Re: uefi boot on Apple Mac

If you're interested, you can try out the following ISO:
https://www.dropbox.com/s/srbunx0agrokcs3/freebsd-current-uefi-bios-amd64.iso

The image was built on Friday 8th of August for the amd64 platform.

I tested out the EFI part on VirtualBox (UEFI 2.X) and my MacBook Pro 17 
inch from 2011 (EFI 1.10), and as far as EFI goes, I successfully booted 
the image on both my Mac and VirtualBox (however, booting the image from 
BIOS using my Mac was a different story).

So, as I said, as far as (U)EFI goes, the image should work on UEFI 2.X 
based PC's and EFI 1.10 based Macs.

I wasn't aware of that, but thanks for the info. :)
