I hope this is OK to post here?
I found this the other day, fheroes2 is an option for now that can run HoMM II natively on macOS, Linux, Android while Crossover support is getting there.
I have tested it a little bit and it seem to run MoMM II very good.
Description
fheroes2 is a recreation of the Heroes of Might and Magic II game engine.
This open source multiplatform project, written from scratch, is designed to reproduce the original game with significant improvements in gameplay, graphics and logic (including support for high-resolution graphics, improved AI, numerous fixes and user interface improvements), breathing new life into one of the most addictive turn-based strategy games.
