After pressing Escape to get the Game Menu, the game freezes on that title screen when I press the option "Save and Quit to Title", Since everything freezes, I do not get a crash report.
Playing mine craft Vanilla (no Mods) Single player, Lan World, Cheats on.
Only two option to unfreeze the game are;
I can to do a "Option-Command-Escape" to get back to the Finder, then do a "force quit" Minecraft in order to exit.
orRestart the computer, not the best of options.
