Stolen MacBook

If your Mac is lost or stolen - Apple Support

Apple does not track nor maintain a list of stolen computers.

Do not post your serial number in a public forum such as this help community.

if you can post here and if you know your serial number ,I'm fairly certain you can post or call apple support.

if not try contacting the nearest apple store for additional help.

good luck

There is no point in contacting Apple.
