I am not sure if I am following right but what you are trying to attempt is to run the Intel(R) Solid-state drive Toolbox in a MAC book PRO?
As far as I know there is no Intel(R) Solid-state drive Toolbox for MAC OSX.
You've mentioned that you boot from the Toolbox would that be booting from the firmware update tool?
Also the Intel(R) SSD 520 Series comes with the fimrware 400i, apparently that is the very latest firmware availble for this ssds.
Hope it helps!
