yes it does----sorry not too smart parkinsons slowed me downThere should be a log file under in OBS' Application Support folder (/Users/YOURUSERNAME/Library/Application Support/obs-studio/logs), would be helpful if you could find and paste anything crash-related from the latest file there.
Also if you say "it crashes", usually it should show macOS' own crash report window (with the option to restart OBS) - does that one appear?
No bother. You'd need to copy and paste that crash report here, otherwise we'd be no wiser what might be the reason for your crash.yes it does----sorry not too smart parkinsons slowed me down
