"I'm sorry. I wasn't criticizing mjg59's work, but rather the amount of
work that's needed just to make an apple computer boot linux. If they'd
simply followed the standards it would've worked. Granted they had to
use something before uefi, but if they'd simply changed to uefi once
this became available this wouldn't be necessary. But apple being apple,
guess you can't really expect that.
