Unable to install Lockbox utility on iPod Classic 5g

How does "nothing worked" look like?

I correct myself.  Actually Rockbox installation on Windows works.  I installed Rockbox on VM windows.  So when connecting iPod, the iPod screen shows image of usb connector.  I did not see the prompt screen behind another window that select connection to windows.  The really issue is when connecting to Mac.  All I get is Do not disconnect with red circle and a cross bar on iPod.  I could not figure out what's seems to be the issue.
