How much RAM you need is like how many calories you need to eat per day
Some people eat way too many compared to what they need
Some people eat just about the exact amount they need
Most people are somewhere in between (well, in the US, most people are probably in the former 🤒 but that’s another topic)
While I’m in the 8GB is enough for most ordinary users — they'll get by just fine — the food analogy, with a tweak, leads me to a different conclusion.
Suppose we're talking about how much food you stock in — and you can only shop once for the next month or year!
Better to buy
more than you need — guests might stop by or move in (new apps), your needs might change (more exercise, more apps, new partner), etc.
Buy too little and you're really stuck! And, you'll go hungry, and crave more!
Hmm… that makes me think about 16GB and dinner! 😎
Everyone needs to go look at Activity Monitor memory. It's all right there.
Playing off the title of the thread:
Why is everybody so obsessed with the Activity Monitor?!
As people have pointed out for years, Macs use up available RAM; it's SOP. As to AM: Yellow, schmellow!
What matters is what's happening to your workflow, whether you experience and notice slowdowns, whether they are tolerable or not (or infuriating), and whether there aren't some easy solutions — such as not running 20 apps simultaneously and not having 60 resource-heavy tabs open in a browser and not using ad blockers!
