if you going into the installer and get the prohibitted sign means the machine and serial is not listed in the compatible list machines in the plist files.. easy to sort .. but the software to change it is not so easy to find for the mpkg file.. i have done one that runs on mojave but not sure if it will work on anything prior . hope that helps
