** Description changed: [Impact] MacBookAir7,1 (i5-5250U) MacBookPro12,1 (i5-5287U) iMac14,1 (i5-4570R) - With three older Macs I am trying Plucky versions from the past two - weeks or so fail to boot. + With three older Macs Plucky and Questing fails to boot. The built-in displays stay blank but the backlight is visible until I force the computers to power off. External video doesn't show anything. I have tried both installed (more below) and live images. With the live image the GRUB menu with "Try or install" does show up. All three do boot normally to 24.10 live images. The iMac has 24.10 installed which also boots fine. The two MacBooks have Plucky installed, one upgraded from an earlier version and one installed several weeks ago. Plucky booted fine until around 2025-03-16 when this boot issue started, both with the installed version and the live image. I know this because it caused me to set these aside until now when I had a chance to look closer and find a non- Mac computer that I installed on that date. [Test Case] Boot on above mentioned Macs. [Fix] Enable efi hack only on arm64. [Where Problems Could Occur] Non-arm64 machines that need this fix (highly unlikely) might not boot.
