Hi,
I ran into an issue where I lost the partition information on my
MacBook Air this afternoon despite not making any choices in fdisk.
I had previously setup my mid 2012 MacBook Air to dual boot with OS X
and OpenBSD/amd64 current but lost access to the OpenBSD partition
when I enabled file vault.
This evening I thought I'd try a new snapshot, so I decrypted the disk
by disabling file vault & booted the system off a USB flash drive
which I'd written the latest amd64 install58.fs image to.
I worked through the installed process and reached the disk selection
where I selected the onboard SSD and at which point the screen went
blank (I hadn't booted the system in legacy mode via bless) so I power
cycled the box with the intent of going back into OS X to bless the
system. At this point I discovered I couldn't my system again.
Disk utility indicates that the entire disk is now a OpenBSD partition.

I wiped the disk, repartitioned it again from disk utility in OS X
with 2 partitions, formatted HFS+ & fat.
Reinstalled OS X
reinstalled OpenBSD
reinstalled refit
sync'd GPT & MBR partition table
booted into OS X & enabled file vault
rebooted & disabled file vault
booted off the OpenBSD flash drive
went through the installer steps but after choosing the disk to
install onto I pressed the power button. (took a photo

Same thing, disk trashed
