Benjamin Peterson, this bug was reported a while ago and there hasn't
been any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please make a comment to this.

Title:
  "EFI Boot" from livecd fails on Macbook Pro

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I performed the following actions on my Macbook pro:
  1. Started it with the alt-option key down to bring up the boot menu.
  2. Inserted the Ubuntu 12.04 Desktop CD.
  3. Selected the "EFI Boot" drive and it enter.
  4. GRUB was loaded, and I hit enter to select "Try Ubuntu w/o installing it".

  At this point the screen goes black and it seems the machine must be shut off with the power button.
