I use a MacBook Air with 8 GB of memory and it's fine. If I've got a browser and VSCode and Blender and PrusaSlicer and Claude and XCode all open it gets a little slow, but Mac is very good at memory management these days.
Someone using just a browser and Word would have absolutely no problem.
What's so special about this Mac memory management? It uses the SSD better and makes swapping faster? It predicts what I'm gonna use or stop using and it swaps in/out accordingly?
I’ve used a computer with 4 gigs for the last 15 years and it still does emails, recipes, and YouTube. I.e. 100% of my computer needs.
