My Macbook Pro was stolen about 2 weeks ago by a former friend/employee of mines. I went to authorities and they told me unless I know they got it they cant do anything about it bc I didnt actually watch them steal it. Also the other day my former employee puts my data accross the internet from my Macbook Pro and is currently holding it ransom. Nevertheless this employee bragged on FB about stealing my Macbook Pro. I want my computer back but its like the authorities are no help at all. Is there anything I can do ? I have my reciept of my Macbook Pro to prove ownership. Please help.
