@LightBurn Today when I opened MillMage I got this message. I hope you are planning to continue supporting the Mac version.
Using Intel-based apps on a Mac with Apple silicon
Rosetta enables a Mac with Apple silicon to run Intel-based apps. Support for Rosetta will end in a future version of macOS, so check with the app’s developer for an updated version.
If you get a notification that support is ending for Intel-based apps, and that the app or a component used by the app will not work with a future release of macOS.
