Yes, Mac has very good in-built security against viruses and other threats but it’s far from foolproof. You still need a top-tier Mac-focused antivirus to protect it from complex threats that macOS can’t handle. macOS comes in-built with:
Anti-theft tools — Lets you track your Mac and iOS devices in the event they’re lost or stolen.
App review — Checks the legitimacy of Apple Store apps before you download them.
Gatekeeper — Scans apps for malicious code before launching them.
Web protection — Blocks malicious tracking links and websites while using Safari.
In addition to these features, macOS is built on a sandboxed architecture that helps protect your system in the event of a malware attack. But even with these safeguards, there are still gaps in its security. A good antivirus can help make up for these shortcomings and mitigate the risk of malware, spyware, ransomware, and other threats on your Mac.
