A copy of the original firmware is stored on the hidden EFI Partition. This partition is created when you reinstall Mac OS X. To mount this partition: $ sudo mkdir /efi This will create the mount point for the EFI system partition $ sudo mount -t msdos /dev/disk0s1 /efi You could find it under /efi/EFI/APPLE/EXTENSIONS/Firmware.scap
But now we need to find a way for "EFI Firmware Update.app" to load the original Firmware. -- 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
