The first thread is making a UniBeast created USB installation thumb driver for PC's. It will not install on a Mac Pro. If you are trying to install Yosemite on a MP 1,1, then I recommend you look for how to upgrade a 1,1 to a 2,1 at the MacRumor's Mac Pro forum section > http://forums.macrumors.com/forums/mac-pro.1/Hello everyone,
My system is a Mac Pro 1,1 with Mountain Lion 10.7.5 and the following specs:
Processor 2 x 2.66 GHz Dual-Core Intel Xeon
Memory 17 GB 667 MHz DDR2 FB-DIMM
Graphics ATI Radeon HD 5770 1024 MB
Hard disks 1 SSD 250 GB and 2 RAID 1TB each
I tried everything mentioned in the first post of this thread but I am unable to boot from the USB stick inspite of adding the following lines:
<key>GraphicsEnabler</key>
<string>Yes</string>
<key>PCIRootUID</key>
<string>1</string>
Could someone help me please?

This is way Off Topic for this thread. If you are trying install Yosemite on your MP1,1, you need to update your MP1,1 firmware (32bit) to 2,1 (64bit), period. See the MacRumor's Mac Pro forum section for a thread that walks you through the update.Thanks a lot for your response.
Is the upgrade to the 2,1 necessary? I have found a few tutorials on upgrading to Yosemite on 1,1. None of them so far have worked though. I feel it has something to do with my hardware. The odd memory that I have - 17GB and the particular slots they have been installed in. What do you think?

If you are trying to run UniBeast to make a USB Installation thumb drive, then you need to use UniBeast for Yosemite. But, you can not install Yosemite on a MP1,1 without first upgrading the Mac Pro's firmware to MP2,1.
