When it comes to hacking or cybersecurity, both macOS and Windows have their strengths, but many professionals prefer macOS due to its Unix-based architecture, which is favored for programming and security tools. Additionally, macOS tends to have fewer malware threats compared to Windows, primarily due to its smaller user base and integrated security features. The prevalence of Macs at conferences could be attributed to their reliable performance and the popularity of many cybersecurity tools that are optimized for the Mac environment.
