I recently purchased a copy of StudioPro 11 64 bit. I'm running a MacPro on OSX Lion 10.7.5. After using it as plug in with PS (any version) it would not save the work when I returned to PS and constantly gave the message "Could not complete the Portrait Professional command because failed to open temporary tiff file: /var/folders/2q/9y3zkq9955s84y0vnr655n840000gn/T/PPfilt-1389109436-D488.tiff."
I opened up a ticket with their customer support and they advised me I needed to upgrade to Version 12. They sent me all the necessary links to do that. I suggest you do the same, contact them and upgrade to version 12 as it did indeed fix my issues.
