How to find crash logs for iPhone applications on Mac, Vista and XP

iTunesConnect service — a web site that iPhone developers use to manage their published applications — has a separate area that will list all the synced crash reports from the application users.

However, not all of the crashes appear there, or are slow to appear. Thus, if you have a desperate problem with someone’s application, it’s a good idea to pick these up and send them to a developer.

Here’s how, in three major operations systems: Mac OS X, Windows Vista / Windows 7 and for Windows XP.

iTunes sync

Application crash logs are transferred to your computer each time you do a sync with the device, in the iTunes. Thus, first step is to sync with iTunes:

Sync your iOS device with iTunes.


Mac OS X

On the Mac, crash logs are kept at:

~/Library/Logs/CrashReporter/MobileDevice/<DEVICE_NAME>   (where ~ is your Home folder) 

Here’s an example, showing the crash logs on the Mac OS X. Device name is “iPhone AV” here:

There’s the .crash file and .plist file – archive them both and send to a developer. Actually, pick all the files you find there that have the name of the problematic application.


Windows Vista / Windows 7

Files are located here:

C:\Users\<USERNAME>\AppData\Roaming\Apple computer\Logs\CrashReporter\MobileDevice\<DEVICE_NAME>

AppData folder is hidden by default, so here’s how to access it.  Open a "Computer" window to your personal folder:  C:\Users\<USERNAME>

Then click on the address bar at the top which will change the display into Windows folder path, add \AppData to it, then click Enter:
    C:\Users\<USERNAME>\AppData


Now the App Data folder contents are visible, and you can open the rest of the path to the Crash Logs:

  C:\Users\<USERNAME>\AppData\Roaming\Apple computer\Logs\CrashReporter\MobileDevice\<DEVICE_NAME>


Windows XP

Location is here:

C:\Documents and Settings\<USERNAME>\Application Data\Apple computer\Logs\CrashReporter\<DEVICE_NAME>
