I am having trouble creating a Pharos popup package in OSX 10.8 (Mountain Lion). The directions say to right-click (or Ctrl + click) on the Popup.pkg file but I do not have the "Show Package Contents" option. Because of this I am unable to go any furrther. I have tested my previous popup.pkg file created in 10.6 and I get a "Show Package Contents" option.
It looks like some have successfully created packages so how has this been done? I have not been able to find any third-party apps to modify package files- only to read them (i.e. Pacifist).
