I just saw this news from RPG Maker MV's Steam page, Regarding future macOS support, meaning RPG Maker MV may have problems with later macOS versions due to the deprecation of OpenGL support, removal of 32-bit support since macOS Catalina, and possibly Apple moving from Intel Core to ARM M1. So far Windows and Linux (and possibly iOS and Android) aren't affected and should continue to work but it could affect RPG Maker MV games including Lawmage Academy on macOS especially on M1 Macs and/or Macs upgraded to macOS 11 Big Sur.
I suppose using RPG Maker MZ could be an option to support future macOS versions but it's not simple. While many graphical assets and most DLC for MV work in MZ, plugins for MV may not be compatible with MZ due to code changes. Additionally, some plugins like the ones from Fallen Angel Olivia are not available on MZ and although the VisuStella plugins could be used as a substitute for the Yanfly plugins, the VS plugins lack some of the features from the Yanfly plugins for example, VS Save Core doesn't have options to show Gold, Time, and Variables that Yanfly Save Core can.
Maybe sometime I might do a video playthrough of Lawmage Academy. I had played it twice (0.6 and 0.7) and it wouldn't hurt to play it a third time.
