Cheers, Matthias If you know your way around sed and such, it’s not that hard to script it.

Previously using PackageMaker this was an editable field and easy to set but in Packages it's a drop down list box and the highest version available to me is 10.8. Does anyone know a way of changing this? I've tried uninstalling Packages and reinstalling in case it populates the field during install time but I still have the same list of OS versions available to me. _______________________________________________ Do not post admin requests to the list.

This email sent to site_archiver@lists.apple.com That looks like a lot of work. I'm not sure whether the following works, but I would I love how you can modify the pkgproj file and run packages from the command line. For almost all of my cases I run scripts that modify the pkgproj file with sed (including version strings that are all over the pkgproj file), do the packaging, do the signing and have the final packages without any further intervention. If Packages has a check which values for IC_REQUIREMENT_OS_MINIMUM_VERSION are allowed this will not work, but it is worth a try.
