Are Macs More Secure Than Windows PCs? A Fresh Look at the Debate

At Mile High Cyber, we often encounter the question: Are Mac (Apple) computers inherently more secure than Windows PCs? This topic has been debated for years, and recent developments, such as Apple’s emergency patches for two zero-day vulnerabilities exploited in targeted iPhone attacks, add new dimensions to the discussion. 

Understanding the Recent Apple Vulnerabilities

In April 2025, Apple released urgent security updates to address two zero-day vulnerabilities in CoreAudio (CVE-2025-31200) and RPAC (CVE-2025-31201). These flaws affected multiple Apple operating systems, including iOS, macOS, tvOS, iPadOS, and visionOS. The vulnerabilities were exploited in “extremely sophisticated” attacks targeting specific individuals. 

While these attacks were highly targeted, they underscore that Apple’s platforms are not impervious to threats. The exploitation of such vulnerabilities demonstrates that even systems with robust security architectures can be compromised under certain conditions.

Comparing macOS and Windows Security

Built-in Security Features

macOS incorporates several security mechanisms, such as Gatekeeper, which verifies downloaded applications; XProtect, which provides malware detection; and System Integrity Protection (SIP), which restricts system-level modifications. 

Windows 11, on the other hand, includes features like Windows Defender Antivirus, Secure Boot, and virtualization-based security. Microsoft has also been proactive in enhancing security measures, especially following incidents like the CrowdStrike update issue that affected millions of Windows devices. 

Threat Landscape and Market Share

Historically, Windows PCs have been more frequently targeted due to their larger market share. However, as Apple’s user base grows, macOS becomes a more attractive target for attackers. The increasing number of vulnerabilities discovered in Apple’s ecosystem reflects this shift. 

User Behavior and Security

Security is not solely determined by the operating system but also by user behavior. Both macOS and Windows users can fall victim to phishing attacks, social engineering, and other user-targeted threats. Therefore, educating users on safe practices is crucial, regardless of the platform.

Conclusion

While macOS has traditionally been perceived as more secure due to its Unix-based architecture and Apple’s controlled ecosystem, recent events highlight that no system is immune to threats. Windows has made significant strides in improving its security posture, narrowing the gap between the two platforms.

Ultimately, the security of a system depends on a combination of built-in protections, timely updates, and user vigilance. Both macOS and Windows require proactive security measures to safeguard against evolving threats.
