39924: INFO: Where are macOS CrashReporter logs saved?

Last update: 05-06-2020


When an application crashes on macOS, a system service named "CrashReporter" captures information to a file that can then be used to diagnose the problem.

This note details where the CrashReporter stores these files.


The CrashReporter saves the relevant system information in a file in one of two places depending on whether you are logged in as an administrator or not.

The two locations are:

~/Library/Logs/CrashReporter, and


The first path is relative to the home directory of the current user. For example, if you are currently logged in as "doug" then the log file will be found in /Users/doug/Library/Logs/Crash Reporter.

The second is an absolute path from the root of the startup volume.

In both cases, CrashReporter creates a file named "ApplicationName.log" where "ApplicationName" is the name of the application. This is the file that may be requested by Mobility Technical Support if you run into problems with Mobility client apps on macOS.
