Okay.... Mountain Lion takes almost 2gb to run on my rMBP, my dock takes 136mb to run of "real memory" WHAT IS UP WITH THAT. I came from snow leopard and a mac pro, refusing to upgrade because I wouldn't use any of the new features. I have 16gb of RAM on this thing and I feel like that's barely enough! That would be DOUBLE what my mac pro has and I hardly hit the max on that thing (yes this is in part because Final Cut Pro 7 and CS4 are all 32 bit so one application can't use more then 4gb but still). I feel like I have to restart often! My free memory sometimes gets down bellow one gig. This is in part because Parallels uses like... 6.5gb but... I mean Safari with a couple windows open uses like a gig (yes I know this depends on the contents of the page). Is this really necessary? 4 years ago, 4gb of ram was plenty, it was a lot. I feel like there is almost no functionality change between then and now, and I know having a Retina display must add to it because it has to store bigger files but would it really be this bad? Someone explain to me how this has gotten so out of hand. I don't think this OS could even run on computers all that old. I don't know how it would work with like 2gb. But 2gb is a lot! Why... Is this just software bloat?
