gpart on macbook air

[Raoul MEGELAS]

Hi all,

i am trying to install FreeBSD current on  a macbook air
(internal ssd as you know):
resizing the osx partitions to leave some place to FreeBSD.

i noticed the following:

1. on freebsd, deleting a partition with gpart, say:

gpart delete -i 4 ada0
damage the osx boot.

of cours, booting with a backup disk and repairing the disk
make the trick.

2. refit does not recognizes the gpt freebsd partitions.
but it recognizes and boots a non gpt freebsd partitions.

googling a bit i found this:

on 2007: freebsd-on-macbook.html

is this still true?

if not, how to solve this problem?

Thanks a lot.

Raoul
