Theft and Security

I am going to be traveling to a third world country and the possibility of my Macbook Pro being stolen is 50%. I have already enabled encryption on all drives with Filevault to protect my data. I was exploring the option to enable the firmware password with the reboot - Command - R option, haven't done it yet. I ran accross a scoundrel in NJ offering to remove the EFI chip on the motherboard and replace it with a new reflashed one and to wipe the drives. Their site is:

If you click on his link about me under the website above you can read the discussions from theives on his site, sickening.

I don't know why apple would allow an institution or individual to run a operation to defeat security measures that its customers depend on.

If my Macbook was stolen, I wouldn't be as concerned about getting it back as much as some ahole somewhere using it for free.

I guess I will enable firmware encryption, i guess that will at least cost a theif $199.

If firmware password and FileVault encryption on main volume is enabled will I need to enable encryption in the recovery volume?

thanks
