Upgrading EFI from 32-bit to 64-bit on Mac Pro with 64-bit processor
 
I have been investigating the possibility of instalkling Fedora (Linux) on a separate drive on my Mac Pro. But the EFI is only 32-bit (even though the processors are 64-bit), and does not support the Fedora installation. Does anyone know of a workaround for this problem, or a way to upgrade the EFI?

There is no way to do that to the best of my knowledge.

Thanks. I have read of methods that are claimed to work, but I have no way to verify them. Let's see if anyone else has any input.

Found this on the internet, but I don't know enough to evaluate it.
