If you’re pestered by the crash reporter dialog window, then you can quickly turn the window on and off with a defaults command string. I use it to prevent aerofly5 running on macOS 10.13, a flight simulator from reporting a crash dialog when exiting even it ran fine.

You can disable the Crash Reporter dialog box by launching the Terminal and entering the following command:

defaults write com.apple.CrashReporter DialogType none

You can reverse this to show the Crash Reporter again by entering the following at the command

defaults write com.apple.CrashReporter DialogType crashreport
