Using a VPN is the best and surest way to secure your Mac devices. As mentioned above, Macs have a lot of vulnerabilities, so with a VPN, you can have end-to-end encryption to guarantee safety from online threats. Here are additional tips on securing your Mac devices:
Use anti-malware software: Macs are more prone to malware than Windows PC, so make sure to use trusted anti-malware software. Some VPNs also offer built-in anti-malware software to protect your Mac from online threats.
Use a password manager: Macs have an iCloud Keychain built in the system that automatically generates a unique password and even encrypts them. This way, you can secure all your accounts and keep them safe.
Use Safari browser: Apple recently updated Safari security by allowing users to prevent cross-site tracking in Safri on Mac. This is amazing, as Chrome collects a lot of user data to generate targeted ads.
