I have the same problem as you. I've just tried the tutorial on http://pubmem.wordpress.com/2011/04/09 /flash-efi-firmware-update-manually-on-a-macbook-51/
It didn't worked for me, Macbook Pro 5,5. It needs to boot 4 times, and then in the 5th boot apple's EFI works. Of course I tried with my macs version, but nothing... :( Maybe installing another EFI like rEFIt ?? I can't afford now buying new logic board... Thanks guysm, I thought i was the only one with this problem... -- 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
