PC Matic for Mac is an antivirus and security application for macOS (Sierra 10.12 and later), developed and supported entirely in the United States. **Core Protection Mechanism:** The product uses an application allowlisting approach via its proprietary SuperShield technology. Rather than relying solely on traditional blacklist-based detection, SuperShield blocks any executable not present on an approved allowlist. Blocked applications are flagged and sent to PC Matic's malware research team, which categorizes them as safe or malicious within 24 hours. Users can manually override blocks via an advanced mode. **Additional Security Features:** - Fileless script blocking to address script-based threats that do not write to disk - Brute force attack mitigation - Patch management to address known software vulnerabilities - Driver updates to maintain system integrity **Cloud Integration:** SuperShield leverages cloud computing to maintain and consult the allowlist in real time, enabling up-to-date threat assessments without solely relying on local signature databases. **Platform:** Compatible with macOS Sierra (10.12) and all later versions, including macOS Catalina.
