Activity monitor shows finder using ~24 gb of RAM (screenshot below), when my machine only has 16 gb installed. I figure this has to be a bug because "Memory Used" only shows 9.62 gb, and I'm not experiencing any slowdowns. However, it's a little alarming and if there's an easy fix I'd like to take care of it. I'm using the most up-to-date Apple OS software as of writing (3/22/16). Thanks for your help!
