@davemark I have the 8gb M1 and would only upgrade to a 16.
8 is fine usually; I’m a light user. But when I’m doing school work (business) that involves tableau, etc running at once, i can the beachball a lot. Or if I wanna play a game at high resolution etc. Or if I want 3 tabs open in chrome (rarely) 😂 Hate having to close all my other apps out.
