It's not driver specific - same happens with amstrad |

Is it a sudden onset (last version or two) or has it always been this way? Any way you could check some older builds? Opening this up to Direction Needed - I don't have access to MacOS. |

I suspected MacOS debugger doesn't disable side_effects somewhere but after some testing proved that's not the case. Apparently slowness comes from external OS calls not controlled by MAME at this moment. |

So, is this a MAME issue? Or not? I don't have a Mac to check this. |

It's hard to say "that's not MAME". Possibly there are some best practices for SDL calls we can apply to the layer, but that's beyond my expertise and I don't even have environment to properly test it. Report comes from my interaction with the user without development experience and in this situation is problemaric to guide him how to perform desired troublshooting. |

SDL interferes with the Cocoa event loop used by the debugger. This is what the Mac native OSD was intended to fix, but I can't get it to work and nobody with Cocoa experience has helped. |

Nobody familiar with Cocoa here who can review MAME's current state and make any suggestions? |
