cochon Posted July 11, 2012 Share Posted July 11, 2012 this motherboard built-in USB 3. It works fine in Lion 10.7.4. But with 10.8 GM it won't mount external usb 3 hard drive. Did anybody have a same problem Just rollback iousbfamily and iousbmassstorageclass in DP3. Cheers Link to comment Share on other sites More sharing options...
