(UPDATE)
I've tried with Ubuntu 18. Even worse. Instead of GRUB, Apple's "Boot Recovery
Assistant" kicks in saying that, in order to boot from the chosen media, a
software update is needed.
And even in the case when you opt for the software update, upon next reboot
nothing changes. The Boot Rec

Hi,
I'm trying to install Ubuntu on an iMac Pro (2017) using the latest desktop ISO
(ubuntu-19.04-desktop-amd64.iso) but the installer hangs very early.
Steps to reproduce
1) Burn the ISO to a DVD or USB stick
2) From the system (EFI) OS chooser select the CD or USB devic
Sorry. I apologize. The systems boots. There was a mistake in the
command line I've used to set-up the system after the update (The -u
option was missing in my efibootmgr command). Yet the systems boots,

Good day.
I'm testing pure EFI boot capability on my iMac 7.1 (Late 2007, graphic card
ATI radeon HD2600 pro).
So far, with Ubuntu 14.10, i've been able to boot directly into a perfectly
working system using the EFI kernel stub.
No GRUB, no ELILO, no rEFIND, no boot manager

The whole system boots fine, but X is still failing to detect properly the

Hi, Christopher.
What do you really mean by "testing with the latest kernel"? I try to guess, so
please correct me if I'm wrong.
When the 3.19.0-16 kernel was installed, the process ended up with two vmlinuz
files: vmlinuz-3-19.0-16-generic and vmlinuz-3-19.0-16-generic.efi.signed.
Now, after th

initializing the graphic card correctly: during the boot process I can see the
magenta (or whatever color it is) screen with the Ubuntu logo and the typical
"five flashing dots".

Mmhhh... I don't know. Actually, I haven't tried to reinstall the whole
