I run on 16GB. The thing is, it always seems to use up the amount of RAM you have. I don't have much open (XCode, Sketch, Chrome), but it's still using 15.36GB.

I run on 16GB. The thing is, it always seems to use up the amount of RAM you have. I don't have much open (XCode, Sketch, Chrome), but it's still using 15.36GB. That's including 720MB XCode, and 325MB Sketch. It's storing 9GB for apps and 4.8GB for file storage. Generally, this just makes things that bit faster. The more you can store in RAM (even trivial things), the better. I've never had any slow downs, and don't have to worry about opening Photoshop and Illustrator along with XCode, Sketch and 20 Chrome tabs.

I'm not too familiar with the internals of OSX, but I would be very surprised if that ram is actually really used. More than likely, it's just caching of things already on the harddrive. If you have a old fashioned mechanical drive it makes a lot of sense, but with modern SSDs, I doubt you'll feel it much. Unless you're a true poweruser, no one really needs more than 8gb by todays standards. I have 32gb because I maintain and develop 4 different codebases each with their own setup in different VMs. If I didn't do that, I could manage with 8gb just fine.
