Good morning, My 3.5" > 2.5" Icy Dock just arrived so I installed the Intel 520 SSD into my Mac Pro 4,1 running 10.8.3. The SSD is not recognized, disk utility no help. Couldn't find anything online about incompatibility between Intel 520 and Mac Pro 4,1. Is the issue that it uses SATA 3? Of course the salesperson ensured that it would work fine and everything needed was in the box. Any advice would be appreciated. Thanks very much.
