I want to distribute an install package (.pkg) to install our Xamarin Mac application not through the App Store. Creating the pkg file seems easy enough after I selected my Apple Developer ID after checking "Sign the installer package" on the "Mac Signing" page under Build Options.
But I would like to add an "Agree to License" page to the install that the user must agree to after reading the license doc. Also I would like the change the background image. Note that I have not checked "Create installer package" on the Mac Build page under Build options - since we do not currently plan to distribute through the Mac App Store.
Does anyone know how I can customize the pkg install in the way I want?
