I have some issues with trying to get eOS to work on a mac 7.1. I've tried with nvidia-340 as it was recommended to a geforce 320m, but xorg won't start unless it's from recovery mode where it works fine but with software rendering hogging down the performance. Read somewhere that it might be a problem between grub and efi to recognize some bus for the gpu-card.

Here is some output (sorry for some swedish output, the system is for a relative)

lshw -c video
