Hi! Here are the first test images where the installation of GRUB on PowerMacs should finally work properly [1]. It took me quite some time and effort with lots of testing to get the implementation right.
During the partitioning phase, the installer will pop up an empty question dialog. Just answer that dialog with "<NO>" to continue. After that, the installation should complete normally. The installer now also correctly installs a boot script with an icon that should show up in the OpenFirmware boot menu that can be invoked with the <Option> key after the machine has been powered on. Let me know how the image works for you, then I can commit the changes for the grub-installer package to git when we know it works for most people for the time being. If it doesn't work, remember I need the installation log located in /var/log as the file "syslog". Thanks, Adrian > [1] https://cdimage.debian.org/cdimage/ports/snapshots/2021-04-14/ -- .''`.
