ℹ️ Check
Verify the macOS system is configured to authorize USB devices before allowing connection with the following command: /usr/bin/osascript -l JavaScript << EOS function run() { let pref1 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowUSBRestrictedMode')) if ( pref1 == false ) { return("false") } else { return("true") } } EOS If the result is not "true", this is a finding.
