site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com One solution could be to have 2 packages and 1 meta-package: You can check the architecture with the arch(1) command line tool. It would be wise to check which values is returned on a 64-bit Mac.

Each package would have an InstallationCheck script that would return an error (64) if the architecture is not the correct one. I want to be able to check a machine for Intel or PPC then install the appropriate binary (I know…should be universal….not my binary)….how do I make that check?
