One of the security measures imposed by Apple limit installing apps from all sources on macOS. It is a useful security measure to prevent the installation of applications that are not downloaded from App Store or applications downloaded from the Internet but do not belong to developers identified by Apple. Applications without a digital signature.
Down to the operating system macOS Sierra it was allowed to install from all sources by simply checking the option "Anywhere"In System Settings > Security & Privacy > Allow apps downloaded from: Anywhere.
