Im using a new 15 inch MBP 2.16 with 1gb of ram. Anyway i have noticed two things when i open activity monitor. One is that even with only one Safari page open and one file downloading Safari is a memory pig. The other thing is that i only have 76.17mb free of physical memory. I have a couple of gb of virtual mem left. Anyway is it a Mac thing to use up that much memory? I dont even have iTunes open. Is it safe to start cancelling some processes?
 
Macs label their memory usage a little misleadingly. The free memory figure should be added to the inactive memory figure to see how much memory you really have available. Unless this figure is quite small, you probably have nothing to worry about. Safari does use up a lot of memory, but it'll cull that figure back once you start needing it in other apps. As a good way of testing if you need more, check your page ins and page outs a day after a restart. If they're quite high, then you may need more RAM.
