apple Support

And another: Check if your Mac needs more RAM in Activity Monitor - Apple Support

The propeller-head version is here: https://developer.apple.com/library/archive/documentation/Performance/Conceptual/ManagingMemory/ManagingMemory.html#//apple_ref/doc/uid/10000160-SW1

If you are still worried about RAM usage, all you need do is to restart the computer once a week or so.

Looks good, you likely were usingSwap before & slower on some things..

Because macOS uses available memory. The more you have the more it can use.

Because unused RAM is wasted RAM. What value is unused RAM?

Nothing wrong with that. Looks good.

Looks fine to me. Remember that a restart refreshes everything, so no need of "memory cleaners" or any other aftermarket scams.
