Theft of my MacBook Pro 3 days after purchase

If you had Find My set up on your MacBook Pro, you may want to put it into Lost Mode, and check to see if it has been able to report its approximate location.

If your Mac is lost or stolen - Apple Support

If you do see a location, do not go there yourself to confront criminals in person. Give the location to the police.

Beware of messages that you may get from "Apple Support", the "Police", etc. claiming that they want to reunite you with your computer, and asking you to enter your credentials, click a link, or remove the computer from your Apple Account. These messages will be from criminals or other dishonest people who need your help to remove Activation Lock so they can set up your computer as fully their own.

The following was written for iPhones, but some of the same ideas apply:

Do's and Don'ts for lost iPhones - Switched Off - Offline - Beware of Phishing – Apple Community

Why would this be the responsibility of Apple – or of whomever you purchased the MacBook Pro from? Being the victim of a thief – but it wouldn't be covered by the warranty.

If you have homeowner's or renter's insurance, you may want to check to see if that provides any theft coverage.
