I now run High Sierra (10.13.6) and MM1HD works fine. The only issue I have is that the HD version of the mansion I'm playing has bugs compared to the original version of the mansion (my own Custom Mansion, Luris) so that I can't access some of the money and end up with dead ends lacking necessary keys... But that has nothing to do with the OS, rather the HD-ing of original custom mansions...
