How to Update Mac

Should you update your Mac?

Our team of experts strongly recommends you keep your Mac running with the latest software updates. Not only does this get you access to the newest features, but it also means your Mac is protected against software bugs or security breaches.

That said, if you’re dependent on certain software for your work, you should only update your Mac if you know that software will still be compatible. We advise you to always back up Mac laptop files that you rely on first as a precaution. After big macOS updates, it often takes a couple of months before every industry-standard software works reliably on that update.

Deciding to regularly update Mac software is more than just a routine task, as it's crucial for maintaining device efficiency and security. System updates, whether for macOS or to update Mac apps, contain vital enhancements to ensure your laptop or computer operates optimally.

In contrast, ignoring necessary or regular updates can expose your Mac to vulnerabilities and hinder its performance. That’s why keeping apps and macOS current is essential for a smoother and more secure user experience.
