XProtect is Apple's native signature-based antivirus technology. XProtect both finds and blocks the execution of known malware. There are many AV and Endpoint Threat Detection and Response (ETDR) tools available for Mac OS. The native Apple provisioned tool looks for specific known malware is completely integrated into the OS. No matter what other tools are being used XProtect should have the latest signatures available. Rationale: Apple creates signatures for known malware that actually effects Macs and that knowledge should be leveraged. Impact: Some organizations may have effective Mac OS anti-malware tools that XProtect conflicts with. Remediation: Terminal Method: Run the following command to enable and update XProtect: $ sudo /bin/launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.XProtect.daemon.scan.plist $ sudo /bin/launchctl load -w /Library/Apple/System/Library/LaunchDaemons/com.apple.XprotectFramework.PluginService.plist $ sudo /usr/sbin/softwareupdate -l --background-critical
