Diane is using an app that was developed by her company for internal use. She is running the app on her MacBook Air (13-inch, Mid 2013). The app quits unexpectedly but never displays any error messages. The other apps on her machine work without issue and she has reproduced the issue with the app on another machine. She wants to help her development group isolate the issue. Which of the following troubleshooting tools or techniques would you advise that she use to best isolate the issue?
