stewart1champ, I can just leave it posted if you like. All I did was remove the updater-binary and updater-script to instead use an update-script as follows:
show_progress 0.1 0
copy_dir PACKAGE:system SYSTEM:
set_perm_recursive 0 0 0755 0644 SYSTEM:app SYSTEM:framework
show_progress 0.1 100
Edit: Well, I also resigned it to!
