How to protect your MacBook against viruses and malware

It is often thought that Mac devices are exempt from viruses and malware, thanks to the security reputation that Apple has earned over the years. However, in a constantly evolving digital world, no platform is completely safe from threats.

As MacBooks become more popular, they also become targets for cybercriminals. For this reason, it is essential to adopt proactive measures to protect your computer. Discover at iRepairs the 10 fundamental steps to secure your MacBook and guarantee a safe browsing experience with no worries.

10 fundamental steps to protect your Mac

1. Keep your macOS updated

Apple works constantly to improve the security of its systems. For this reason, it is vital to keep your macOS updated to benefit from the latest security fixes. You can do it from the App Store or in System Preferences > Software Update.

2. Download apps only from reliable sources

Although it may be tempting to download programs from any website, we strongly recommend that you only install applications from the Mac App Store or from websites of known developers. Apple reviews all applications in the Mac App Store, ensuring they are free of malware.

3. Activate Gatekeeper

Gatekeeper is a macOS security feature that verifies software downloaded from the network. Make sure it is activated by going to System Preferences > Security & Privacy > General, and selecting «App Store and identified developers«.

4. Be careful with suspicious emails

Phishing is a technique commonly used by attackers to obtain personal information. If you receive an email that seems suspicious or asks you for personal data, do not open it and much less download attachments or click on links.

5. Consider installing antivirus software

Although macOS has built-in defences against malware, antivirus software can offer an additional layer of protection. However, make sure to choose a reliable antivirus and avoid downloading free solutions from unknown sources, as they could be disguised malware.

6. Enable the Firewall

Your MacBook's Firewall prevents unauthorised access to your device. Go to System Preferences > Security & Privacy > Firewall and make sure it is activated.

7. Use strong passwords

A good security habit is to use strong passwords and not repeat them on different sites. macOS even has a feature called Keychain, which can generate and store secure passwords for you.

8. Make backups regularly

In case your MacBook is compromised, having updated backups of your data is invaluable. Time Machine is a backup tool built into macOS that you can configure to make automatic copies on an external disk.

9. Disable non-essential services

The fewer services you have active on your MacBook, the fewer entry points attackers will have. If you are not using Bluetooth or location services, consider disabling them.

10. Educate your common sense

Cybersecurity does not only depend on software, but also on user behaviour. Avoid visiting websites of dubious origin and be wary of offers that seem too good to be true. Prudence is one of your best allies against malware and viruses.
