<p class="MsoNormal">It is my understanding that there is nothing different about macOS Sierra with regard to downgrading to an older version of macOS. Previous versions of macOS have always been able to be installed on any Mac, with the caveat that you must
do a clean install from bootable media and restore data from a backup. Can you cite a source stating differently? Any clarification is much appreciated. Thanks in advance.<o:p></o:p></p>
