At one point, I was informed that the biggest advantage was that it
didn't require Forth programmers. From a management viewpoint, that is
significant, finding good Forth programmers is a pain in the tush.
Growing your own forth programmers isn't easy, it takes a long time for
someone to learn how to write clean and maintainable Forth. And with
today's larger PROMs, Forth's compactness is no longer as important.

I have no actual visibility into Apple's motivations, but my assumption
would be that with the move to x86, the change to EFI made sense to them.
