rEFInd is definitely a slick and useful boot manager for multibooting. On this occasion I did not install it, but decided to remain minimalist, because I do not want to interfere much with the AppleMac installation. So, I created /boot/EFI/LINUX/ on /dev/sda1, leaving the original /boot/EFI/APPLE as was and copied in the LINUX/ directory just the gentoo kernel image, .config and System files. I named the kernel image 'bootx64-4.4.39-gentoo.efi' to differentiate from other images I will install over time. Then using the efibootmgr I set up bootx64-4.4.39-gentoo.efi as the default boot kernel and when the MackBook is started it boots straight into Gentoo, in what it feels like milliseconds. :-) When I need to boot into MacOS I have to press the alt key (aka Option ⌥ key) as I power it on and the Apple firmware boot loader takes over. What I don't know yet is if a MacOS upgrade will wipe the /boot/EFI/LINUX/ in /dev/sda1 as it upgrades the APPLE files, but it is easy to boot with a LiveUSB and copy over the Linux kernel once more. This way I don't have to bless a hfs+ partition, or mess about with the MacOS firmware files, bootx64.efi, or anything else. I wonder why Apple did not develop their boot manager to be able to identify and boot Linux kernels too, but are happy to make it boot MSWindows ... -- Regards, Mick
