The quickest way to identify whether you need more memory is to check your Mac’s RAM usage. However, if you work with large images (bigger than, say, 100MB) or with huge databases or monster-sized spreadsheets, more RAM will be a huge benefit. Much of the work in generating frames for games, for example, is done by the GPU and its RAM. Better memory management, faster storage for caching files that can’t be stored in RAM, and blazing fast graphics processing units (GPUs) with their own dedicated RAM mean that the load on your main Mac RAM is less than it used to be. It used to be the case that adding more RAM would improve the performance of your Mac in almost every task. So the question of how much RAM to put in a new Mac is comes down to the balance between affordability and the additional benefit you’ll get from more RAM.

Adding extra RAM, whether you do it when you buy your new Mac or you add it later, costs money, quite a lot of money. Sadly, however, it’s not quite as simple as that. The simplest answer to the question: how much RAM do I need for my Mac is ‘as much as possible.’ You can never have too much RAM, whereas having too little can seriously affect the performance of your Mac.
