    Hi guys, I'm just checkin activity monitor and it says I have 9.1MB RAM free (I'm using 4GB BTW) but 2.23 inactive. How do I make this memory available? I'm confused.

    The "inactive" RAM will be available if Mac OS X needs it. No need to worry.

    Free RAM is wasted RAM. Inactive RAM is stuff that's stored in RAM so it's available if needed (e.g. a hard drive cache), but it can be freed as needed to make room for other stuff.
