The first time BizHawk is started on OSX, it consumes 100% CPU time on a single core for approximately 60 seconds, before showing the main window.
Also after the first time starting the app, the native file select dialog refuses to accept focus.
The native OSX menu bar doesn't like to respond to clicks. It also contains menu items that should be disabled, like the debuggers; choosing one of these unimplemented menu items appears to do nothing. Choosing the menu item a second time crashes the application.
The screen flickers uncontrollably. The display configuration options don't seem to provide any solutions.
No controller inputs work. Configuration is default (keyboard).
I also have trouble with loading a NES ROM I wrote; when loading the .nes file, BizHawk shows a broken "Choose File From Archive" window:
