Zesty 17.04 x86_64 beta 2, while producing a bootable installation when installed on a MacPro, fails to appear in the Apple boot selector like a Fedora 24/25 installation does. It is trivial to emulate the Fedora approach by installing the mactel-boot-logo_1.0-1~xenial_all.deb and mactel-boot_0.9-1~xenial_amd64.deb packages followed by the commands...
sudo mkdir -p /boot/efi/System/Library/CoreServices sudo install -m 644 /usr/share/mactel-boot/SystemVersion.plist /boot/efi/System/Library/CoreServices sudo install -m 644 /usr/share/mactel-boot-logo/ubuntu.icns /boot/efi/.VolumeIcon.icns sudo echo "This file is required for booting" > /boot/efi/mach_kernel sudo install -m 700 /boot/efi/EFI/ubuntu/grubx64.efi /boot/efi/System/Library/CoreServices/boot.efi This produces an installation which shows the Ubuntu icon in the option-key boot selector on a MacPro 3,1. If Ubuntu followed this approach used by Fedora, the installation script for updating /boot/efi/EFI/ubuntu/grubx64.efi would have to be enhanced to install a copy in /boot/efi/System/Library/CoreServices as boot.efi (since the vfat partition used for /boot/efi doesn't support symlinks).
