In windows, you can press Control + Alt + Delete to bring up a task manager that says exactly what programs are hogging what portion of your RAM. I was wondering how i could do the same in OS X tiger. I have a rev A 1.42ghz mini with 1gb of ram and average around 250-300 in free ram... that means that i am using like 750 mbs or so of ram constantly. I want to know where this is going. For instance, right now i have safari, mail, adium, and finder open and have 300 mb of free ram, meaning 724 used or so. Where is this RAM going. PS: i coudlnt be happier with the performance of this machine, but would never reccommend anyone running under 1gb (all users that is).
