Where does my MacBook go with my RAM?

Question

macOS

Guys, there is such a problem that my MacBook constantly hides 4 gigabytes of memory from me somewhere.
I have the program CleanMyMac 3 through it, I see how much RAM is free and I always have it free about the 1st gig.
What to do ? I do not load the system with anything and clean it regularly

Answer 1

Don't worry, in OS X memory is always reserved and there is very little free space.
If necessary for any application, the system releases it. No cleaning required.

Answer 2

Look what eats memory and kill it

Answer 3

open the spotlight, write System Monitoring, open it, go to the memory tab, select
the desired process that eats so much and cut it down by clicking on the cross in the upper right corner, if you shouldn’t eat so much, google why it eats so much.
On this screen, you can see what cleanMM considers.
That is, there is not only RAM, there is also a cache
. And if you do a cleanup in cleanMM, then only the cache is cleared.
