My experience with a Mac Pro (2009) is similar. I tried to boot from CD =
and USB with FreeBSD 10.1 and a -current snapshot from about 2 weeks =
ago. A MacBook Pro (2010) booted without a problem with the both the =
10.1 and -current USB images.  The MacPro will be available for more =
testing in a week or two.
