Mavericks and memory (Ram)

Hi


Anyone else noticed how Mavericks uses memory ?

I have a new Macbook Air 2013 with 4GB of memory and after a short wile.

The system have used 3.99GB of the total 4GB 😟 Isn't that a big problem. Thats can't be right.

I would think that the computer would suffer greatly after a short time of use and the computer

needs to be restarted. If thats true. The new Mavericks ***** big time on Computers with less

memory. Or is there something i don't know.


Thanks

Mavericks uses memory smarter than previous OS's, not necessarily less memory. Look at the swap memory if that is high then you have a problem. Also, if the mac is still running fast then there isn't a problem.

Good call on /usr/bin/purge

This seems to have been successful for me

It won't last. Mavericks has a new memory management system that will attempt to keep RAM full at all times, so purging it periodically is actually counter-productive. When the system needs to load something new it will begin to compress memory, then start purging the least used cached files to make room. Don't worry about RAM being full all the time, that's the way it's designed to be. See How to use Activity Monitor and click on the Memory box. As long as MEMORY PRESSURE doesn't turn Red, you should be find. If it does, time to shop for more RAM.
