As you might know for the upcoming macOS Catalina (10.15) Apple will require applications signed with a Developer ID to be submitted for notarization. An important requirement for notarization is that the application has a hardened runtime enabled. For that reason InstallBuilder now supports creating macOS signatures with the hardened runtime capability enabled, allowing the installers to be notarized by Apple. Here is an overview of the changes for InstallBuilder 19.6.0
