Apple's sky-high RAM prices and strong resale values make this a tough call, though. It might just about be better to buy only the RAM you need and upgrade earlier, considering you can often get 50% or more of the price of a new one back by selling your old one.

Thankfully, Apple recently made 16GB the base RAM in all Macs (including the M2/M3 MacBook Airs) anyway. 8GB was becoming a bad joke and it could add 40% to the price of some models to upgrade it!
