I did try once and computer freeze and just power button help. And I am
booting from iMac and do not have OS X installed just FreeBSD. And when
I installed FreeBSD I lef auto partition and now I have:

 gpart show
=>       40  976773088  ada0  GPT  (466G)
         40     409600     1  efi  (200M)
     409640  968474624     2  freebsd-ufs  (462G)
  968884264    7888864     3  freebsd-swap  (3.8G)

Thank you.
