Summary	08414: When running game 0.247 on Mac OS X, it seems to default to a non accelerated, non OpenGL video driver.
Description	When running game 0.247 on Mac OS X, it seems to default to a non accelerated, non OpenGL video driver. Adding -video opengl -renderdriver opengl returns video performance to the previous levels observed with version 0.224. Without these command line switches added performance is so bad as to be totally unusable on a quad core i7 system.
Steps To Reproduce	Run mame with no options on an intel Mac OS X system. Performance is so slow the system will appear to have locked up at launch, but it is actually running VERY slowly.
Additional Information	Mame 0.247 seems to default to a non accelerated, non OpenGL video driver. Performance was normal on version 0.224. Other intervening versions have not been tested.

You mentioned it is self-compiled. It is entirely possible your issue might lie in OS or Driver updates/changes which may be acting adversely. Could you try a pre-packaged 0.247 trusted compiled from source to see if the same behavior happens? https://sdlmame.lngn.net/ https://sdlmame.lngn.net/2022/08/31/mame-0-247-released/

No.23455 JimCarlTay Tester 5 days ago	Well, macOS builds are still being prepared in the GitHub CI, but I'm not sure as to whether any people using MAME on macOS is still experiencing this issue.
