FreeBSD on Macbook Pro early 2011

[Fred]

Hi everyone!

I am trying to install FreeBSD on my Macbook pro early 2011 in dual boot with OS X Mavericks but so far I could not boot on it once the installation is complete.

Computer specs: http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-i7-2.3-17-early-2011-unibody-thunderbolt-specs.html

I tried using the gpart command, blessing the partition, using gdisk to create an hybrid MBR, but so far nothing has worked.

Here's what I tried:

I also looked in the mailing lists, and the FreeBSD forums, but I could not find any solutions.

Now on latest versions of OS X Bootcamp (Mountain Lion, Mavericks) I cannot create a partition without having a Windows disk, and I also tried using Bootcamp under Snow Leopard.

Regarding the errors I have after the installation, it's either "can't load kernel" or "Missing bootloader", with or without hybrid MBR. The partition table is GPT, and the system uses a EFI boot manager.

Thanks in advance for any answer to my problem.

Cheers,
Fred
