Macbook Pro M3 Pro Ram is always full.

I recently got a Macbook Pro M3 Pro with 18 GB RAM and 1 TB SSD. Even When using Safari and Vscode I ram is mostly near to 18 GB or using swap. There is no heat up, nor the fan start-up. My trash is clean too.



MacBook Pro 14″, macOS 14.3

I don't get it?


Looks normal. Unused RAM is wasted RAM.

You are hardly using any swap files (VM) at all. Memory Pressure is all Green— no Yellow, no Red...

This is not your old Intel Mac prior to OS X Mavericks 10.9 2013-2018 when "Compressed Memory" was first introduced.



what exactly makes you think you have an issue?



if it ain't broke don't fix it

On my previous MacBook M1 Air with 16 GB RAM, I never saw swap or my memory get full while working on the same or a slightly more extensive workload, such as opening MongoDB and Postgres. If the M3 Pro version is indeed better, it should not use swap or max out the memory under the same load.


I'm not exactly sure what caused it to use so much RAM with light work, which the M1 Air can easily handle.

It only makes sense to use as much RAM as available. Why would you not want to use RAM. Using swap on the other hand is of concern. Do you often see the use of swap?
