Hello, I've noticed in the past that after a few days of use, the free memory on my 2009 MBP gets really low. I notice this because when I get bored I snoop around the activity monitor - I actually don't notice any type of sluggishness. I'm simply inquiring about this. What I've done in the past is simply just reboot my system. This seems to work, but I just restarted my system last night, left it overnight and now according to activity monitor my free memory is at 12 mb! During the screenshot, I have Firefox with two tabs opened, iChat and iTunes. That's it. Any input would be appreciated.
