My MBP was stolen the other week, a late 2011 model. I had a firmware password set up and orbicule undercover software installed. Having researched online you can't bypass the firmware security settings on the late 2011 model by removing a ram chip and resetting the pram 3 times. So it got me wondering how who ever it was who stole my mbp has managed to evade being discovered? Or simply put, make use of some body else's MBP. Would itbe as simple as to simply replace the hard drive and then you have yourself a new mac, or does the firmware password prevent this?, alas if you did replace the hard drive, with a new hard drive with a fully operational osx system preinstalled would you be able to operate the computer and login without having to enter a firmware password? I'd appreciate your comments as I'm hoping this will help me & others reading make security considerations on the new MBP I'm about to buy.
