So I just got this MacBook Pro (Retina, 15-inch, Mid 2015). And I feel like I'm using way too much ram for what I'm doing. It says I've used 7.9 out of 16 gb for just being on the internet (and having 3 tabs open) plus Activity Monitor. Is there a way I can cut the ram down or am I missing something? Btw I'm just on regular sites, no videos or games or anything.
