Akkete

When I try to open it says it doesn't work on OS X 10.11 or older. Sadly I have an old mac that can't be updated to newer versions than that. Is it known that it won't work on older OS X versions than 10.12? I tried running the mkxp-z directly from the terminal, which launched the game just fine (mostly fine, full screen didn't work, it didn't find my save files), but the game crashed when I was starting a new game (just after inserting a name for the player character).
