• MacOS 10.13+ is now required.
• Mac quadra machines may crash on startup. If so, disable bgfx or switch to the OpenGL backend.
• Includes MAME 0.258.
• Reorganized the Macintosh hierarchy.
• Includes experimental Uthernet II / WIZnet W5100 emulation. Marinetti, IP65, and A2osX have been tested and should work. (This should make its way into MAME someday.)
