Installed LMDE from there yesterday... Remaining problems: Key mapping with the Apple keyboard is a mess (especially so when your mind is on "it's an Apple keyboard, so I certainly have Apple shortcuts"), and there's a bunch of "irq xx: nobody cared (try booting with the "irqpoll" option)" messages during boot.
Contrary to the Debian notes for the macmini3,1 hardware, there's no problem with nouveau, but maybe that's due to using rEFInd instead of Apple's EFI bootloader?
I still have rEFInd somewhere, but it's not on the EFI partition that Linux sees? No idea where that is hidden now.
