I don't know what the current migration status is of ZFS on FreeBSD to a
newer version.  I don't think -CURRENT/HEAD has a newer ZFS either, so I
think you're out of luck with regards to an "easy" migration.

If I was in your shoes, I would not downgrade the pool -- I would simply
stop using ZFS and use a filesystem that is fully compatible between OS
X and FreeBSD.  *cue someone chiming in with the usual "ZFS is
experimental on FreeBSD, blah blah blah" rhetoric*  :-)

Summary: you're out of luck.
