Hi, Low End Mac readers. My name is Robert Bryant, and I am a computer tech in Central California just south of San Jose. As a daily Mac Pro user, I wanted to provide the Low End Mac community with the necessary steps to take a base model or (that can now be easily obtained for under $500) and show you how to make it as modern as any current Mac, while retaining all of the expansion that the older tower style Mac Pros provide. Just like anyone else who frequents Low End Mac, I wanted to get more value out of my Apple hardware. Before going further into detail, I would like to give special thanks to MacRumors forum user “Tiamo”. Tiamo is the original modifier of the “boot.efi” file (more on that later) that allows you to run modern versions of OS X on the Mac Pro 1,1 and 2,1 which would otherwise be limited to. About the Project Recently, I have been helping friends upgrade their Mac Pro 1,1 and 2,1 models with (and more recently 10.9.4 and have also begun experimenting with with some success).

The whole idea of upgrading a Mac Pro 1,1 for me started out of a curiosity: I began researching how to use the nVidia 210 Silent video card (with no native Mac drivers) in my Mac Pro 1,1 and was disappointed after many dead-ends, finding no readily available answers, but I refused to give up. Many who I chatted with and messaged during my search for answers claimed it just wasn’t possible to use the nVidia 210 in a Mac Pro 1,1 without running Chameleon or other hackintosh tools to get or later installed (a necessity for using the nVidia 210 but not technically possible due to the 32-bit EFI issue), which I found disappointing to say the least. After all, this was a genuine Mac Pro and not a hackintosh build. After a great deal of persistence, I was thrilled to eventually find a native upgrade path (again, many thanks to Tiamo at MacRumors) that is not that hard to accomplish. Follow the steps below and you too can enjoy the affordability and upgradeability that a Mac Pro 1,1 or 2,1 can provide. Prep Work What you need to get started: • Obtain Mountain Lion (or later) installer: As you may have noticed, Apple’s App Store denies the installation of the unsupported versions of OS X because of a lack of hardware compatibility (this is typically pre-written into a bad machines list in the installer). Though all the Mac Pro hardware from the beginning has been fully 64-bit, early models that shipped between 2006 and early 2008 shipped solely with a 32-bit boot EFI and thus were artificially crippled when it came to full 64-bit operation.

To get around this problem, simply begin by downloading the installer on another Mac capable of running it natively. Regardless of what you do to accomplish this step, you will need a clean, unmodified installation package of Mountain Lion, or later before proceeding (we use Mavericks in this example).
