We have an app that is distributed in our .pkg installer (using pkgbuild and productbuild). Now we need to perform various system checks, eg. minimum macOS version and then continue or abort the installation, based on conditions.
When we do that in the pre-install script, it works but the user experience is not what we need. The installation aborts with a generic message. What we want is to show the progress, eg. which checks have failed and why, a link to open the installation log, and to gracefully exit the installation.
Is it possible to achieve all this without resorting to writing a custom installation mac app ?
