Macbook was stolen
Hello.
Yesterday afternoon, my Macbook (late 2010 - OS X Mavericks) was stolen.
I already went to the police and they're investigating the circunstances on which this happened, like investigating security camera footage, etc. ...
I already changed all my passwords. Also, I went to iCloud, and decided to use the 'lock the Hard Drive' function.
Till this moment, I get the message that my Macbook wasn't 'locked', because he hasen't been contected to the internet.
Exactly how does this work? I mean, I had a password, that was required to access the Finder and, obviously, use the computer. But, how does the 'lock' work exactly?!
Also, in case I never find my Macbook... what are the tasks I need to perform, in other to make sure I erase the Macbook from any information of mine (like iTunes, App Store). If that time comes, I don't want a stolen computer to be related to any of my personal Apple data...
Sadly, I also had lot's od personal documents there... how does the 'erase HDD' work exactly?!
Please, I desperatly need any information I might find, in order to preprae myself for the worst. Also, eventualy, I might buy a new Mac. Excatly how can I make sure that my stolen one isn't 'connected' to a new one, in order to steal any personal information?
Thank you to anyone who might help me.
MacBook, OS X Mavericks (10.9.1)
