I upgraded my MAC Mini with some MAC certified Crucial RAM from the 4gb standard to 16gb. While its running a ton faster and just overall better I have noticed while watching the Activity monitor that my utilization has slowly increased over the last few days since the upgrade. Memory pressure graphic is really low but my memory used is around 11/12gb of the 16gb?? Other than this Activity Monitor the only other program I have open on the desktop is Safari with 5 web tabs?? Any ideas why its running high now?
