    I remember a while back I heard that in OS X you will almost always see you have little "Free" memory. Someone explained to me that this is because OS X, is designed to use all the memory it has to make OS X as efficient as possible.

    Now im trying to tell a friend why my mac always has little free memory and that I dont need to buy more RAM. Anyways i dont know enough on the subject to explain it well enough to convincce my friend. So im hoping someone here can.

    So shed some light on this subject for me please?

    You may need to buy more RAM depending on what you do...How much RAM do you currently have, and what do you do at once?

    i kinda wonder if thats true at all? i did check my ram usage from time to time. i doubt OSX intentionally uses more ram than other OSes.

    i too, would be glad to hear some new info tho.

    lol, I don't think so. I have 2.5GB of total RAM, and I usually have around 1.8-2.0GB free.

    windows vista has a pre-fetching feature that pre-loads the most commonly used programs into the RAM before you click them. That way when you do click them, they open right up.
