This could be a "Find My Mac issue". I'm not too familiar with how it works, but from what I've read, it seems if you lose your Mac it can be locked it or erased. This one's apparently been locked. The code is the one entered when it was locked using iCloud.

If your boyfriend claims to have locked it talk to him. In fact you might want to talk to him anyway because if you're holding a stolen Mac and it "phones home" you could be charged as receiving stolen property or accessory to a crime.

Since this has been locked by Apple, contact them for help....No amount of fiddling around will help here.

This is how its done:

It works on Mac OS X Lion only.

1. Launch the Terminal application on you Mac. Then run the following sequence of commands (one at a time):

sudo su

dscl . -delete /Groups/admin GroupMembership yourAccountNameHere

dscl . -delete /Users/yourAccountNameHere

2. Now reboot your Mac into single-user mode by holding Command-S at startup.

3. Once booted into single-user mode, run the following sequence of commands (one at a time):

/sbin/fsck -fy

/sbin/mount -uw /

rm -R /Users/yourAccountNameHere

cd /var/db/

mv .AppleSetupDone .RunLanguageChooserToo

rm -R /Library/Caches/*

rm -R /System/Library/Caches/*

rm -R /var/vm/swapfile*

reboot

Your Mac will reboot to the start of the initial Apple Setup program just like when you first powered it on after purchase. All clean and ready to sell or give to a new user.
