Check Text (C-268510r1131221_chk)

Verify the macOS system is configured to disable the guest account with the following command: /usr/bin/osascript -l JavaScript << EOS function run() { let pref1 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.MCX')\ .objectForKey('DisableGuestAccount')) let pref2 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.MCX')\ .objectForKey('EnableGuestAccount')) if ( pref1 == true && pref2 == false ) { return("true") } else { return("false") } } EOS If the result is not "true", this is a finding.

Fix Text (F-72441r1034469_fix)
