Hi All, I'm newish to Mac and have a Mac Pro 3.1 dual 2.8GHz, etc. The machine came with a PCIe USB-3 card that uses the FL1100 chip and OS Lion which I upgraded to Mountain Lion, from a FREE download site. The Mountain Lion I downloaded is just the plant basic OSX 10.8 and from what I read, I need about version 10.8.5 in order to get the drivers, build into that version! But every time I check for updates, it just says no updates available. I could go the the Apple store and pay to download Mountain Lion , but will it be the latest version and solve my problem, or do you know a better way, can I just find and download the drivers, and how?? Any ideas and help most welcome. Regards Mel.
