Most computers are always connected to the Internet and maintain a constant stream of incoming and outgoing connections. Security is about what comes in, what goes out, and what modifies what. Besides, just as with personal physical safety, the best approach is a layered approach using multiple precautions in order to improve your chances of remaining secure. I use the Sophos Home antivirus product on my Mac at the moment, but it’s not helpful for telling me what it’s looking at and why, nor does it give me the ability to make decisions on what should be allowed and what shouldn’t. Antivirus software is fine, but a lot of malware doesn’t trigger antivirus programs, and targeted hacking certainly won’t.

When it comes to security, a little knowledge is half the battle â€” specifically, knowledge of what’s taking place on your Mac behind all the pretty windows and icons. macOS is essentially a Unix operating system with an Apple user interface, and that means it runs many common services and processes that hackers know how to exploit. Macs aren’t known for their malware and viruses compared to, say, Windows PCs, but all operating systems have security vulnerabilities.
