That's just cached memory. Pretty common practice for any modern OS to retain memory until 60% usage or so. Costs nothing and is snappier performance.
11GB idling is only after having done other things. When you launch it'll be less than 2 in my experience.
Ohhh right, I totally forgot about that. Remember reading about it somewhere. In that case, I guess it makes more sense.
Yeah you need to be careful what memory numbers you read - I’ve seen some of them hit terabytes on my Mac, and I only have a 256GB SSD so there’s no way that’s physically possible. Just because a memory address is tracked by the kernel doesn’t mean it’s actually being used. You can have a single region of memory counted multiple times (in my case, probably millions of times… I don’t think I was using much swap at all).
