    Now that Apple finally has official support for USB3, will standard USB3 PCIe cards just work in Mac Pros? Has anyone had a chance to test in DP versions of Mountain Lion?

    My question exactly. I have a CalDigit USB3 card in my Mac Pro 2010 with CalDigit drivers, and it works great under Lion. I also want to know if USB3 cards work natively under Mountain Lion.

    By the same token, the version of Lion that ships with the MB's also supports USB3. Can anyone tell us what the Lion version is in these new MBP's and MBA's?
