Q: Early 2008 Mac Pro to run Yosemite?

Hello all.

I have an early 2008 Mac Pro 3.1 with quad-core Intel Xeon and I am trying to do a clean install of Yosemite with a bootable USB flash drive.  When I power up the machine (while holding option key) I see the Yosemite installer.  I double click it.  I get the apple logo with the progress bar across the bottom, but it only gets about 25% of the way and then I get the circle with a line.  Any ideas?  I have upgraded the EFI per (EFI and SMC firmware updates for Intel-based Macs - Apple Support)

Thank you!

Mac Pro, Mac OS X (10.6.8)

    The installer flash drive is defective or you don't have a 2008 MP.

     

    Upgrading to Yosemite

     

    You can upgrade to Yosemite from Lion or directly from Snow Leopard. Yosemite can be downloaded from the Mac App Store for FREE.

     

    Upgrading to Yosemite

     

    To upgrade to Yosemite you must have Snow Leopard 10.6.8 or Lion installed. Download Yosemite from the App Store. Sign in using your Apple ID. Yosemite is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.

    How did you make bootable Yosemite installer on USB memory?

    My case:

    1) format USB memory with DiskUtility, named "Untitled"

    2) open Terminal.app, then type

    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction
