Just wanted to let you know that the solution from this website worked for me, but in a different way. I own a MacBook Pro 5.5.
http://pubmem.wordpress.com/2011/04/09/flash-efi-firmware-update- manually-on-a-macbook-51/ This it what made it work for me: Downloaded the the EFI update (1.7) from the apple website and unpacked it with unpkg. Blessing the .scap file while it was still in the contents of the MacBook EFI Firmware update.app did not work for me. I copied the .scap file (located in Contents/Resources) to my home directory. After I used this command: sudo bless -mount / -firmware MBP55_00AC_03B_LOCKED.scap The terminal didn’t give any output info and returned to my home directory. After I copied the .scap file back into the Contents/Resources directory (replacing the old one), From there on I followed the rest of this guide. I was so happy after days of trying that I did not pay attention anymore to what happened after the bless command worked, but when I tried to do the EFI update again it still said that my macbook was up to date with the latest firmware. So, did it do the firmware update anyway or was using the bless command actually flashing the EFI??? I wonder….. I hope this helps for other people with a macbook 5.5. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774089 Title: Booting fails 3 times, works every fourth time after new install of Natty Narwhal amd64 on Macbook Pro To manage notifications about this bug go to: https://bugs.launchpad.net/efibootmgr/+bug/774089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
