If you still have a drive with OS X on it, you may have
some luck with OS X's bless command:
I got a late 2012 mac mini to boot FreeBSD 9.1 (AMD64)
from a hard drive using 'bless' (unfortunately I don't
remember the exact command line parameters I used). If
you're looking to dual boot, the only luck I had (without
resorting to using third party software like rEFIt) was to
put the OS's on different drives and install FreeBSD using
MBR on the second drive.
