  # Found the process hanging while unpacking the zip with ditto. Running it in debug mode and then running
  # the ditto command manually printed out a permission error inside the app bundle it was unpacking, which is 
  # certainly odd. Was trying a workaround where I would do the unpacking myself and then ensure proper permissions.
  # The offending file was inside 'installer/Custom/*.vcs' and the owner did not have write permissions. (--r--r--r).
  # There is an inconsistency with this theory though. Even the current sophos formula that only unpacks the installer
  # without executing it runs the ditto command. Why does it only hang after adding the after_install block? 
  # My computer? Not sure.
