Tips For Safeguarding Macs
So, the answer to Can Macs get viruses? and Can Macs get malware? is sadly yes, they can. Apple does a great job of guarding against common security threats, but determined cybercriminals can still contaminate Apple devices. Here are some best-practice tips to help keep your Macbook safe:
Keep your operating system and installed software up to date.
Macs are already set up automatically to check for software updates and alert you when updates are available for you to download. A key aspect of avoiding viruses and other problems is downloading and installing these updates promptly since they contain the latest security features.
Use a VPN when connecting to public or untrustworthy Wi-Fi networks.
VPNs disguise your original IP address and replace it with an IP address in an entirely different location. This means that hackers and websites cannot trace your connection and find your exact location, making you semi-anonymous online. VPNs also encrypt your browsing data, so even if hackers could spy on you, they wouldnt be able to see what you are doing.
Keep the firewall enabled.
Be Careful With Fake Files
Sometimes malware or viruses might be disguised as an image file, word processing or PDF document that you open either without realising what it is, or out of curiosity to see what it is perhaps upon finding a strange new file on your desktop, for example.
The malware creators technique here is simply to give the malware a fake file extension. Most of us can see straight through this, but its surprising how effective an attack vector this can be.
These kinds of files often arrive via mysterious emails from colleague that you later discover have had their email hacked.

Better Protect Your Mac
One of the ways malware gets distributed onto a computer is through harmless-looking apps. This risk is greatly reduced by only downloading apps from vetted sources. Luckily, Apple has a built-in macOS tool that makes it possible to separate the good from the bad.
The available choices are:
- App Store: Allows apps only from the Mac App Store. This is the most secure setting. Apple identifies all the developers of apps in the Mac App Store, and each app is reviewed before it’s accepted. macOS checks the app before it opens the first time to be certain it hasn’t been modified since the developer shipped it. If there’s ever a problem with an app, Apple removes it from the Mac App Store.
- App Store and identified developers: Allows apps from the Mac App Store and apps from identified developers. Identified developers are registered with Apple and can optionally upload their apps to Apple for a security check. If problems occur with an app, Apple can revoke its authorization. In addition, macOS checks the app before it opens the first time to be certain it hasn’t been modified since the developer shipped it.
