Should I Update My Mac Operating System?

It’s important to regularly check for and install software updates on your Mac. Updates to macOS — the operating system on your Mac — might add new features to your computer, improve the power efficiency, or fix problematic software bugs.

Is it necessary to update macOS?

As with iOS, you may want to hold off on installing macOS updates automatically, especially because it’s a good idea to fully back up your Mac before installing such an update. However, installing system files and security updates is a very good idea, because these are updates that are essential to protect your Mac.

What happens if you don’t update your Mac?

No really, if you don’t do the updates, nothing happens. If you’re worried, don’t do them. You just miss out on new stuff they fix or add, or maybe on problems.
