Miek Gieben : Ok I have a dual boot mac OSX / ubuntu in legacy mode using rEFInd. Should I try to convert it to EFI like this : https://help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_EFI_or_Legacy_mode or should a reset the mac back to factory settings and install ubuntu from scratch? I would like to keep the dual boot.
I have no experience with EFI. Does the mac use secure boot? It is possible/easy to install a new kernel without braking the EFI setup each time? I'm trying to figure out if the EFI mode has drawbacks compare to the legacy mode. If there is no significant drawback then https://bugzilla.kernel.org/show_bug.cgi?id=60635 should be clsoed as "wontfix" or something like that.
