Poison already gave a more informative reply than I could have , but just to give a data point: I have successfully installed GRUB on an old Mac Mini from 2007 (obtained from a friend). The main hiccup was that I couldn't get any live CDs to boot in EFI mode, so I resorted to grub2-mkimage in order to "bootstrap" booting in EFI mode. Once that was resolved, grub2-install worked just fine, as long as I passed --efi-directory=/boot/efi. I have yet to test whether I can boot directly with GRUB or still need refind. (I was being stubborn and wanted to run what I found out after the fact is referred to as mixed mode, which allows a 64 bit kernel to access a 32 bit EFI, in which case you *need* a boot loader like GRUB. BTW, another thing I found out afterwards is that Debian apparently has mixed-mode live media starting with the Jessie release.)
