MacBook Memory and Storage Upgrade
If your Macbook is running well as it is, then you probably don’t need to add any more RAM. For most everyday tasks, 8GB of memory is plenty. In fact, you can get along quite well with even less than that, if you’re just browsing the web and watching videos.
But if you're doing anything more intensive, like music production or video editing, then the more RAM your Mac has the better. You don’t necessarily need to install the maximum amount of RAM possible, but 16GB or 32GB are good starting points for more intensive tasks.
If you’re unsure if you need to upgrade your Macintosh RAM, it’s worth checking to see how much you’re currently using.
