I'm upgrading a Mac Pro 1,1 to Yosemite and it's easier than you'd think
if you have access to a Mac that can run it (Yosemite) natively. I got
it to work by hooking up a BlackX dock to my MacBook Pro 4,1, and
installing to an older 320gig drive. Then I booted the MacBook Pro from
that drive and upgraded to 10.10.2. Then I hooked the BlacX with the
drive in it to my Mac Pro and booted and HOLY SHIT, there it was all
nicely booted.
Of course, I can't do anything useful with it because I still have the
original 7300 GT video adapter, but that's easy to replace and the cost
is nothing really given that it will breath about 4 years of new life
into a very powerful computer.
Basically the steps are:
Hook a drive up to a Yosemite-capable Mac
Run the Install Yosemite application, and choose that drive
Let it install (takes its own sweet time)
Reboot the Yosemite-capable Mac from that drive
Let the system update to 10.10.2
Reboot from your original drive
Attach the drive you just installed to to your Mac Pro 1,1

On the drive you just attached:
Go into /System/Library/CoreServices and replace the boot.efi file there
with one of the downloaded files (renamed to boot.efi)
Go into /usr/standalone/i386 and replace the boot.efi file there
with one of the downloaded files (renamed to boot.efi)
Notes: the file in /System/Library/CoreServices is locked
the /usr directory is accessed from the Go To Folder menu item
you can probably use TDM instead of an external drive
Now y'all should be good to go, as they say. Reboot, and choose your new
Yosemite drive as startup.
I spent ages researching this stuff, with weird bootloaders and
modifications to obscure plists in the installer software and never got
anywhere. This just works. Now I'm off to find a good video card. Any
recommendations? I'm looking at 5770s.
Pisses me off that Apple don't support this stuff. I don't mind buying a
new video card, but I'm not buying a new Mac Pro looks like a coffee
grinder.
