My Latest email back & forth with OWC:
My Mac Pro is 3,1 early 2008. My understanding before purchase was that it would work in Mt. Lion and Windows.
Is there anyone who knows how to make this work?
This is a very well known issue that was discovered shortly after the 2006 Mac Pro first shipped.
Answer to my Question.
I am very sorry if you received conflicting information, but there is no known way to allow Windows access to those ports. It was blocked by Apple and they have stated repeatedly that they do not support those ports and will not do anything to update them to function in Windows.
