Mac users once skipped antivirus software — here’s why that’s no longer a good idea

In 2024, 22 new Mac malware families emerged, up from 13 in 2022, indicating a rise in malware targeting macOS. Built-in security features include XProtect, which warns users about known malicious software; Gatekeeper, which prevents the installation of unsigned software; Sandboxing, which isolates applications to prevent unauthorized changes; Lockdown Mode, which restricts app functionality to protect user data; Safari protections against phishing and tracking; and password security measures that alert users about weak or compromised passwords. While Apple's built-in protections are robust, third-party antivirus software may provide additional security layers. Users are advised to practice good security habits, keep software updated, avoid unverified apps, and use a VPN on public Wi-Fi.

How to Easily Uninstall McAfee Antivirus Completely

McAfee can appear on computers without user consent, often pre-installed on new laptops or bundled with other software. To uninstall McAfee on Windows 10 or 11, users can access the Settings app or Control Panel to remove it. For Mac users, the McAfee Total Protection Uninstaller can be used, but some residual files may need to be deleted manually. If standard uninstallation methods fail, the MCPR removal tool can be used to thoroughly clean up remnants of the software. Uninstalling McAfee is generally not detrimental, as many users prefer alternative antivirus solutions or rely on built-in protections provided by their operating systems.

Do Macs need antivirus? Debunking the security myth

Many users believe that Macs are immune to cybersecurity threats, leading them to neglect protective measures. This perception originated from Apple's marketing and the historical lower targeting of Macs due to their smaller market share. However, as the popularity of Macs has increased, so has the development of malware aimed at macOS. Reports indicate that malware targeting Macs has now outpaced that targeting Windows on a per-device basis. While macOS includes strong security features like XProtect, Gatekeeper, and System Integrity Protection, these are not foolproof. XProtect only defends against known malware, leaving users vulnerable to new threats. Macs are susceptible to various types of malware, including adware, Trojans, and phishing attacks. Antivirus software is important for Macs as it protects against evolving malware, shields users from phishing and online scams, enhances privacy protection, and prevents cross-platform threats.

Enhanced XCSSET Malware Targets MacOS Users with Advanced Obfuscation

Microsoft Threat Intelligence has identified a new variant of the XCSSET malware targeting macOS, specifically aimed at software developers who share Xcode project files. This variant features enhanced obfuscation techniques, updated persistence mechanisms, and a four-stage infection chain that begins with an obfuscated shell payload activated during the building of an infected Xcode project. The malware communicates with a command-and-control (C2) server to download additional payloads and employs encoding methods to hinder detection. It checks the version of XProtect to evade detection and modifies shell configuration files for persistence. The final stage involves an AppleScript payload that collects system information and redirects logs to the C2 server. The malware includes sub-modules for various malicious activities, such as stealing system information and extracting digital wallet data. Although observed in a limited number of attacks, its advanced capabilities pose a significant threat to macOS users. Users are advised to exercise caution with Xcode projects, keep systems updated, and use robust antivirus software.

Do Macs Really Need Antivirus? The Truth About Mac Security in 2025

Mac users have historically believed their computers are immune to viruses and malware, but this notion may be outdated as cyber threats evolve. The rise in popularity of Macs has attracted cybercriminals, leading to the development of sophisticated malware and ransomware specifically targeting Mac operating systems. Phishing attacks have also become more prevalent, using impersonation tactics to extract sensitive information from users. Built-in security features like Gatekeeper and XProtect provide some protection, but experts now recommend considering third-party antivirus solutions for enhanced security, especially when handling private information, downloading from unverified sources, or using Macs in business environments. While some users worry that antivirus programs may slow down their systems, modern options are designed to be more efficient. Ultimately, the decision to use antivirus software depends on individual digital habits and risk tolerance.

Do Macs Need Antivirus Protection?

Mac computers by Apple are known for their design, performance, and security features, but they are not immune to viruses and malware. macOS includes built-in security measures like Gatekeeper, XProtect, and Sandboxing, which help protect against cyber threats, but these features are not foolproof. High-profile malware campaigns, such as Silver Sparrow and Shlayer, have targeted macOS, highlighting the need for user vigilance. Antivirus software can provide additional security by offering real-time monitoring, continuous scanning, and privacy tools. Users who engage only with trusted sites and download apps from the Mac App Store may find built-in protections sufficient, but risks remain, including zero-day vulnerabilities and phishing attempts. Enhancing security can involve enabling the firewall, keeping macOS updated, using strong passwords, and activating FileVault for data encryption. While antivirus may not be essential for all Mac users, it can offer peace of mind, depending on individual online habits and data sensitivity.

Advice column: Which antivirus should I use?

The Digital Security Training team at the Freedom of the Press Foundation provides antivirus recommendations based on the type of laptop. For Windows 10 or 11 users, the built-in antivirus requires no subscription and should be kept updated through Windows updates. Windows 8 and 7 no longer receive security updates, making them vulnerable, and users are advised to upgrade to Windows 11. Mac users are not immune to malware, though they are less frequently targeted due to economic and technical factors. Keeping macOS updated and downloading applications from the macOS App Store may eliminate the need for additional antivirus software, as third-party solutions could increase risks.
