    I have 2Gigs of RAM on my blackbook, when I boot up my mac in the morning it starts off with 1.40GB of RAM then in a couple of hours it drops to 1.08 GB of RAM...while no programs are running or anything...is this normal?
    Thanks in advance.

    Background processes, like indexing files for Spotlight, probably.

    You have a PhD in computer science or something?

    Why does it bother you?

    The kernel uses free memory as it requires for the purposes of caching data from the disk... I rather have 0 bytes of free memory and a very efficient computer than having every last bit of my memory used stringently and sitting there idle.

    You tell him iW00t!

    Seriously, open the Activity Monitor app (/Applications/Utilities), sort by real memory usage and see what's leaking the memory. I suspect it's Safari that's eating the memory. Cure: switch to FireFox or Camino or restart Safari every once in a while.

    And what does your Inactive RAM start at and end up at?

    I won't worry too much about it really, I have been getting awesome uptimes way beyond what people get on Windows, and if there are any leaking applications I am just not noticing it.

    Then again I upped my memory to 4gb recently :)
