Been having trouble recently with huge amounts of RAM being used, leaving me with less than 20MB free. Problem is, when I open Activity monitor, my user processes don't add up to anywhere near this. I Google'd it, and everyone says to make sure its set to show all processes, not just my own. But I dont have an option for that. The only processes it shows me are my user processes, there is no option anywhere to show other processes. I have seen screenshots of other people's AM, and there is a drop down box at the top for this purpose, but not on mine. I am using 10.6.8. Any idea what is going on?
