If you have already installed the Sony Driver and it is not loading:
1) Restart (forces Mac OS to scan for unloaded drivers).
2) Go to System Preferences...Security & Privacy panel...General tab. You will see a message, "System software from developer "Sony Corporation" was blocked from loading." Click Allow.
3) Restart.

Note that you cannot "allow" a driver with connected remotely via screen sharing.
