ℹ️ Check
Verify the macOS system is configured to enforce time synchronization with the following command:
/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.timed')\
.objectForKey('TMAutomaticTimeOnlyEnabled').js
EOS
If the result is not "true", this is a finding.
✔️ Fix
Configure the macOS system to enforce time synchronization by installing the "com.apple.timed" configuration profile.
