Yes, it is possible for the police to track your MacBook. However, it is unlikely that they would do so unless they had a valid reason and followed proper legal procedures. It is a common practice for companies like DHL to track packages as part of their investigations. The way you described the situation makes it seem like the DHL workers are being aggressive and trying to intimidate you.

EDIT: they don't even know you actually ordered macbook, possibly don't even know what that is meaning they don't have any serials at all.
