Thanks. Best wishes. AndrewLi I have a stupid solution for this one if you can use a metapackage instead of just a package. In Package B, use an InstallationCheck script that will return 64 if the OS is Mac OS X 10.5 or later, 0 otherwise. It might be useful to also add a postflight script to delete this package receipt after installation (or remove it from the sqlite3 receipts data base on Leopard using the tool and option mentioned in a recent post (this will prevent this package from being discarded because it's already installed ). Depending on whether you use a distribution script or a good old metapackage, you might be able to hide the fact that it's a metapackage to the user or you can set Package B to be required.
