I hired a small company that specializes in Mac repairs, upgrades, etc. Guy came out to my house and installed Western Digital 500GB on my Macbook Pro 08 w/Snow Leopard. He told me to let it run and reboot. I did. Next day I noticed issues: -devices are not recognized by iTunes including my iPad; iPhone; iPod -iPhoto, see images but opens to black There may be more issues.... Does anyone know what the issue might be? Advice? I have tried repeatedly to get help from the person I hired and paid well. It's been over a week and he "guarantees" his work!
