Hi!
I just uploaded updated installation images 2020-04-19 for the
following Debian Ports architectures [1]:
* alpha
* hppa
* ia64
* m68k
* powerpc
* ppc64
* sparc64
These images should finally fix the installation process on Apple
PowerMacs and PowerBooks compatible with GRUB, so basically every
Macintosh using the New World ROM [2].
One user already reported a successful installation on his PowerMac
G5 and I expect installations to work fine on 32-bit machines, i.e.
G3 and G4 as well. But I'm looking forward to more feedback.
