Is there a way to get my macbook back since it is registered with an apple id and can be pin pointed.
that would be the job of the police. You can't just go get it, and Apple does not assist in stolen products, other than cooperating with law enforcement when necessary.
I have a similar question. My MacBook was stolen, yet I had find my Mac and Prey installed. I was unable to reach my MacBook or locate it, so I'm assuming it was wiped. If the thief registered the MacBook under his/her name following the wipe, could I find out through Apple who it's. Urges fly registered to by supplying the serial number/proof of purchase?
