For years, the prevailing notion was that Mac users were largely immune to malware threats. This belief stemmed from a combination of a relatively small market share and the robust security features built into macOS. However, the landscape has shifted dramatically. Macs now rank as the fourth most popular personal computer brand, and with this rise in popularity, they have become increasingly attractive targets for cybercriminals.
As the question of whether Mac owners should invest in third-party antivirus software arises, a comprehensive test was conducted to evaluate the effectiveness of macOS’s built-in security measures against malware.
Testing the Waters of macOS Security
Historically, two key factors shielded Mac users from malware: their smaller demographic made them less appealing to attackers, and the inherent security features of macOS posed significant challenges for potential threats. However, the current reality is starkly different, with a plethora of malware specifically designed for Macs now available.
To assess the situation, Macworld undertook an extensive evaluation, subjecting a standard installation of macOS 15.6.1 to over 130 known malware samples curated by the non-profit organization Objective-See. The findings were promising, revealing that while macOS can be vulnerable if users ignore warnings and grant permissions, the built-in protections are generally effective.
“Going through the malware archive and ignoring/bypassing protection screens, I was able to install third-party software that requested access to my microphone, webcam, keystrokes, and other system functions,” reported a tester. “During testing, I was allowed to install the NRKIH88 background function, which functions as a trojan; the infamous MacSecurity suite was installed and created background functions, and the LamePyre malware created a mock Discord app that requested permission to record audio and video data. By the end, my Safari start page had been compromised and switched to a website offering Viagra for sale.”
Despite these vulnerabilities, the test concluded that if users remain vigilant and heed the warnings presented by macOS, they can effectively safeguard themselves against the majority of malware threats.
“If you’re the kind of Mac user who mostly sticks to the Mac App Store, trusted developer downloads, and pays attention to Apple’s warning prompts, macOS’ built-in protections are generally enough to keep you safe,” the tester noted. “There are safeguards in place that honestly do a great job of blocking or quarantining the most obvious malware and raising red flags before shady software can do real harm.”
As the digital landscape continues to evolve, Mac users are encouraged to stay informed and proactive in their approach to security, ensuring that they can enjoy the benefits of their devices without falling prey to malicious threats.
