While Apple users have long enjoyed a reputation for being shielded from viruses and malware, recent trends indicate that this is no longer a guarantee. The landscape of cybersecurity is evolving, with a notable increase in malware specifically targeting macOS. Security researcher Patrick Wardle highlighted this shift in a recent blog post, revealing that 2024 saw the emergence of 22 new Mac malware families, a significant rise from 13 in 2022.
Even in the absence of this surge, many malware threats exploit user behavior, relying on tactics such as phishing, cryptojacking, and USB jacking. Fortunately, there are protective measures available, but they require user vigilance and awareness.
XProtect: The Silent Guardian
One of the built-in defenses is XProtect, which operates quietly in the background, requiring little to no user intervention. This scanning tool continuously checks applications against a reference list of known malicious software. When a user attempts to open a flagged app, XProtect promptly issues a warning, detailing the nature of the threat. While this feature provides a basic level of protection, it is essential to keep your Mac updated to ensure XProtect’s efficacy, as its updates are crucial for maintaining an accurate list of threats. Unlike Windows Defender, XProtect does not allow for manual scans or extensive configuration.

Gatekeeper, another automatic feature, is designed to prevent the installation of “unsigned” software—applications from developers who have not been verified by Apple. Although rare, instances of malware breaching this barrier do occur. Gatekeeper checks for malicious software each time an app is launched, alerting users if they attempt to run an unsigned program. Users can configure Gatekeeper to only permit installations from verified developers and the App Store, enhancing their security posture.
<h3 class="article-bodysection” id=”section-the-one-that-contains-sandboxing”>The One That Contains: Sandboxing
Sandboxing is a familiar concept for iOS users and extends to macOS as well. This feature isolates applications from the operating system and each other, preventing unauthorized changes. In theory, even if a user downloads an infected app, it cannot spread beyond its sandbox. However, users often grant permissions without consideration, potentially undermining this protection. Additionally, apps not sourced from the App Store are not required to adhere to sandboxing protocols.
<h3 class="article-bodysection” id=”section-the-one-that-locks-lockdown-mode”>The One That Locks: Lockdown Mode
Lockdown mode is a relatively new feature aimed at countering cyberattacks. When activated, it restricts the functionality of various apps, including Messages and Safari, to safeguard user data from potential threats. Users can disable this mode once they regain control of their devices, restoring normal functionality.
<h3 class="article-bodysection” id=”section-the-one-for-the-web-safari-protections”>The One for the Web: Safari Protections
Safari, Apple’s web browser, incorporates numerous protective features against phishing and tracking. If a user visits a fraudulent site, Safari will block the page and issue an alert. Additionally, the browser offers a Privacy Report, detailing cross-trackers that Apple has prevented from accessing user data. Features such as alerts for weak passwords and Private Browsing further enhance user security while online.
<h3 class="article-bodysection” id=”section-the-one-for-login-credentials-passwords-and-passkeys”>The One for Login Credentials: Passwords and Passkeys
Apple’s ecosystem also emphasizes password security. Users receive alerts for weak or reused passwords and are notified if their credentials have been compromised. The introduction of Passkeys and the iCloud Keychain password manager streamlines password management, allowing users to unlock multiple accounts with a single password and set up verification codes for added security.
Do You Need Third-Party Antivirus Software on Your Mac?
With a robust suite of built-in features, one might wonder if third-party antivirus software is necessary. The answer varies based on the user’s device, software version, and usage patterns. While Apple provides comprehensive protection, a third-party solution can offer additional layers of security, such as VPNs or parental controls. Options like Bitdefender or Intego not only scan for malware but also provide backup solutions and identity theft protection. Depending on individual needs, investing in a third-party solution may be worthwhile, complementing Apple’s built-in defenses.
How to Stay Safe on Your Mac
Regardless of whether you choose to install third-party software, practicing good security habits is essential. Phishing remains a prevalent threat, so users should be cautious of unsolicited messages and avoid clicking on unknown links. Always verify the sender through a separate channel if unsure about a file or message.
Keeping software updated is crucial, as vulnerabilities in outdated systems can be easily exploited. Users should refrain from installing apps from unverified sources and avoid connecting to public chargers or USB drives. Utilizing a VPN when accessing public Wi-Fi can also enhance security. By staying informed and proactive, users can effectively protect their Macs and the sensitive data they contain from cyber threats.
