Any help you could give me would be greatly appreciated. Let me give you more detail about my problem. Well, and after a long weekend searching and trying different solutions (even bless), a friend of mine who knows a lot about Apple stuff mentioned the undocumented -firmware flag for bless. The MacBook isn’t booted that often (sleep ftw!), but it was quite annoying to know that something was kaputt. And as a result, every boot followed the firmware flash procedure because apparently, the flash flag (wherever that might be) stayed set: Long wait with a black screen -> Power light starts flashing -> A horrible beep -> Wait some more -> Start the boot process What i know for sure is, that my macbook wanted to flash a firmware afterwards.

I don’t know exactly what happened and why, but the installation from that daily disk didn’t finish on the one hand and didn’t let me specify the location where to install grub (i did find it out later on using the right disc). So i went on and downloaded the daily version assuming it would be the same.

I knew there were macbook specifc live cds (with grub-efi) out there from the alpha releases but I couldn’t find them on the beta download page. The Ubuntu 11.04 beta was released on April 1st, I had a spare external harddrive, some free time, so i had to try it out. ?Īnd now my story: what happened to me was the following. The Mac should reboot, flash the firmware and everybody’s happy again. Then shutdown and continue with the default firmware flash procedure for your device (e.g.: Unibody MacBook 5,1 – 1.3 EFI Firmware).Īnd that’s all folks. This is very important!! One needs to make sure to flash the correct version!!! Else bad things WILL happen! Then open a terminal and use bless (That command is one line and yes, -firmware is an undocumented feature): sudo bless -mount / -firmware /Applications/Utilities/MacBook EFI Firmware Update.app/Contents/MB51_007D_03B_LOCKED.scapĪgain: BE VERY CAREFUL TO USE THE RIGHT VERSION!!! THIS CAN BRICK YOUR DEVICE!!!
