Hello all, I am currently looking at a few cards to update a Mac Pro 2006 and 2009 to USB 3.0. Both have been flashed with the 2.1 and 5.1 firmware respectively. The cards that I am looking at are as follows: https://www.amazon.com/Inateck-Expr...pID=41DNpOxTFvL&preST=_SY300_QL70_&dpSrc=srch https://www.amazon.com/Inateck-comp...1538275435&sr=8-17&keywords=pcie+usb+3.0+card From the product page, the KT4004 is listed as mac compatible. the KT4005 is not listed as mac compatible, which happens to be the low cost version. Now, I was wondering, what defines the PCIE to USB 3.0 card as being natively Mac compatible?
