Finding Applicaiton crash/error/hang logs on mac

Hi Team,


Can someone suggest is it possible to get relevant information logs for any application crash or hang on mac in terms of relevant information which can be helpful in debugging?


  • Application crash
  • Application hang
  • System crash

Is this your own app your "team" is developing, or is this app a third-party app?


Crashing apps will usually produce crash data, though that data isn't particularly useful without the source code to the app.


If this is a released app of yours: Acquiring crash reports and diagnostic logs | Apple Developer Documentation


If this app has not been released via Apple, symbolication and related app-development discussions are here:

Diagnosing issues using crash reports and device logs | Apple Developer Documentation


If neither or something else entirely, maybe look here:

ls ~/Library/Logs/DiagnosticReports/
tail -f /var/log/system.log 


Hangs and such usually involve app source code and Xcode and Instruments, and details of that are in the Xcode docs.


System crashes (panics) are logged, but the details of those tend to be arcane at best.
