I am able to reproduce this bug on my Mac Pro 6.1. Ubuntu 24.04.2 installer starts successfully, but 25.04 stuck on black screen after GRUB menu.
I found this thread on Reddit there somebody try different Linux kernels and looks like kernels >= 6.14.0.11 are unusable on old Macs. https://www.reddit.com/r/macpro/comments/1jjn8k0/ubuntu_2504_daily_build_on_macpro61/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2105402 Title: Plucky fails to boot on (older) Macs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2105402/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
